The goal of this course if to teach students the most commonly used techniques in developing data-driven and backend systems. Students will learn various methods for implementing systems built on data bases, typical solutions and techniques in the data access and business logic layers. The course presents the usage of various data base management systems in complex software development scenarios, and details the processes and solutions used by modern data managing (backend) applications.

Obtainable knowledge:
By completing the course, students are familiarized with the most commonly used data base engines (Microsoft SQL Server and MongoDB), their structure and operation, writing efficient SQL queries, optimizing them, handling transactions, locks, the proper usage of isolation levels, and server side programming techniques (stored procedures, triggers). Various data access libraries are presented (including ADO.NET), as well as commonly used ORM frameworks (such as Entity Framework and JPA).   The course presents serialization techniques of server-side objects (XML, JSON), and protocols for accessing such objects remotely (Web Service, REST), including the software environments (like ASP.NET Core Web API).

4	Advanced SQL language, data base server-side programming (Microsoft SQL Server platform, T-SQL language, stored procedures and triggers).
5	NoSQL data bases, document storage in NoSQL data bases; MongoDB platform, simple operations in MongoDB.
6	Queries and their efficiency in Microsoft SQL Server SQL Server. Execution plans and query optimization.
7	Data dictionaries. Semi-structured data (XML, JSON) storage and handling.
8	Data access layer, object-relational mapping, design patterns in the data access layer (repository).
9	Object relational mapping frameworksin .NET, ADO.NET, Entity Framework and Linq to Entity Framework.
10	Object relation frameworks in Java: JPA and QueryDSL
11	Business logic in Java: JavaEE, Spring, SpringData

During the seminars, held in computer laboratories, students will solve tasks in connection to the lectures:

During the seminars, held in computer laboratories, students will solve tasks in connection to the lectures:

During the semester

1.   One midterm exam

2.   The seminars provide the opportunity to put the gained knowledge into practice. Students must be present at the seminars and work with the instructor.

During the semester there are mandatory homework assignments.  

In order to receive signature for the course, students must:

o    must pass the midterm exam, and

o    the student must be present at the seminars as required by the Code of Study and Exams.

 In the exam period:

Written exam.

Final grade is calculated by summing the exam points and the extra points obtained during the semester. The final grade is: 0-40p fail, 41-55p pass, 56-70p satisfactory, 71-85p good, 86-100p very good.

The mid-term test can be repeated once during the semester.

There are no repeated seminars. However, absense from seminars is allowed with proof of a good reason, such as illness (with official record of it presented).

Homeworks cannot be repeated.

Exams may be repeated as the Code of Studies allows it.
