deciding on the design of the user interface.

3. Rapid constructionbuild a prototype and demonstrate it to the user.

4. Cutover Convert from prototype

to final product.

Fast Rapid Application Development Secure Helps developer avoiding

security concerns Scalable Quick and flexible scaling. Provides both admin and client control Features ORM i.e. Object Relational

Mapping Encapsulates the code needed to

manipulate data Saves from SQL Prevents from reinventing the
