1. INTRODUCTION
Encouraging software reuse improves the dependability of a product, as a reusable software unit is tried and tested. It reduces the risk of developing a large component from scratch, as it is easy to estimate the cost of using a large reusable software unit. Apart from ensuring quick product delivery, it enables the architects to reuse patterns and architectures suitable for particular situation, and the developers to use a set of program libraries, which eventually reduce the time for development.
Although, the idea of reusing a software unit seems to do more good than harm, it carries along with it certain drawbacks. The cost of maintaining a reusable unit will be high, if the system is subject to frequent changes. Tools used by the developers may not support the reusable component library, thereby making it extremely difficult to develop. Populating and maintaining an enormous library to exploit component reuse becomes expensive. Apart from these aspects, the very notion of identifying a reusable unit, comprehending the working process of a reusable unit and utilizing the unit in a new environment is itself a challenge.
2. THE REUSE ARENA
Over the past few decades, many techniques have been proposed and adopted to augment software reuse. These approaches harness the idea of reuse in similar application domains because the core functionality of such systems can be implemented using reusable software units. Every approach is suitable for few scenarios and it is the responsibility of the management and technical team to identify the suitability of the approach in developing a reusable software unit or exploiting the use of a software unit in developing a product.

...e pool had lesser number of LOC (lines of code) and few other components though complex, were implemented using sound reuse design principles such as well-defined interface, clarity and understandability and documentation. Also, these components were implemented using well known frameworks such as Model-View-Controller (MVC) in java. The results gave an interesting insight into the relationship between complex software units implemented with good design principles and the ease of reuse. It was observed that components that were implemented with good design principles and that were build using standardized architectural styles and frameworks yielded a higher reusability quotient. Hence, in order to increase the reusability quotient of a software unit, it is necessary that it implements sound design principles and a proven reuse oriented software engineering approach.
rapidly chooses how to convey the set of uses and framework servers over different machines in the cloud. Large portions of the conventional parallel applications for the most part utilize an altered number of strings on the other hand procedures characterized as a parameter toward the begin of the application. The choice for the number of strings is frequently chosen by the client in a push to completely use the parallel assets of the framework or to take care of top demand of a specific administration. fos utilizes the duplicated server model which permits extra transforming units to be alterably included amid runtime permitting the framework to attain a finer use for element workloads and lightening the client from such
Open source software development is taking place all over the world where part of the community develops individual modules, becoming necessary to establish standards and common definitions for open source software. These standards are established to define interaction between modules to insure interoperability of software. Software components which follow specific open standards can be replaced with other standard-compliant product, which allows the user more freedom to choose the component best suited to his needs and is not bound to a particular product, as with commercial software (Chauhan)
In this section, we consider perspectives to increase the inclusivity of software products as well as the skills required by personnel involved in the design and development of software.
Standardize procedures and project management. E.g. use the same language or coding and decoding of software.
Before we begin, we must first ascertain the difference between acceptable reuse of code and theft. The reuse of code can fall in too both categories, However this can be perfectly legal to do, it can also be considered theft. The reuse of your own code creations is just fine, but the use of third-party code may not be the case. There is a difference between the reuse of code and the theft of intellectual property.
A framework is a set of classes that supports reuse at larger granularity. It defines an object-oriented abstract design for a particular kind of application which enables not only source code reuse, but also design reuse [Johnson & Foote, 1988]. The framework abstract structure can be filled with classes from its own library or application-specific ones, providing flexibility for the developer to adapt its behavior to each application. Besides flexibility, a good framework also increases the team productivity and makes application maintenance easier [Fayad et al. 1999].
Hardware, software, support and maintenance costs grow each year with multiple systems in each local region running different types of software and hardware. The application and hardware support teams are larger than could be possible with one integrated solution.
The reason that I have chosen to do this question is that I want to discover whether there is a viable solution for a company as large as Microsoft to increase their profit margins or if Microsoft 's size prevents them from further increasing their profits. It is important to find out as if there is a clear way to increase profits it may be possible for other similar firms to also increase their profits. Since Microsoft 's establishment in April 1975 they have grown into a monopoly within the technology market, bringing huge innovation to the technology market. Successes such as the ‘Windows’ Operating system along with further inventions such as the ‘Xbox’ have allowed Microsoft to become diverse within their product portfolio
While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
This paper has the intention to explain what Rational Unified Process (RUP) is like an IBM product and a CASE tool. After is explained what phases it has, what are the most common extensions thus what are its workflows more used. The Rational Unified Process (RUP) is a software design method created by the Rational Software Corporation and now is part of IBM developer software. This paper describes how to deploy software effectively. The Rational Unified Process (RUP) use commercially proven techniques, and is a heavy weight process, and hence particularly applicable to larger software development teams working on large projects.
Extra advantages our company can benefit from are the variety of modules that support various functions, like accounting, distribution, human resources (HR), materials planning, manufacturing, marketing, order entry, and warehousing. When a user from any department enters information into a module it will automatically update throughout the system. Modules can be adopted to suit the needs of every department and simplify their processes as well as share the attained information throughout our business. Additions like CRM (customer relationship management) and a SCM (supply chain management) ...
Michael Duell of AG Communication Systems presented a novel approach that may be adapted to introduce design patterns. He compares the theory behind design patterns to a real world model, illustrating the workings of the pattern implementation by giving trivial examples that a developer may be better able to relate to than the formal explanations offered by GoF or Holub for example.
The Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The key is to organize the design process in a way that clients, analysts, programmers and other involved in system development can understand and agree on. The UML provides the organization. The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thin to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.
obect orientated programming has many advantages, one of these is the fact that the objects created : Jeffrey L. Popyack (2012) "can easily be reused in other programs." The Saylor Foundation also states that object orientated programming allows “Improved software-development productivity" and "Improved software maintainability” through the modular structure of the development.
The lack of an enterprise part numbering system is a major deficiency in our company. The data from our Product Lifecycle Management (PLM) systems indicates that our engineers located in various geographical design locations design on an average 300 parts every day. An enterprise Part Numbering System (PNS) will greatly improve the management of the constantly changing portfolio of parts in our company. It will have a far reaching impact in every aspect of our operations including supply chain management, inventory management, part number duplication, design duplication effort, design management, change management and components reuse.
