Question: What is connected transformation?

What is connected and unconnected transformation?

Connected transformation is connected to other transformations or directly to target table in the mapping. An unconnected transformation is not connected to other transformations in the mapping. It is called within another transformation, and returns a value to that transformation.

What are the different types of transformations in Informatica?

List of Transformations in Informatica

  • Source Qualifier Transformation.
  • Aggregator Transformation.
  • Router Transformation.
  • Joiner transformation.
  • Rank Transformation.
  • Sequence Generator Transformation.
  • Transaction Control Transformation.
  • Lookup and Re-usable transformation.

What is active and passive transformation in ETL?

A transformation can be active or passive. An active transformation can change the number of rows that pass through the transformation. … A passive transformation does not change the number of rows that pass through the transformation.

What is Joiner transformation?

Joiner transformation is an active and connected transformation. It provides the option of creating joins in the Informatica. By using the joiner transformation, the created joins are similar to the joins in databases. The joiner transformation is used to join two heterogeneous sources.

What is the difference between router and filter transformation?

Router transformation provides us the facility to capture the rows of data that do not meet any of the conditions to a default output group. A Filter transformation tests data for one condition and drops the rows of data that do not meet the condition. … Filter is single input and single output group transformation.

Why Union is active transformation in Informatica?

The Union transformation is an active transformation that you use to merge data from multiple pipelines into a single pipeline. … The Union transformation enables you to make the metadata of the streams alike so that you can combine the data sources in a single target.

Is update strategy an active transformation?

The Update Strategy Transformation in Informatica is an Active and Connected transformation. It is useful to update, insert, or delete the records in a target based on source table data. And the beauty of this transformation is: you can restrict the records from not reaching into the target table.

Is router active or passive transformation?

The Router transformation is an active transformation that you can use to apply a condition to incoming data. passes the row multiple times. You can either drop rows that do not meet any of the conditions or route those rows to a default output group.

Is sequence generator active?

Sequence generator is a passive and connected transformation, and it generates numeric sequence values such as 1, 2, 3, and so on. It does not affect the number of input rows. The Sequence Generator transformation is used to create unique primary key values and replace missing primary keys.

How can we connect two active transformations in Informatica?

Option 1: Load the content into a landing table or a temp relational table and use the Source Qualifier transformation. Option 2: Use the Joiner transformation if there is a common connecting key. This might impact the overall run time of the workflow based on the logic implemented and the volumes of data.
