Data mining activities require data that is defined within a single table or view. The information for each record must be stored in a separate row. The data records are commonly called cases. Each case can optionally be identified by a unique case ID. The table or view itself can be referred to as a case table.
The CUSTOMERS table in the SH schema is an example of a table that could be used for mining. All the information for each customer is contained in a single row. The case ID is the CUST_ID column. The rows listed in Example 3-1 are selected from SH.CUSTOMERS.
Note:
Oracle Data Mining requires single-record case data for all types of models except association models, which can be built on native transactional data. See "Using Market Basket Data".
