Requirements for data base management systems?

Identify functional prototype activity is to identify the functionalities that would be in the prototype of current iteration. Recall that both, analysis and coding are done; prototypes are built, and the experiences gained from them are used in improving the analysis models (based also on updated prioritized requirements list and updated risk log). The built prototypes are not to be entirely discarded, but gradually steered towards such quality that they can be included in the final system. Agree schedule is to determine when and how the prototyping will be implemented; it extends the scope to the available timetable and prototyping plan. And since testing is implemented throughout the whole process, it’s also an essential part of this phase, and therefore it is included in the Review Prototype activity right after the functional prototype is built and the test record will eventually be used in the review prototype process and generates the review document. Below is the process-data diagram of Functional Model Iteration stage.
