Relational databases, object oriented and object relational databases, and semistructured databases are examined with regard to different aspects. All database types have advantages and disadvantages. Advanced business logic and multimedia support set new requirements of database functionality. Semistructured databases (web databases) are becoming more and more common, especially when combined with other Internet functionality and the Semantic Web.
This course deals with the different areas of applications of databases, as well as aspects of the different models, languages, and database management systems.
Theory about relational databases, object databases and semistructured (web) databases.
Areas of application.
Comparison of database models.
Comparison of database languages for:
- relational databases: relational algebra, relational calculus, SQL
- object databases: OQL, ODQL
- web databases: Lorel, XQuery, DB2XMLQL
Embedded database languages (with Java as the host language).
