DESIGNING CODE LEVEL REUSABLE SOFTWARE COMPONENTS

The basic idea behind building Reusable software components is to design interchangeable parts from other industries to the software field of construction. A reuse library or component reuse repository organizes stores and manages reusable components. The biggest advantage of the building reusable software components is that it reduces the time and energy in developing any software. Frameworks provides a standard working system through which user 's main focus is on developing desired modules instead of developing lower level details. By using this facility the software developers can spend more time in developing the requirement of software, rather than preparing the tools of application development. Framework is set of reusable software program that forms the basis for an application. Frameworks help the programmers to build the application quickly .At its best code reuse is accomplished through the sharing of common classes and/or collections of functions, frameworks and procedures. This paper describes how to build the code level reusable components and how to design code level components. Finally providing coding guidelines, standards and best practices used for creating reusable code level components and guidelines and best practices for making configurable and easy to use.
