You need to show the following:
- A box for each table in the database, with all of the variables listed inside the box.
- A line connecting each relationship. It runs between the variables in the two tables that are related.
- Indications of whether the relationship is one-to-one, one-to-many, or many-to-many. These are usually a 1 for the "one" end of a line, and an infinity symbol for the "many" end of a line.
Microsoft Access uses ER diagrams in the Relationships window to let you use the mouse to create and remove relationships.
Google "ER diagram" to see more.
