* historical development of databases and databases management systems
Part 2: Relational databases: Model and Languages.
* Relational model
* Relational Algebra
* Relational Calculus
* SQL Language
Part 3: Database Design
* Design techniques and models.
* Conceptual Design.
* Entity-Relation (Er and Enhanced Entity-Relation (EER) model.
* Logical Design: algorithms for mapping ER and EER models into relational models.
* Physical Design: Indices
* Normalization: functional dependences, first, second, third and Boyce-Code normal form.Normalization algorithms.
Part 4: Database technology
* transactions, concurrency and security concepts.
Finally, the program for the lab. will cover the following topics:
