What are the different types of transformations in Informatica?

What are the different types of transformations in Informatica?

There are 3 Informatica transformations viz. External Procedure, Lookup, and Stored Procedure which can be unconnected in a valid mapping (A mapping which the Integration Service can execute).

How many types of transformations are available?

1. Here are two types of transformations based on the change in several rows, such as: Active Transformations. Passive Transformations.

What are the active and passive transformations in Informatica?

Active Transformations are those who modifies the data rows and the number of input rows passed to them. Passive transformations are those who does not change the number of input rows. In passive transformations the number of input and output rows remain the same, only data is modified at row level.

What all are passive transformation in Informatica?

The following are the list of passive transformations used for processing data:

  • Expression Transformation in Informatica.
  • Sequence generator transformation in Informatica.
  • Stored procedure transformation in Informatica.
  • Lookup Transformation in Informatica.
  • XML source qualifier transformation in Informatica.

How many types of transformations are there in ETL?

Architecturally speaking, there are two ways to approach ETL transformation: Multistage data transformation – This is the classic extract, transform, load process. Extracted data is moved to a staging area where transformations occur prior to loading the data into the warehouse.

What types of transformation ports are supported?

Table of Contents

  • Active Transformations.
  • Passive Transformations.
  • Unconnected Transformations.
  • Multi-Strategy Transformations.
  • Transformation Descriptions.

What is union 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 merges data from multiple sources similar to the UNION ALL SQL statement. …

What is active and inactive transformations?

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 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 are the three most common transformations in ETL processes?

Let’s dive in and learn how to convert raw data into insights through the three-step ETL process.

  • 1st Step – Extraction.
  • 2nd Step – Transformation.
  • 3rd Step – Loading.

Which transformation support variable port in Informatica?

An expression transformation in Informatica supports writing expression either in variable ports or only in output ports.

In Informatica, active transformations modify rows and number of input rows while passive ones do not change several input rows and no new rows are created or existing dropped. Following are the types of active transformations: 1. Source Qualifier Transformation This transformation is active and connected.

What is transtransformation In Informatica?

Transformation allows you to define business rules for processing data. Informatica PowerCenter Designer provides a set of transformations to perform specific functions. Informatica Transformations are classified in to Active Transformations and Passive Transformations.

What are the different types of transformations in SQL Server?

Here are two types of transformations based on the change in several rows, such as: Active Transformations are those who modify the data rows, and the number of input rows passed to them. For example, if a transformation receives 10 numbers of rows as input, and it returns 15 numbers of rows as an output, then it is an active transformation.

What are connected transformations in Informatica?

In Informatica, during mappings the transformations which are connected to other transformations are called connected transformations. For example, Source qualifier transformation of Source table EMP is connected to filter transformation to filter employees of a dept.
