The reader will learn the syntax of relational algebra, its rules and function. He's being briefly introduced to SQL and possibilities of its use. Part of this work is description of translation relational algebra expressions and description of implementation design on selected database system. Thesis further describes functions of implemented application and contains description of its realization. The last part is about the application testing and the results are presented. Implemented application is compared with similar already existing applications.
