| Course abstract | |
| The aim of the study course is to learn data base model creation basics technological implementations. Studies of basic functionality of database technology are performed. Basics of database design and data models are discussed. Students learn to develop and normalize data tables. Table relationships and basics of data retrieval are learned. Data retrieval from tables with structured query language are discussed and practically applied. Students gain practical knowledge about database management system PostgreSQL and individually develop semester assignment. | |
| Learning outcomes and their assessment | |
| Students gain knowledge about general concepts of database technology and Structured Query Language SQL. Practical skills about the development of databases for storage of various data types, examination of data table design, elimination of design inconsistencies and retrieval of data with Structured Query Language are acquired. Students develop competences of group or individual data analysis, choosing and taking part in discussions about the technological solution for data storage and retrieval. | |

| Requirements for awarding credit points | |
| To receive credit points students must submit and receive positive grade for homework as well as all test average mark must be positive.
Tests: 1. Development of data base models. 2. Data base model development in data base management system 3. Theoretical test about all topics covered in the lectures. |
|
| Description of the organization and tasks of students’ independent work | |
| Students need to individually complete homework which includes development of a data base in database management system, including documentation of the data base. For development of homework 1 month is given since definition of the assignment. | |
| Criteria for Evaluating Learning Outcomes | |
| Semester final test mark is calculated as an average mark based on student scores gathered from homework and semester tests. Practicals must be submitted and graded positive. | |
