Data Domain Discovery Options in Informatica Developer

You can select the source columns, data domains, and inference options when you create a profile to perform data domain discovery. You can also choose to omit columns from data domain discovery based on their datatypes and data length.

Data Domain Selection in Informatica Developer

The Data Domain Selection options list all the domains from the data domain glossary. You can search for specific data domains and select them before you run them as a part of data domain discovery.

Option	Description
Enabled as part of the "Run Profile" action	Includes the data domain discovery options when you run the profile.
Name	Data domain name.
Description	Description for the data domain.
Data Domain Group	Name of the data domain groups to which the data domain belongs.
Show data domain group in hierarchy	Lists all data domain groups with the data domains grouped under each data domain group.

Data Domain Column Selection in Informatica Developer

Option	Description
Column	Column name.
Datatype	Datatype of the column.
Precision	Maximum precision for the column.
Scale	Scale of the column.
Nullable	Indicates a column that can have null values.
Description	Description for the column.

Data Domain Inference Options in Informatica Developer

The inference options determine whether domain discovery must run on column data, column name, or both. You can also specify whether the profile needs to process all rows in the data source and set a minimum conformance percentage.

Option	Description
Override the default inference options	Enables you to change the predefined inference options.
Data	Profile runs on column data.
Column name	Profile runs on column titles.
Data and Column name	Profile runs on both column data and column titles.
All rows	Profile runs on all rows of the data source.
Maximum rows to profile	The maximum number of rows the profile can run on. The Developer tool chooses the rows starting from the first row in the source.
Minimum conformance percentage	The minimum conformance percentage of the column data to be eligible for data domain match. The conformance percentage is the ratio of number of matching rows divided by the total number of rows. Note: The Developer tool considers null values as non-matching rows. Columns containing a high number of null values may not result in data domain inference unless you specify a low value for minimum conformance percentage.
