In project management on creation of program application, specialists from different subject areas are involved, who include their contributions, for instance, UI/UX designers who create mock-ups of the future application or developers who write the code according to the prototype. The design conception may go beyond the possibilities of interpreting it from a technical point of view of implementation. The realization of such idea could not to be able to collect on only one defined program platform or language, and accordingly the problem is appeared. To eliminate semantic gap between the designers’ concepts and opportunity of program developers in technical affordance, released methodology, Model Driven Architecture (MDA), which is, on the one hand, a concept for implementation of software, on the other hand a standard. In paper, considerate the MDA and its transformation levels with determine a pragmatical semantics of mapping, reasons of chosen a class diagram as model of transformation and Java language for code generation.
