Working with the relationships graph
When you create, change, and view the relationships in a FileMaker Pro database, you use the relationships graph.
Each box on the relationships graph represents a table occurrence, a separate view into a single underlying source table. A single source table may appear as many table occurrences, each with a different name and each of which you can relate to other table occurrences.
You create a relationship between two table occurrences at a time. You can create chains of relationships between many table occurrences. However, FileMaker Pro prevents you from creating a chain of relationships that relates a table occurrence back to itself, which can’t be resolved.
Because each relationship represents an additional set of criteria, you must be aware of the context within the relationships graph. Context is the point in the relationships graph from which a relationship is evaluated. Because the graph is never a cycle, each point along the graph offers a different perspective into your data.
To display the relationships graph:
1. Choose File menu > Manage > Database.
2. Click the Relationships tab, and use the buttons and other elements in the relationships graph to define relationships.
