Design Method -Summary

Interface design encompasses external and internal program interfaces and the design of the user interface. External and Internal interface design is guided through information obtained from the analysis model.A variety of implementation tools are used to established a prototype for evaluation by the user.A group of generic design guidelines govern general interaction information display, data entry.

Design notation coupled with structured programming concepts enables the designer to represent process detail in a manner that facilitates translation to code. The Graphical, tabular and textual notations are available.Data structure is established program architecture is established modules are described and interfaces are  established.  That blueprint for implementation forms the basis for all subsequent software engineering work.
