1.11 data dictionary
This page is an (incomplete) documentation of the data structure in Chamilo 1.11.
- All fields called
c_idalways point to thecourse.idfield. - All fields called
user_idalways point to theuser.idfield. - All fields called
session_idalways point to thesession.idfield. - When fields called
group_idappear in a table with ac_prefix, they are usually referring to a course group (c_group_info.iid)
Note 1: All tables starting with a c_ are course-specific tables. They always include a reference to the course as the c_id field, and generally still hold a double identifier: iid is the new, platform-unique identifier, while the combination of id+c_id is the "old" unique identifier. Queries should use the iid field, although some have been left using id+c_id by lack of time during the transition.
Note 2: Sessions are really special, and most course resources tables include a session ID which can be either 0 or NULL (depending on the age of the table), or has a non-zero value. In case it has a (numeric) value, it means the resource is available inside the session-course and not inside the base course. If it is 0 or NULL, it means it is available inside the base course and for some resources, this means it is also visible in the session-course.
