選択肢
- A standard data extension, which receives its rows from a mapped import activity that reads a delimited file at the file location it watches.
- A random data extension, which selects a requested number of rows from a chosen source data extension through a sampling rule.
- A shared data extension, which publishes its rows from the enterprise level to the child business units of the account.
- A filtered data extension, which continually derives its rows from a chosen source data extension through a saved filter definition.
