Extended program | The program for the theoretical part of the course is developed in four parts: Part 1: Introduction to databases and database management systems * 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: * The Postgres DBMS * SQL language: schema definition, constraints, queries, and views. Basic and advanced instructions. Usage of the DBMS PostGres for realizing a database. * SQL programming techniques. Trigger and active databases. Embedded SQL. JDBC. |
