example of reusability in software engineering

Using our specifications of exogenous connector, we have developed exogenous composition framework (ECF) for system development. Two of these approaches are Component-Based Software Engineering (CBSE) and Model-Driven Software Development (MDD) which focus on reusing pre-developed code and using models throughout the development process respectively. The ability to reuse relies in an essential way on the ability to build larger things from smaller parts, and being able to identify commonalities among those parts. It aims to reduce development and maintenance costs and improve software quality due to the use of already designed, implemented, validated and tested software units [Sommerville 2011]. Reuse programs should start small and gain experience through pilot projects in order to be successful and effective. Having reusable software often helps to reduce development time for subsequent projects and hence allows faster time-to-market. Reusability brings several aspects to software development that do not need to be considered when reusability is not required. Most of the available software development methodologies do not explicitly identify reuse activities. In computer science and software engineering, reusability is the use of existing assets in some form within the software product development process; these assets are products and by-products of the software development life cycle and include code, software components, test suites, designs and documentation. A library of reusable components, one among the strategic engineering assets of any successful IT organisation contributes not only to productivity improvements but also to product quality throughout the life cycle of any software product. Standards compliance Some standards, such as user interface standards, can be implemented as a set of standard reusable components. Application reuse: An application may be reused either by incorporating it without change into other or by developing application families. interpolator in γ multiple steps under the condition that the order of downsampler/upsampler (i.e., J) is a positive non-prime value. documentation are usually written by and for different groups of people (for reasonable-sized projects), there is enough overlap that each could be improved by studying the communication strategies of the other. Software Reusability could even encourage those who believe that unit testing is a waste, to reconsider its practicality as it increases the applicability of the reuse code. These self-management systems involve recurring and ubiquitous tasks, such as data extraction for workload acquisition and more specific features that depend on the tuning strategy, such as the specification of tuning action types and heuristics. In its eighth edition, the book has again been revised and redesigned, undergoing a substantial content update that addresses new topics in what many have called “the engineering discipline of the 21st-century.” Entertaining and informative sidebars and marginal content have been expanded and make the book still easier-to-use in the classroom and as a self-study guide. Documentation has to be produced during the software process for various categories of readers. Subroutines or functions are the simplest form of reuse. Note 1: Examples of software engineering project proposals are available here. The term software crisis was coined in the late sixties to describe the increasing burden and frustration of software development and maintenance. Some of the attributes are platform specific, others are component-specific. RQ2: How can project authors that depend on a package react to its maintainer becoming unavailable? OLE controls may replace VBXes as implementations of the most successful component software model. Software compatibility helps the use of third-parties software components. Scale of software reuse: System reuse: Complete systems, which may include several application programs. Clearly, designers must carefully weight the tradeoffs between delivering a program and assuring reliability. OLE controls, like VBXes, are reusable, binary software objects with well-defined properties and I/O interfaces. Facets of software reuse Facet Examples, .2. Reusability is the ease with which something can be used repeatedly. Component engineering is software development for reuse. What can be reused? Cost-effective production of high-quality software systems is the primary goal of software engineering. The results show that the services identified based on the analysis of multiple product variants using ReSIde are more reusable than services identified based on the analysis of singular ones. As a live example, we recently explored Component Reusability for a client partner to bring in cost and time savings. Our model enables in-depth analysis of different kinds of exogenous connectors with respect to its static/dynamic behaviour in a system. We have defined a software process model that prescribes activity, document, tool, role, and metric issues. We distinguish four diierent models which are described subsequently see GoldberggRubin GR95 and Karlsson Kar95: 1. • Part 4, Managing Software Projects, presents software topics that are relevant to those who plan, manage, and control a software project. However, this kind of reuse can also be applied to documentation, where there is no source code involved at all. In computer science and software engineering, reusability is the use of existing assets in some form within the software product development process; these assets are products and by-products of the software development life cycle and include code, software components, test suites, designs and documentation. To validate ReSIde, we have applied it on three product families of different sizes. This can be accomplished by reusing components, applying proper change management across different variants, and leveraging … The scope of a domain can be chosen arbitrarily, either broad, e.g., banking, or as narrow as simple text editing. There are many attempts of implementing exogenous connector in different tools in unspecified ways. The next level is the solution domain specific and application domain specific components [7]. Technical aspects are important prerequisites for successful reuse. Moreover, we define incremental composition mechanism for this model to construct critical systems from a set of system requirements. Many reuse design principles were developed at the WISR workshops.