Database Systems and Cloud Storages (FSI-VDC-K)

Academic year 2021/2022
Supervisor: prof. RNDr. Ing. Miloš Šeda, Ph.D.  
Supervising institute: ÚAI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The course aims to acquaint the students with basic database technologies for an efficient design and management of applications with large data structures in web environment.
Learning outcomes and competences:
The course familiarises students with theoretical aspects of database application design and its implementation in web environment including programming in PHP and MySQL. They will be able to create an application for an efficient management of large scale data structures and they also will learn to use cloud services.
Prerequisites:
Successful completion of the course "Database Systems" is conditional on basic knowledge of algoritmization.
Course contents:
The course provides an introduction to DBS.
It deals with the following topics:
Data processing, redundancy, inconsistency, integrity, security, data sharing.
Index-sequential organisation. Relationship integrity constraints.
DBS architecture, data models. Entity-relationship model, relational algebra.
MySQL Workbench.
Theoretical fundamentals of information system design. Functional dependencies, normal forms, decomposition theorem.
Structured Query Language (SQL).
Web databases. HTML, PHP and MySQL.
Data security.
Clouds and grids.
NoSQL databases.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
The course-unit credit is awarded on condition of having implemented a nontrivial database application in HTML/PHP/MySQL. The exam has a written form and tests knowledge of students in database design, relational algebra, SQL, and programming in HTML/PHP/MySQL environment.
Controlled participation in lessons:
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.
Type of course unit:
    Guided consultation in combined form of studies  1 × 17 hrs. compulsory
