Pupils will analyse social networking sites they use and identify the kinds of information that can be found on them. They will then group different pieces of information into collections (entities) and then think about how they are related to each other. They will then be able to create an ER diagram showing the relationships between them.

Pupils will be able to understand

  • what an entity and an attribute are
  • how these are related to instances and values
  • what a relationship is and the different types of relationships between different entities
  • the purpose of an ER diagram
  • that ER Diagrams are one way of creating an information model

Level: Higher Computing Science

Duration: 1 or 2 periods

Teaches: ER design notation, relational database structures and relationships
