Using PowerDesigner data flow diagram can be produced, the concept of data models, physical data model and can generate a variety of client development tool applications, but also for data storage structure of the production model, the team can also control design model. It can be with many popular database design software, such as : PowerBuilder, Delphi, VB, such as the use of line to shorten development time and allowing the system to optimize the design.
