Anotace:

The course is devoted to selected problems of database systems construction as well as to advanced database technologies. Processes of data and function analysis are discussed in detail. Design of conceptual schema in binary E-R model, design of data flow diagrams, and a methodology for synthesis of both methods are presented as well. Then the transition from conceptual to database level of a design is explained. Fundamentals of object-oriented and object-relational technologies are also included. Techniques of query optimisation in relational DBMS are studied in detail. Recent approaches to data distribution and data warehouses construction are also presented. Finally, basics of text databases are explained.
