Oracle Data Mining supports two formats for data tables:
Sequence Id
,
Attribute Name
, and Value
. This format is also called transactional format or multiple record case format.Multi-Record Case format is typically used for market basket data.
Not all algorithms support transactional data for input.
For Association models, require transactional format.
All other models require a non-transactional case table. Transactional data can be added by joining it to the case table.
All models except for Association models can have either pure single-record case format input or input consisting of transactional data joined to a non-transactional case table.
RESTRICTION: Attribute Name in Multi-Record Case format should be no longer than 30 characters. ODM does not support longer attribute names (that is, attribute names having data type VARCHAR2(n) with n>30) in operations such as model building.