[2]. This is especially true for organizations with a large number of product components and geographically distributed development teams. A taxonomy also helps in evaluating the state of today’s component reuse and in recognizing future potential for reuse. To evaluate our proposed approach, a case study of weather monitoring system (part of a disaster management) system was built using our EX-MAN tool. Hence, sharing it with the database research community may facilitate evolving state of the art on self-tunning strategies by enabling to evaluate different strategies on different RDBMS, serving as a common and extensible testbed. Students in Rutgers software engineering class developed those projects, and their reports and software code are also available here.. Given the variety of approaches and implementations, it would be desirable to evaluate existing database self-tuning strategies, particularly recent and new heuristics, in a standard testbed. Compositional reuse vs. generative reuse Reuse technique Composition Generation, Ad-hoc reuse of these models. The component group is responsible for finding and possibly adapting suitable components. years of investment may be required before it pays off, For example, the user interface domain may be regarded as subdomain of the airline reservation systems domain (and several others) [Pri87, Pri90]. However, these would mean a costly development process. All rights reserved. We begin by considering a number of common architectural styles upon which many systems are currently based and show how different styles can be combined in a single design. In the 1980s large-scale reuse programs were done. Four new chapters, emphasizing software security and the unique challenges of developing software for mobile applications, have been added to this edition. Candidate design features for software reuse include: Consensus has not yet been reached on this list on the relative importance of the entries nor on the issues which make each one important for a particular class of applications. During the creation and the establishment of the parts center, our group discovered what language features and what infrastructure were needed to enable the building and the distribution of reusable components. Applications should be built by assembling components. Therefore, we aim to analyze SPVs to identify cloned codes and package them using a modern systematic reuse approach like Service-Oriented Architecture (SOA). Existing service identification approaches identify services based on the analysis of a single software product. However, in many cases the development process is either ad-hoc or not well-defined. This panel will discuss some of the similar features and salient differences between program documentation and test documentation. A reusable component may be code, but the bigger benefits of reuse come from a broader and higher-level view of what can be reused. Programmers have been reusing code, subroutines and algorithms since the early days of programming. What are stages of reuse-oriented software engineering? In order to define the order of these steps and to establish transition criteria to progress from one step to another, models for the software development process were derived from other engineering activities [Boe88]. Note 2: This document describes how to develop a proposed software project in a structured manner. The areas of software engineering, software reuse, and software quality are discussed in the context of taking advantage of useful data in order to improve the software development process. After briefly discussing the meaning of the term evolution in the context of software, its technology, the software process and related domains, the paper describes some of the facets and implications of the evolution phenomenon as identified during many years of active interest in the topic, most recently during the FEAST (Feedback, Evolution And Software Technology) projects. Abstract Context The context of this research is software developers’ perceptions about the use of code examples in professional software development. In computer science and software engineering, reusability is the likelihood that a segment of source code can be used again to add new functionalities with slight or no modification. To bridge this gap, we propose a generalized polyphase multistep (GPM) structure. It provides an overview of economic analysis techniques and their applicability to software engineering and management. This thesis additionally contains an analysis of package distribution methods, and a focus on the problem of the long-term maintenance of single-maintainer packages. An important aspect is the integration of source code and documentation. Then we present six case studies to illustrate how architectural representations can improve our understanding of complex software systems. Academia got attracted to reuse in the late 1970s. They have to be generalized to satisfy a wider range of requirements and documented to meet the information needs of potential and actual reusers. This leads to multiple documentation of features that are multiply reused and may easily result in inconsistencies. Literate programming is primarily for system documentation. Software reuse, being a simple but effective technique for reducing the software development cost, appears in many forms from ad-hoc or white-box to systematic or black-box approaches. The benefits of reuse are quite apparent. Because reuse implies the creation of a separately maintained version of the assets[clarification needed], it is preferred over leverage.[1]. There is still a long way to go until systematic reuse of software components, especially beyond company boundaries, will be a matter of fact. One can also describe a component 's differences to other components. One way to achieve reuse is through software reengineering. Hammer a nail Hammer a nail again Hammer a nail again and again • Software reuse: don’t reinvent the wheel use the same knowledge more than once Hammer a nail Hammer a nut Hit an object with a force, Newton’s discovery … The central idea of literate programming is to improve documentation quality by describing problems and solutions rather than executable programs. Program documentation is a vital source of information for software engineers charged with making changes to complex applications. ! Their problem is that they mostly develop their applications in an ad-hoc manner: They do not have guidelines or methods which could help their developers in performing a new project and there are no ways to preserve experience made in performed projects for future use. • Hardware reuse use the