Web Services and Reuse

When programmers develop code, they break large complex operations into smaller, more manageable tasks. Programmers then implement the well-defined tasks as functions. Ideally, each function should perform only one task. In this way, programmers can often reuse the function code in other programs, which saves development and testing time and ultimately reduces development costs. A common rule of programming is not to “reinvent the wheel,” which means that if another programmer has written code that performs the task that your program needs, you should reuse that code.

Web services contain functions that perform specific tasks. Normally, the web service’s functions will perform key tasks that many programs need. As a result, web services typically have a high degree of reuse.
