Course abstract

The aim of the study course is to aquire knowledge about tools and technologies that allow to manage large and specific data sets.
Studies of database management system extended functionality are performed. Application of data retrieval language specific constructions, PL/SQL extension, procedure and function creation are discussed and practically applied. Such topics as query optimization, storage of various types of data are included. Students gain practical knowledge about work with large database management system Oracle Database.

Learning outcomes and their assessment

Knows about large database architecture and application possibilities of Structured Query Language extensions.
Have skills about the development of large databases, data storage and retrieval, evaluation of database architecture and application of Structured Query Language extensions for data retrieval are acquired.
Students develop competences of data analysis, choosing and participating in discussions about the technological solution for storage and retrieval of large amounts of data, working in groups or individually.
Learning outcomes are assessed with three tests.

Requirements for awarding credit points

Students receive awarding credit points after they successfully pass exam. To access exam, students need to receive positive mark in tests which is calculated as an average mark from three tests and complete assigned practicals.
Tests topics:
2.PL/SQL procedure and function programming
3.Trigger programming and dynamic SQL.
Theory test main topics relate to description of SQL extension description with focus on PL/SQL and SQL tuning.

Description of the organization and tasks of students’ independent work

There are no individual assignments scheduled during the course.

Criteria for Evaluating Learning Outcomes

To access exam, students need to receive positive mark in tests which is calculated as an average mark from three tests. During exam students complete written test (part 1) which includes questions from semester topics. After first part, students receive practical assignment in classroom which they complete and submit within given time.
