The database of RNA secondary structure elements
At the moment, there are many tools that provide object approach to application development. This is the fact that the object-oriented paradigm is dominant in the development of new applications for any subject domains. Object-oriented approach is increasingly used in the implementation of database applications. The existence of their own strengths and weaknesses of each instrument, their main goal-to provide developers all the benefits of object-oriented paradigm for implementation of database applications. This paper provides a detailed overview of existing works and presents the unified testing model which is used to demonstrate different methods of presenting structural models in database applications. In last section the conclusions of the work and made suggestions for further development is given. This paper is the result of years of research and is based on numerous articles published in the Proceedings of the International Scientific and Practical Conference "Object Systems" (objectsystems.ru).
