Informatica Powercenter – XML Transformation (XML Source Qualifier, XML Parser, XML Generator)
I highly recommend reading the first three links on References, at the end of this post. About XML What says the official documentation: “Each group in an XML source definition is analogous to a relational table, and the Designer treats each group within the XML Source Qualifier transformation as a separate source of data.” TheContinue reading “Informatica Powercenter – XML Transformation (XML Source Qualifier, XML Parser, XML Generator)”
Informatica Powercenter – Stored Procedure Transformation
Let’s start checking out what the official documentation has to say: “A Stored Procedure transformation is an important tool for populating and maintaining databases. Database administrators create stored procedures to automate tasks that are too complicated for standard SQL statements. The Stored Procedure transformation is a passive transformation. You can configure a connected or unconnectedContinue reading “Informatica Powercenter – Stored Procedure Transformation”
Informatica Powercenter – SQL Overrides

Informatica Powercenter – User Defined Functions
User Defined Function (UDF’s) is a way Powercenter gives us to create our own personal, reusable, functions. We can use our UDF’s in Expression Transformations in order to reuse expression logic. For instance, if you want to RTRIM() LTRIM() and UPPER() several ports, so, instead of writing all these 3 functions all the time youContinue reading “Informatica Powercenter – User Defined Functions”
Informatica Powercenter – Mapplets
Here what official documentation says about Mapplets: A mapplet is a reusable object that you create in the Mapplet Designer. It contains a set of transformations and lets you reuse the transformation logic in multiple mappings. When you use a mapplet in a mapping, you use an instance of the mapplet. Any change made toContinue reading “Informatica Powercenter – Mapplets”
Informatica Powercenter – Update Strategy Transformation SCD1 SCD2
Something worth keeping in mind: in order to Update Strategy to work properly you need to make sure that your target table has a primary key. Here’s what the official documentation says about Update Strategy Information: “The Update Strategy transformation is an active transformation. When you design a data warehouse, you need to decide whatContinue reading “Informatica Powercenter – Update Strategy Transformation SCD1 SCD2”
