Tables and Relationships
Pyramid automatically assigns relationships between the tables. Table metadata can be edited, and tables duplicated or hidden.

By default, 'auto-relationships' are used to create joins via a heuristic model that matches primary key columns to foreign key columns. This model can be changed to match tables by table name or column name, or auto-relationships can be disabled.
Regardless of whether or not auto-relationships are enabled, and which heuristic model is selected, you can add new joins, and delete or edit existing ones.

Pyramid uses heuristics to determine things like column visibility, data type, measure formatting, and to organize columns into logical folder groupings. All of these things can be edited if required.
Columns can be edited from both the Tables panel and the Columns panel. Where you choose to edit columns depends largely on personal preference, but there are 2 main differences between the 2 panels:
- The Tables panel shows joins between the tables, while the Columns panel does not.
- The Tables panel presents a graphical representation of the tables and columns, while the Columns panel presents a tabular display.

Using heuristics, Pyramid determines which columns in the model are measures, and assigns them a format and folder. You can manually define columns as measures, and you can edit measures by changing the measure type, the folder, and format.
