Summary:
| |
Successful graduation of the course requires knowledge and skills, that students have acquired in course Database systems and Database systems II (relational model, object-relational model, database optimiser). Since these courses cover the SQL language in a short overview and haphazardly, a thorough treatment of most features of the SQL language is given here, particularly according to the standards SQL:1999 and SQL:2003. As a background of these standards, the object-relational data model is discussed in detail. An attention is devoted to recursion in SQL as well as to selected parts of the SQL/MM standard. The last part o lectures is devoted to temporal extensions of SQL, to possibilities of SQL for OLAP, and to partial integration of SQL and the XML language.
