ABSTRACT
Integration is one of the most promising or important tasks for Component-Based Development. The Commercial off the Shelf (COTS) Component is selected to satisfy the system requirements and after selection these components should be integrated to form the required system. This chapter provides a model for estimating the efforts invested in integrating these components. COTS integration is all about binding different components together to form a system. Many customers think that the entire system may be divided into modules and one can purchase modules. The system should be implemented in such a way that it helps hospital staff to record data in a better manner and can retrieve data in several ways. Databases and the functionality of Data Recording Systems should be integrated with a production system score. These systems do not even have a common communication protocol.
