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:
To deep inheritance hierarchies
To presents of multiple inheritance hierarchies
To presents of abstract classes in the hierarchy
To presents of multiple (n-ary) associations
To presents of associations with attributes
To presents of a composition between classes
To presents of recursive associations
To presents of associations between classes belonging to the same inheritance hierarchy
To presents of association classes
To presents between the association class and other classes
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.
Currently the 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.
