Session Cache
When running a session using a data store, the data is stored in the 1Validate session cache. When the session has finished, the cache is cleared.
When the data is read from a data store to create the cache, then by default the cache has the same structure (i.e. schema) as the source data.
Optionally, you may wish to modify the schema of the source data whilst it is held in the cache. This could be so that your source data can be used with existing rules that expect a certain schema, or to make rule writing easier. This can be achieved through schema mapping (see Schema Mapping).
