Draveliqor is an educational project focused on database concepts and structured information systems. Our courses explore relational databases, data modeling, query logic, transactions, indexing, data preservation, and database architecture through detailed written materials and practical exercises.

Not every course requires previous experience. Our introductory materials explain foundational concepts, while later courses examine more detailed technical subjects. Each course description outlines the topics covered and the recommended background.

Our collection contains ten courses arranged in a progressive learning sequence. Each course focuses on a particular area of database study and includes organized modules, technical explanations, examples, and review activities.

Our coursebooks contain detailed written lessons, database examples, explanatory diagrams, practical exercises, and supporting reference materials. Certain courses also include extended workshops, design challenges, and worked solutions.
