Is Router an active or passive transformation?

What is Router transformation?

Router transformation is an active and connected transformation which is similar to filter transformation, used to filter the source data. … So, router transformation gives multiple output groups, and each output group can have its own filter condition.

Is an example of passive transformation?

For example, the Filter transformation is active because it removes rows that do not meet the filter condition. A passive transformation does not change the number of rows that pass through the transformation.

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.

What groups are involved in Router transformation?

Output groups: Router transformation has two output groups. They are user-defined groups and default group. User-defined groups: Create a user-defined group to test a condition based on the incoming data. Each user-defined group consists of output ports and a group filter condition.

What are the types of groups in Router transformation?

Router Transformation can be created by 2 types of groups :

  • Input group : Input group receives the data from source pipeline and have only one i/p group.
  • Output group : User defined and default are the two types of O/P group.

Why Joiner transformation is active?

The Joiner transformation is an Active and Connected Informatica transformation used to join two heterogeneous sources. The joiner transformation joins sources based on a specified condition that matches one or more pairs of columns between the two sources.

Which transformations are active in Informatica?

The following are the list of active transformation in Informatica used for processing the data –

  • Source quilter transformation in Informatica.
  • Filter transformation in Informatica.
  • Ruler transformation in Informatica.
  • Rank Transformation in Informatica.
  • Sorter Transformation in Informatica.

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.

What is normalizer transformation in Informatica?

The Normalizer transformation is an active transformation that transforms one incoming row into multiple output rows. … When the Normalizer transformation returns multiple rows from an incoming row, it returns duplicate data for single-occurring incoming columns.

What is update strategy transformation active or passive?

Update strategy transformation is an active and connected transformation. Update strategy transformation is used to insert, update, and delete records in the target table. It can also reject the records without reaching the target table.

IT IS IMPORTANT:  Quick Answer: How do you show affine transformation?

Is lookup an active or passive transformation?

When you configure the Lookup transformation to return a single row, the Lookup transformation is a passive transformation. When you configure the Lookup transformation to return multiple rows, the Lookup transformation is an active transformation. You can use multiple Lookup transformations in a mapping.

What is the difference between source qualifier and filter transformation?

Source Qualifier reduces the number of rows used throughout the mapping and hence it provides better performance. The filter condition in the Source Qualifier transformation only uses standard SQL as it runs in the database. Filter transformation filters rows coming from any type of source system in the map-ping level.

What is sequence generator in Informatica?

The Sequence Generator transformation is a passive and connected transformation that generates numeric values. Use the Sequence Generator to create unique primary key values, replace missing primary keys, or cycle through a sequential range of numbers.
