Case Tables
There are a number possibilities for the case table of a build activity:
- The base table or view contains all the data to be mined.
- Other tables or views contain additional simple attributes of an individual, such as first name, last name, or contact information.
- Other tables or views contain complex attributes of an individual (sometimes called "transactional" data), such as a list of products purchased or a list of telephone calls for a given period.
- The data to be mined consists of transactional data only; in this case, the base table must be constructed from the transactional data.
In the first case, do not check Join additional data with case table. In the other three cases, check Join additional data with case table and join data from one or more tables to the case table.
For optimal performance of the wizard, the case table and any joined tables or views must be set up properly. See Setup for Tables for details.
