Learning outcomes of the course unit

The course familiarises students with theoretical aspects of database application design and its implementation in MS Access including programming in SQL and Visual Basic. They will be able to create an application for an efficient management of large scale data structures.

Prerequisites

Successful completion of the course "Database Systems" is conditional on basic knowledge of algoritmization and Pascal (or Delphi) language.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

The course-unit credit is awarded on condition of having implemented a nontrivial database application in MS Access using Visual Basic and SQL. The exam has a written form and tests students’ knowledge of database design, relational algebra, SQL and programming in Visual Basic.

Aims

The course aims to acquaint the students with basic database technologies for an efficient design and management of applications with large data structures in Microsoft Access 2003 environment using SQL (Structured Query Language) and Visual Basic.

Specification of controlled education, way of implementation and compensation for absences

Since the attendance at seminars is required, it will be checked systematically by the teacher supervising the seminar. If a student misses a seminar, an excused absence can be compensated for via make-up topics of exercises.

Recommended optional programme components