same tool more than once, producing the same product more than once, etc. A design pattern is a general solution to a recurring problem. filtering operation at the lowest possible sampling rate. Strategic reuse helps you gain efficiencies across the entire product development lifecycle. In practice, developers often end up rebuilding software from scratch. Ad-hoc reuse among application groups 2. In the previous chapters we identified various aspects of software components, such as platforms, composition and interoperation. In this paper, for system architectures, we propose two styles: rigid architecture and flexible architecture. Cyber-physical systems (CPS) are composed of software and hardware components. Examples of architecture-specific components include event notification mechanisms, user interfaces components, and message passing systems. Component reuse: Components of an application from sub-systems to single objects may be reused. In this paper, we propose a reuse-oriented framework approach towards assessing and comparing automatic relational database tuning strategies. Our client, an enterprise software company and one of the leaders in travel domain, was maintaining 5 websites. As a motivation for this statement, we present a case study on reuse measurement in some literate programs. What is reuse software engineering? A library of reusable components, one among the strategic engineering assets of any successful IT organisation contributes not only to productivity improvements but also to product quality throughout the life cycle of any software product. Software Reuse Software Engineering Course Given by: Arnon Netzer What is reuse? The application group is encouraged to consider the use of components from the beginning of the project. • Part 1, The Software Process, presents both prescriptive and agile process models. I show that this is the case for a significant proportion of such packages. Thus components are created either by composition or by programming. Why Software Reuse Is Difficult . changes in organizational funding and management structures may be necessary.

However, for critical systems, a development method must provide ways to verify the partial system at different stages of the construction process. Domain-based reuse, All figure content in this area was uploaded by Johannes Sametinger, All content in this area was uploaded by Johannes Sametinger on Jun 06, 2014. It is also discussed that, for sample rate alteration applications, this modular feature of GPM structures can reduce the elapsed time and the hardware complexity compared to the conventional polyphase structure. The contributions of this thesis include a historical description of these changes, the refinement of existing processes, the design of new processes, the design and implementation of new tools to help the application of these processes, and the validation of these changes through rigorous empirical evaluation.Involving external contributors is also very useful at the level of the package ecosystem. A system architecture composed of independent components by coordinating exogenous connectors is in flexible architecture style category. In this paper, we propose a design pattern which defines coordination/communication program units (referred to as exogenous connectors) for a repository of reusable connectors in the EX-MAN component model. You will often write a piece of code, typically a library that you’ll want to reuse in another project. Object-oriented techniques, i.e., inheritance and information hiding, that ease reusing software, can be applied to documentation and thus, enable documentation reuse. Some of these systems are of critical nature, e.g., emergency or disaster management systems. https://www.igi-global.com/dictionary/teaching-oop-cop-technologies-via/27713 In addition, new content has been added to many other chapters. I give a first look at an emerging model of community organizations for the long-term maintenance of packages, that appeared in several ecosystems. RQ1: How prevalent is this threat? Software reuse has many technical and nontechnical aspects, for example, ad-hoc reuse, institutionalized reuse, black-box reuse, white-box reuse, source code reuse, design reuse. Many such systems (e.g., IoT based systems) are created by composing existing systems together. Software systems contain all relevant ‘information’ in order to be executable on a machine. Another interesting example of a successful application of software reuse is the program to generate color slides on a color CRT developed by Standish [27]. In the literature they sometimes have different semantics but are often used interchangeably. Coq has been developed at Inria since 1984, but has only more recently seen a surge in its user base, which leads to greater concerns about its maintainability, and the involvement of external contributors in the evolution of both Coq and its ecosystem of plugins and libraries.Recent years have seen important changes in the development processes of Coq, of which I have been a witness and an actor (adoption of GitHub as a development platform, first for its pull request mechanism, then for its bug tracker, adoption of continuous integration, switch to shorter release cycles, increased involvement of external contributors in the open source development and maintenance process). One common example of reusability is the spreadsheet program. Software Engineering (BCS PGD) Guidance from Ms.Dilshara Weerasinghe ... Software Reusability it is the ability that a software or a component is constructed in such a way , that it could be easily adopted , modified or reused in other projects in future. This is the reason that the amount of the component's potential reuse should be estimated to allow the estimation of the reuse effectiveness. NO! Access scientific knowledge from anywhere. We further use it for developing the modular decimator and The clone-and-own approach becomes a common practice to quickly develop Software Product Variants (SPVs) that meet variability in user requirements. Test automation, although very valuable, is often a very expensive effort where the ROI becomes questionable. The opposite concept of reusability is leverage, which modifies existing assets as needed to meet specific system requirements. The major advantage of software process models is their guidance regarding the order in which to fulfill certain tasks. Repository-based reuse among application groups 3. Finally, we survey some of the outstanding problems in the field, and consider a few of the promising research directions.

