12. Creating an INDEX in SQL.
13. Imagination, creating and using VIEW.
14. SQL Creating functions in SQL. Creating triggers in SQL
15. programming languages and a database.

V. Independent learning and independent work

in-depth study
of individual topics and sections of the subject . Independent work
must be completed in the form of an abstract,
with a conclusion and a list of used literature . It is recommended to obtain additional information from the Internet (scientific articles not related to this program
, author's notes from blogs, artistic materials)
for independent work .

methods in the educational process
is independently chosen by the student. The organization of the student's independent
learning is carried out systematically, that is, continuously and coherently . The student must
independently
prepare for the next new topic in order to consolidate the theoretical knowledge he has acquired .

For independent learning recommended topics:

1. Object-oriented database.
2. Codd's relational algebra. Relational calculus.
3. Object database. Design, processing and research.
4. NoSQL database and its basic principles.
5. Technological perspectives in database formation.
6. Data model in database construction in practice.
7. ORACLE database.
8. Database system architecture.
9. Relational data model. Relationships in a database.
10. SQL queries in transaction management.
11. Database administration and security design.
12. Open Database Connectivity (ODBC) interface.
13. Describing a database in XML

V I. Learning outcomes:

The student should know:

-Have an idea of dividing the subject area and creating its model ;

-Methods for describing the model of the subject area;

-Know and be able to select database management systems and create databases on personal computers and use them;

VII. Educational technologies and methods:

1. Lectures.
2. Interactive case studies
3. Working in groups (Min/Max)
4. Presentation
5. Logical thinking questions and answers

VIII. Requirements for obtaining loans:

They are required to submit the tasks and assignments assigned to the system in the form of practical work, independent work, current, and intermediate control within the specified time frame. Final control work in the form of a test or written test is submitted in the above-mentioned system or, if it is planned to be submitted in another system, in that system.

Based on the established procedure, students' participation throughout the course, as well as the results of the final written work on theoretical and practical subjects, will be assessed.

The assessment is distributed as follows:

• Lectures – 25%;.
• Practical training – 25%;
• Final control – 50%.

Theoretical assessment:

During the course, there will be 1 midterm exam, independent learning, and active participation in practical exercises. During midterm exams, three questions are asked and students provide written answers. During active participation in practical exercises, students are assessed based on factors such as timely completion of assigned tasks and assignments, answering questions asked by teachers, and the correct approach to the topic.
