Comparison of the possibilities of object-oriented and relational databases

This thesis presents the theoretical description of relational and object-oriented databases, including the underlying basic concepts. The paper briefly describes the specific database systems according to various categories. Work tries to look at all the facts in general terms therefore does part of it explain other database principles. On the example of a small library the paper displays the strengths and weaknesses of both principles. Later the paper describes more thoroughly the Caché database system, which can be addressed by both principles. The difference between object and relational approach is then shown in this environment. The goal is therefore to provide side information about the various principles, define the differences in categories and then show the problems on a practical example. Further clarify the specific database system and try to demonstrate the previously defined categories in this environment. One's own contribution to the treated subject can be found in different approaches of the specific models, the comparison of the two approaches on particular examples, the examination of the selected database system and conducting a comparison of the principles in the Caché environment.