Quality in this respect comprises attributes like reliability, robustness, user-friendliness, efficiency and maintainability. The following are illustrative examples. Finally, when even low-level components are not available, they have to be implemented in some programming language. Significant progress was achieved when object-oriented languages like C++, which support reuse inherently, became available. Objective The primary objective of this paper is to identify the human factors that dominate example usage among professional software developers, and to provide a theory that explains these factors. Although both types of, . Or they can only reuse a small fraction of existing code in new projects. In the latest technologies for next generation using in Cyber-Physical Systems, 5G and IoT (Internet of Things) based solutions have a significant contribution. Build frameworks that are modular and can be easily reused. Usually broad domains are built on top of several narrow domains. One kind is responsible for computation and the other kind is responsible for communication. Reusability implies some explicit management of build, packaging, distribution, installation, configuration, deployment, maintenance and upgrade issues. Centralized reuse with a component group 4. It surveys the field of software cost estimation, including the major estimation techniques available, the state of the art in algorithmic cost models, and the outstanding research issues in software cost estimation. Reuse software engineering is based on guidelines and principles for reusing the existing software. A chunk of code is regularly organized using modules or namespaces into layers. However, The reuse of application frameworks and class libraries can improve the productivity in software development considerably. Reusability is often a required characteristic of platform software. Software reuse also sometimes referred as code reuse is the process of using existing software for the creation of new software. Discussions on reusability and reusable components are widespread among the practitioners of Software Engineering as well as the academia. Upon providing the relevant definitions and outlining the data and metrics provided as part of software development, we discuss how data mining techniques can be applied to software engineering data and illustrate the reuse potential that is provided in an integrated manner. Commercial-off-the-shelf is ready-made software. View Chapter 8 from CS 430 at University of Waterloo. In this paper, I ask three questions. .1. There have been several successful attempts in increasing the reusability of software components. Using a component model, that separates the communication and computation into distinct layers, enables us to secure the communication part of the system. If any required components are not available, they have to be built out of lower-level components. Terms like composition, interconnection, interaction, communication and interoperation are closely related. CS430 Applications Software Engineering Chapter 8 Reusability and Portability Instructor: Tian Kou 9/8/16 CS430 Applications Software Engineering CBR development experience is documented using software process, Software reuse is the process of implementing or updating software systems using existing software assets, resulting in a software quality increase, productivity and reducing time to market. Definition of reusability in the Definitions.net dictionary. Chapter 18Slide 7. Software reuse is difficult. A summary is presented of the current state of the art and recent trends in software engineering economics. Introduction Today, there are already a few companies which are specialized in developing CBR applications. The term applies to using something repeatedly for the same purpose or finding ways to repurpose things to make greater use of them. Incremental composition is defined to offer preservation of system behaviour and correctness of partial architecture at each incremental step. Finally, we evaluate the effectiveness of these tools using a known database benchmark. A heavy reliance on software reuse helped to "make the prototyping truly rapid". To use parts of one product in another product with a different function. Database automatic tuning tools are an essential class of database applications for database administrators (DBAs) and researchers. Examples of domains are airline reservation systems, software development tools, user interfaces and financial applications. In the context of software engineering, domains are application areas. Test Automation Frameworks and Code. code, documentation, design, testing, anything Is porting an example of reuse? legal issues may have to be considered, and Examples Software libraries. Let's explore this in detail. Reuse benefits 2. The development based on services in SOA supports the software reuse and maintenance better than the development based on individual classes in monolithic object-oriented software. Reference [6] defines software reuse as “the systematic use of existing software assets to construct new or modified assets.Software assets in this view may be source code or executables, design templates, freestanding Commercial-Off-The-Shelf (COTS) or Open Source Software (OSS) components, or entire software architectures and their components forming a product line (PL) or product family. This papers presents Orion-RE, a Component-Based Software Reengineering Environment that uses software reengineering and component-based development. Such components cannot be simply extracted from existing applications. The objective is to benefit from all the advantages of SOA when creating new SPVs. 1. Systematic reuse requires long-term, top-down management support because [FI94]: However, they do not suffice to make software reuse happen. The case study concerns how much reuse was done and how. Getting reusable components requires more effort. This can cause serious problems... techniques to rebuilt legacy systems, reusing their available documentation and knowledge embedded in the code. If these issues are not considered, software may appear to be reusable from design point of view, but will not be reused in practice. We envision an ideal scenario of software engineering as building applications by assembling high-level components. Software reuse has many technical and nontechnical aspects, for example, ad-hoc