Obtaining of elements of UML class diagram from initial information about problem domain

The Model Driven Architecture (MDA) is frequently used approach to software development. Basic conception of MDA is splitting of software development by levels of abstraction, where every level is presented with separate model - Computation Independent, Platform Independent, Platform Specific Models and code. The construction of central component of Platform Independent Model - system static structure in form of Unified Modeling Language (UML) class diagram is discussed in the paper. A set of approaches proposes the way for construction of UML class diagram. Different researchers try to find the possibility to obtain elements of class diagram in the formal way. This paper describes the method of obtaining of elements of class diagram from initial knowledge about the problem domain, which is described with interrelated business process and concept model. The proposed method defines main elements of class diagram, such as class name, class attribute, class operation, relationships among classes. Formal definition of these elements allows to avoid mistakes in the software analysis and design stage. It is very important to obtain correct model on this stage, as the design model is a base of future software.
