About the relationships graph
When you work with tables in the relationships graph, you organize your view
of your data. Tables shown in the relationships graph can be located in the
current FileMaker
Pro file, in an external FileMaker Pro file, or in an external
ODBC data source.
Related table For relational databases, the table that contains the data you want to
access and work with in the current table.
For lookups, the table that contains the data to copy.
A table can be related to itself. This is called a self-join.
Relational
operators
In the relationships graph, the symbols that define the match criteria
between one or more pairs of fields in two tables. These include: equal
(=), not equal (≠), greater than (>), greater than or equal to (≥), less than
(<), less than or equal to (≤), and all rows, or cartesian product (X).
Relationship Relationships provide access to data from one table to another.
Relationships can join one record in one table to one record in another
table, one record to many other records, or all records in one table to all
records in another table, depending on the criteria you specify when you
create the relationship in the relationships graph. (A relationship is
sometimes called a link or a join expression.)
Relationships
graph
In the Relationships tab of the Manage Database dialog box, you can
see the occurrences of tables both in the current file and from any
external, related database files. In this relationships graph, you join
tables and change relationships between fields in different tables.
When you create a new table, a visual representation, or occurrence, of
the table appears in the relationships graph. You can specify multiple
occurrences (with unique names) of the same table in order to work
with complex relationships in the graph.
Source file The file from which you add a table to the relationships graph.
Source table The table upon which one or more tables in the relationships graph are
based. The source table is the table defined in the Tables tab of the
Manage Database dialog box.
