Klassetiltabellmapping

Klassetiltabellmapping is a terminology used primarily in educational technology and management information systems to describe the linkage between class schedules (klassetid) and the database tables that hold scheduling information. The term combines the Swedish word “klassetid” (class time or class schedule) with the English concept of a table‑mapping, indicating a structured representation that associates time slots, rooms, instructors, and enrolled students within a database schema. Such a mapping is essential for systems that need to query, display, or modify course timetables, to ensure consistency across reporting, conflict detection, and resource allocation modules.

In practice, klassetiltabellmapping is employed by universities, high schools, and online learning platforms to model the many‑to‑many relationships between courses, instructors, and classrooms. Typical implementations involve a junction table—often called ClassScheduleMap—that stores foreign keys to Course, Instructor, Room, and TimeSlot tables. The map also includes fields for semester identifiers, credit units, and status flags (active, deleted). By normalizing the schedule information into a dedicated table, institutions avoid redundant data, simplify updates when a course changes time or location, and enable efficient queries for timetable generation or room booking analysis.

Implementation guidelines recommend using composite primary keys on the mapping table, enforcing referential integrity with appropriate foreign key constraints, and indexing the most frequently queried columns (e.g., InstructorID, TimeSlotID). Many open‑source learning management systems such as Moodle and Sakai expose similar schedule‑mapping tables within their database schemas, allowing administrators to extend or customize the structure. Open standards such as the Learning Information Services Architecture (LISA) reference schedule‑mapping concepts to promote interoperability between campus information systems.