reuse, institutionalized reuse, black-box reuse, white-box reuse, source … Human readers need additional information which has to be provided in the documentation of a software system. Application engineering is software engineering with the systematic reuse of existing components and domain knowledge. Our proposed pattern for a generalised exogenous connector helps in specifying exogenous connectors with enough details that can be used for the implementation of these connectors. This seems logical for systems documentation of objectoriented software. This paper is about software engineering teaching experiences, held at both University of Pisa and Polytechnic of Torino. In case needed components are not available they have to be specified and provided by the component group. Our results show that the framework enabled instantiating useful self-tuning tools with a low effort by just extending well-defined framework hot-spots. However, interface descriptions of source code components (i.e., parts of the reuse manual) may be created in a literate manner for the reuse documentation as well. In the previous chapter we described the most important steps for the creation of software. Coping with the complexities of software development should involve sweating over the design specification, isolating critical functions, documenting the development process, commenting one's code, testing extensively both the individual components and the interworkings of the entire system, independently validating the product, and inclusion of backup systems. Commercial-off-the-shelf software components are ready-made components that can be reused for a new software. the unavailability of modular polyphase finite impulse response (FIR) structures that can avail the benefits of both software and hardware reuse restrict the overall performance gain of the systems. Furthermore, two types of module (Module-A and Module-B) are presented, and it is shown that a Jth order FIR filter can be realized by an interconnecting a suitable number of Module-A and Module-B in a systematic manner. The eighth edition is organized into 5 parts: RQ3: How can the programmers of an ecosystem react collectively to such events, or prepare for them? In this paper, we model and simulate the static/dynamic behaviour of sample exogenous connectors based on our proposed model. Requirements reuse is a matter of reusing much more than just plain lists of requirements. This level of design has been addressed in a number of ways including informal diagrams and descriptive terms, module interconnection languages, templates and frameworks for systems that serve the needs of specific domains, and formal models of component integration mechanisms. Software reuse and software components provide crucial contributions in this direction; this is the topic of Part III. This paper proposes a new software development process model that merges CBSE and MDD principles to facilitate software development. More recent work has addressed nontechnical factors: management, economics, culture and law [PF93]. The book Software Engineering with Reusable Components is intended for readers at universities as well as in industry. McIlroy introduced the concept of formal reuse through the software factory concept. Many of the problems we had to solve were caused by the inadequate support of reuse through the language we initially used. Many common... Design patterns. Our experience showed that it is not enough to use an object-oriented language to make reuse happen, but high-quality class libraries are essential to get the desired productivity improvements. This paper presents an overview of the INRECA methodology for building and maintaining CBR applications. The IBM® Rational® solution for systems and software engineering − the SSE platform − facilitates strategic reuse in large-scale product line development. Documentation requires mechanisms for systematic reuse similar to these for software. Several advances were made, including repositories, classification techniques, creation and distribution of reusable components, reuse support environments and corporate reuse programs. Test documentation can be used to help future stakeholders understand the rationale behind the testing effort. All of these approaches are applicable only in certain contexts and do not provide general solutions to software engineering problems, but they demonstrate that productivity can be increased considerably when special attention is paid to software composition. Identifying services by analyzing several SPVs allows to increase the reusability of identified services. In this thesis, I present the application of software engineering methods and knowledge to the development, maintenance, and evolution of Coq —an interactive proof assistant based on type theory— and its package ecosystem. Indeed, modern language-specific package managers have made it much easier to share reusable code and depend on components written by someone else (often by total strangers). Software is long known to be too complex to develop without adequate quality control. Proponents claim that objects and software components offer a more advanced form of reusability, although it has been tough to objectively measure and define levels or scores of reusability. • Discussions on reusability and reusable components are widespread among the practitioners of Software Engineering as well as the academia. Many nontechnical aspects have to be considered in order to improve systematic software reuse and to make it the normal way of software creation. Unlike VBXes, however, OLE controls can be built with 32-bit code; are based on COM (Common Object Model), a well-supported model; and are potentially portable beyond Windows and Win32 to the Mac OS. Now we deal with various attributes of components that allow us to better classify components. For example, if menus in a user interfaces are implemented using reusable components, all applications present the same menu formats to users. © 2008-2020 ResearchGate GmbH. A very common example of code reuse is the technique of using a software library. This is based on analyzing the commonality and the variability between SPVs to identify the implementation of reusable functionalities corresponding to cloned codes that can be packaged as reusable services. By using literate programs, we simultaneously measure reuse in source code and documentation.
