Re: Implementing "Create Course"

["Alexey Parshin" <alexeyp@gmail.com>]

Course is defined in study_course table. The difference between TLT and another topic is in connection to study_course and course_server (through server_to_tlt).
May be we don't need study_course table at all? Then we have just TLT, class, and connector between them. There would be only one problem after that: If new version of TLT is created, do we keep class connected to the old one?

Course-related functions are defined in study_course.sql. The course is created during TLT creation.

Yep, this is confusing. TLT is just another topic, authors should have an
ability to create new version of it.
However, as I understand, Course is on top of Topic, not included in
Topic. It should be just a snapshot of the whatever TLT version was used
during initial Course creation. If new TLT version created, it may be used
in another Course only.
