Assignment 1
A conceptual data model will contain the attributes propertyAddress, numberOfRooms, rateableValue, surnameOfOwner, initialsOfOwner. The data model structure should be capable of showing (a) who owns a given property, and (b) which property an owner occupies. An owner does not necessarily occupy a property which he or she owns. Suggest two entity types which might be recognised in an entity-relationship model, and suggest two possible relationship types between these two entities. Draw an entity-relationship type diagram. Your diagram may be hand drawn or through a tool.
