Anotace:

Students get acquainted with the architecture of the database engine and typical user roles. They learn to design the structure of a smaller data store (including integrity constraints) using a conceptual model and then implement them in a relational database engine. They get acquainted with the SQL language and also with its theoretical basis - relational database model. They will get acquainted with the principles of relational database schema normalization. They understand the basic concepts of transaction processing and control of parallel user access to a single data source. At the end of the course, students will be introduced to alternative nonrelational database models.

Požadavky:

Entry knowledge: Common user-level knowledge of Unix/Linux and MS Windows operating systems, ability to describe a solution to a problem algorithmically, and elementary knowledge of algebra and logic are expected. Active knowledge of a specific programming language is not required.

Osnova přednášek:

1. Basic principles of database systems, architectures of database management systems.

2. Conceptual, database, and physical level of view of data.

3. Conceptual data model. Basic constructs, expression of integrity constraints.

4. Relational data model. Relation, attributes, domains, relational database schema, relational algebra.

5. Introduction to the SQL language: basics of the SELECT statement, basics of the SQL DDL.

6. Design of a relational scheme by direct transformation from a conceptual scheme.

7. The SQL language - advanced querying: aggregation, nested queries, set operations.

8. The SQL language: parts DCL, DML, TCL.

9. Transactions, error recovery, parallel access coordination, data protection.

10. Functional dependencies, normal forms of relations, normalization of a relational scheme by decomposition.

11. Physical level of view of data. Indexes and their use in relational databases. Basics of SQL query optimization.

12. Nonrelational database models. Trends in databases.

13. Access of applications to a (relational) database. Introduction to the concept of software engineering.

Cíle studia:

After completing the module, students will be able to design and implement small databases and work with them effectively using the SQL language. Today, knowledge of (relational) databases is a necessary qualification, not just for programmers of information systems and creators of www applications, but for practically all informatics professionals. The module provides hands-on experience with databases that can be directly used in a wide range of situations, as well as theoretical foundations for subsequent modules, such as Database systems administration or specialized database-oriented modules (SQL, Database systems 2) in the second cycle degree programme.
