In the Column List:
- P = Primary key
- M = Mandatory field
- F = Foreign key (where the term is used loosely to indicate a surrogate key reference to a field in another table, not a formal constraint)
- DV = Default value
- In the Data Type column, varchar/nvarchar means that the data type is varchar except in multi-language databases that use Unicode, in which case the data type is nvarchar. (The Info Mart database in Cloud deployments is not multi-language.)
This dimension table enables Session Detail Record (SDR) facts to be described based on the activities encountered during the application session. Each row describes one activity (for example, booking an airline ticket).
The primary key of this table.
The surrogate key that is used to join to the CTL_AUDIT_LOG control table. The key specifies the lineage for data creation. This value can be useful for aggregation, enterprise application integration (EAI), and ETL tools — that is, applications that need to identify newly added data.
The name of the activity as defined in the Designer application.
|X||Ensures that the combinations of values that are stored in the dimension table are unique.|
