Description

The De-normalizer step allows you de-normalize data by looking up key-value pairs. It also allows you to immediately convert data types.

Options

Option	Description
Step name	Name of the step; this name has to be unique in a single transformation.
Key field	The field that defined the key of the output row.
Group fields	Specify the fields that make up the grouping here.
Target fields	Select the fields to de-normalize by specifying the String value for the key field (see above). Options are provided to convert data types. Strings are most common as key-value pairs so you must often convert to Integer, Number or Date. If you get key-value pair collisions (key is not unique for the group specified) specify the aggregation method to use.

Metadata Injection Support

You can use the Metadata Injection supported fields with ETL Metadata Injection step to pass metadata to your transformation at runtime. The following Value fields of the Row Denormaliser step support metadata injection:

Target Filename, Value Fieldname, Key Value, Type, Format, Length, Precision, Currency, Decimal, Group, and Aggregation

Example

CustomerId	Key	Value
101	COUSINS_FIRST_NAME	Mary
101	COUSINS_SECOND_NAME	J.
101	COUSINS_LAST_NAME	Blige
101	COUSINS_BIRTH_DATE	1969/02/14
101	COUSINS_INCOME	1723.86
