Data model

## Events, Series and Organisational Units

These are the names of the models in the back-end. They contain the information to list and categorise events in the application.

### Events

An event is a singular unit that contains information about an event. It contains:

• some basic information such as a displayName, description, notes, ...
• when the event takes place (start and end dates)
• where it takes place (location)
• by whom it's organised (organisers)

Series

A series lists events that logically belong together. In the case of a timetable application, this could be a workshop that's held every Tuesday at 10 in the first term. It has basic information such as a displayName and a description but most importantly groups the correct events

### Organisational units

These are used to provide (hierarchical) structure to the series and events. Each organisational unit can contain multiple series and/or events.

For example, the timetable application has identified the following types of organisational units:

• course
• subject (optional)
• part
• module

These organisational units all nest into each other. Meaning that a course can have multiple subjects, a subject can have multiple parts and a part can have multiple modules.

For example, a course with a subject could be modelled as such:

• Asian and Middle Eastern Studies (course)
  • Chinese Studies (subject)
    • Part IA (part)
      • C.4 Modern Chinese Translation and writing (module)
        • Chinese writing (series)
          • Thursday Oct 22 (event)
          • Thursday Oct 29 (event)
        • Chinese translation (series)
          • Thursday Oct 20 (event)
          • Thursday Oct 27 (event)

Most courses don't need subjects however and can be modelled like so:

• Archaeology (course)
  • MPhil (part)
    • GO1. Research Skills (module)
      • Field trip skills (series)
        • Wednesday Nov 2 (event)
        • Thursday Nov 3 (event)
      • Seminar skills (series)
        • Friday Nov 11 (event)
        • Wednesday Nov 16 (event)
