The aim of this subject is to introduce students to the problems of database systems, their theories and principles of database design. The course has several views on database technology, the main emphasis is on data modeling and data analysis.
The course deals with various problems with access to data architecture, relational data model, ER model, normalization, data warehousing, distributed databases and knowledge bases. In the practical part, students practice their theoretical knowledge of designing and implementing database transformations of data models into relational database schema based on SQL standards.
The course is also familiar with the basic operations manager database servers and their users access and other services, security and automatic data backup.
