Comparison of Properties and Performance of Object Oriented Databases

In this thesis, the reader learns basic models, which are use for storing data in database sys- tems. Next I describe a way, how to store objects in Java Language and explain expressions like object-relational mapping, reflection and introspection. After that, I will introdice some of existing implementation, which are use for storing objects in Java. Next I will explain testing methodology and make benchmarks of various implementation. In the end I will analyze a results of these benchmarks
