Using Informatica Mapping Templates Overview

Using Informatica Mapping Templates Overview

Informatica mapping templates are predefined mapping templates that cover common data warehousing patterns, such as slowly changing dimensions and incremental load. These templates provide solution for the most common issues in the data warehousing designs. You can use the predefined mapping templates to document methods to map or process data.
Informatica provides predefined mappings for the following types of templates:
  • Type 1 Slowly Changing Dimensions
    . Loads a slowly changing dimensions table by inserting new dimensions and overwriting existing dimensions.
  • Type 2 Slowly Changing Dimensions.
    Loads a slowly changing dimensions table with new and changed dimensions. There are three types of type 2 slowly changing dimensions.
  • Type 3 Slowly Changing Dimensions
    . Loads a slowly changing dimensions table by inserting new dimensions and updating values in existing dimensions.
  • Remove Duplicates
    . Duplicate records are frequently found in source data. The Remove Duplicates Mapping template helps you remove duplicate data from source tables.
  • Incremental Load
    . You can use the Incremental Load template when you want to identify and capture the data that has been added, changed, or deleted in a database table.
