Modern business processes depend on data, and most companies use complex database management systems (DBMS) for storing and processing it. The development of database technologies and competitive pressure have led to the creation of powerful and complex systems, the use of which requires deep understanding. Errors in working with such systems can be costly. This course provides fundamental knowledge about the operation of DBMS, allowing for informed decision-making in the design and use of relational databases.
During the course exercises, you will create a simple relational database management system. The exercises are designed to allow you to solve tasks independently, referring to video guides and additional explanations only when necessary. Instead of a rigid definition of exercise completion, you are provided with flexibility: you can focus on core tasks and interesting additional goals. The course also includes seminars recorded with participants from CS Primer, which cover complex conceptual aspects that are difficult to understand in an exercise format. It is recommended to attend the seminars after studying the corresponding course module.
