Modeling Systems Using Design Patterns

The possibility of the re-use of the design patterns brings into patterns more than it might seem. We use design patterns in method named “pure design patterns phase”. In described method we seek to take advantage of design patterns composition for complex solution of closer problems. We modified standard software development process with use of special phase, which by using design patterns as elementary modeling unit purport to describe majority of solution. In this paper we describe basic notation for model in this phase. Based on example with patterns Composite and Iterator we define general relation between any two patterns.
