Instructions

For the following 3 subjects, identify all of the related entities and attributes of those entities that you can think of:

  • Libraries
  • Art Collections
  • Comic Book Collections

You can express your lists of entities and attributes as simple lists in a textfile, just make sure that it's obvious what is an entity and what is an attribute. For example, a school might have:

  • students
    • first name
    • last name
    • phone number
  • teachers
    • first name
    • last name
    • office number
  • classrooms
    • room number
    • seats available
    • has computers?
  • buildings
    • address
    • description

In this list the left justifies items are entities and the indented items below them are their attributes.
