IDS Acad. year 2020/2021 Summer semester 5 credits
Fundamentals of database systems (DBS). Conceptual Modelling. The relational model. Relational database design from a conceptual model. Normalization-based design of a relational database. SQL language. Transaction processing. DBS architectures: client/server, multi-tier architectures, distributed DBS. Introduction to database administration: data security and integrity, introduction to physical database design, performance optimization, database recovery, concurrency control. Trends in database technology. The project consists in designing the structure of a relational database and programming SQL scripts to create the database, querying data in it, database triggers, and stored procedures.
Language of instruction
Subject specific learning outcomes and competences
- Student is able to develop conceptual models of an application domain for database applications.
- He/she can develop database applications for relational databases, knows the standard database language for relational databases SQL, and has experience with some integrated development environment for database applications. and have knowledge of relational database management system fundamentals.
- He/she receives basic competencies for database administrator's work like user account creation, access rights assignment and performance tuning.
- Student acquaints with fundamentals of some important functions of advanced database system like transactional processing, concurrency and recovery.
- Student acquaints with basic English terminology in the subject.
Generic learning outcomes and competences
The student will learn how to analyze a given problem in a small team and he/she will learn to design and implement a solution of the problem individually. He/she learns to present and defend both partial and final results of the project.
Mastering fundamentals of relational database theory and skill in using database technology at a level required for database design, development of database applications and database administration.
Why is the course taught
Since the 1960s, when data intensive applications and systems have been developed and used, typically information systems and their parts, database systems have been used to store data. Database technologies have evolved rapidly and are widely used today. It is, therefore, necessary for students to acquire competencies and skills in this field. This subject is focused on the basics of database technologies, namely relational databases that play a key role here.
Prerequisite kwnowledge and skills
The sets, relations and mappings. The elementary notions of the graph theory. Basics of hashing and tree-based search. Basic steps of software development. Rudiments of programming and data modelling.
