4.Current Implementation Features 4.4.Database General Considerations
We consider for this project 2 types of databases:
• “Socrates” database that is used to hold the common data for the entire project
• A database for each course, containing all the information about the course

4.Current Implementation Features 4.4.Database Structure – course databases
Table from the Java course
database
The course database holds•the structure of the course•the questions and answers related to the chapters, subchapters and paragraphs of the course and to the keywords of the course, •each learner’s path through the course and the path suggested by the LPET•users performances during the tests
The information from the database is used to dinamically generate the navigation menu of the course.
