This section provides the database definitions in {productName}.

Here are a few points to note about the database descriptions:

* The documentation mentions some constraints, for example NOT NULL and UNIQUE KEY.<br />These constraints may not be enforced by all databases and may be difficult to enforce when using views. However, {productName} will assume that the data satisfies these constraints and may behave unpredictably if they are not satisfied.

* The documentation includes the joins used between the tables/views.<br />These are provided for informational purposes, though they may optionally be used to construct keys and indices to help maintain data integrity and improve performance.

Each cube in {productName} uses a star schema with many-to-one joins radiating out from a base table. The base tables are as follows:

| Cube                     | Base Table                           |
| ------------------------ | ------------------------------------ |
| StandardisedApproachCube | [SASENSITIVITIES](./sasensitivities) |

Additionally, there are "isolated" tables that are not part of the star schema but are still used in the cubes.
