Zakres tematyczny

Lecture

• Basic concepts of the relational data model.
• Operations on relations (union, intersection, difference and complement; projection, selection and join, division).
• Functional dependencies and Armstrong axioms.
• Relational schemas.
• Decomposition of relational schemas (without data loss, without loss of functional relationships and into independent components).
• The normalization process of relational schemas (First Normal Form, Second Normal Form, Third Normal Form, Boyce–Codd Normal Form, 4NF, 5NF).
• Multivalued dependencies.
• The set of axioms for multivalued dependencies.
• Optimization of the sets of functional dependencies.
• SQL language:
  • Data Definition Language - DDL.
  • Data Manipulation Language - DML.
  • Data Control language - DCL.
• Database design (diagrams: DFD, ERD, generating the database schema).

Laboratory

• Applications of the SQL language.
• Data types, expressions and operators, conditions, functions, procedures.
• SELECT statement: inner and outer join, simple and correlated subqueries, grouping and aggregate functions, set operators UNION, MINUS, INTERSECT.
• Defining database structures: domains, tables, views, indexes, sequences / generators, triggers, integrity constraints.
• Database user management and transaction control.
• The use of selected computer CASE tools to generate a simple database schema.

Warunki zaliczenia

Lecture: an exam consisting of two parts: written and oral, the condition for the oral part is to obtain at least 30% of points in the written part, obtaining 50% of points in the written part guarantees a positive mark, without the need to take the oral part. The condition for taking the exam is obtaining a positive grade from the classes.

Laboratory: the grade consists of points from four tests writen in the semester or from points from a test covering the entire material (80% of the grade) and students' activity during classes (20% of the grade).

The final grade for the course is the arithmetic mean of grades from the lecture and laboratory. The necessary condition for obtaining a positive final grade is obtaining positive grades from the lecture and the laboratory.
