Abstract
The paper presents a unified model for testing tools for object-oriented application development. Based the available papers were identified shortcomings of existing work and identified the following optimal criteria, which shall comply the resulting model: 1. To deep inheritance hierarchies 2. To presents of multiple inheritance hierarchies 3. To presents of abstract classes in the hierarchy 4. To presents of multiple (n-ary) associations 5. To presents of associations with attributes 6. To presents of a composition between classes 7. To presents of recursive associations 8. To presents of associations between classes belonging to the same inheritance hierarchy 9. To presents of association classes 10. To presents between the association class and other classes 11 To presents enumerations in model With a unified graphical language UML class diagram unified model testing. The paper we verified compliance with the resulting implementation of the selected criteria was presented. Currentlythe implementation of applications using object-oriented programming languages and relational databases. To overcome the object-relational mismatch it is necessary to implement object-related mapping patterns presents. The paper presents three methods used to represent the class hierarchy highlighted the advantages and disadvantages of each method. For test the feasibility a unified model chosen development environment SharpArchitect RAD Studio which is designed object applications in C# and are implementing a relational database. The paper presents the developed object model in the form a class diagram showing the interfaces and inheritance relations diagram containing all the tables and columns the resulting database. In the conclusion recommendations on the areas for further development work and identified the need of implement a unified model with other approaches proposed by the authors was used.

Summary
At the moment there are many tools provide object approach to application development. Despite the existence of their own advantages and disadvantages the main goal is provide the advantages of the developer of object-oriented paradigm. The paper are describes in detail the unified model test tools development of objectoriented applications for demonstration, graphical Unified Modeling Language which used. The practical implementation of the model is demonstrated by the use of classical methods (patterns) object-relational mapping (ORM) in the tool, developed the author. The object model is put into a relational database environment. This approach is most justified from the point of view the author, because the RDBMS is the most popular type of database management systems
