Just passed AZ-900 certification!! I have written a page on all my tips and notes to help you get through as well, check it out here: https://powerbixpert.com/azure-az-900-microsoft-azure-fundamentals/ Notice that not all topics are covered there. What I suggest, and the best way I see to take advantage of these notes, is: Have fun, good luck!

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.” TheContinuar lendo “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 unconnectedContinuar lendo “Informatica Powercenter – Stored Procedure Transformation”

Informatica Powercenter – SQL Overrides

I did not really find any super good resource on this topic, but the overall idea of SQL override is to override a transformation default behavior by writing a SQL query instead. Of course, SQL overrides works only on relational data. There is no SQL Overrides for flat file. For instance, take a source qualifierContinuar lendo “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 youContinuar lendo “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 toContinuar lendo “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 whatContinuar lendo “Informatica Powercenter – Update Strategy Transformation SCD1 SCD2”

Informatica Powercenter – Union Transformation

If you are familiar to SQL you already know what UNION does. In fact, you might be wondering, is Powercenter Union the same as SQL union or SQL union all? It is UNION ALL. Here’s the official documentation on Powercenter Union transformation: The Union transformation is a multiple input group transformation that you use toContinuar lendo “Informatica Powercenter – Union Transformation”

Informatica Powercenter – Joiner Transformation

Here’s what the official documentation says about the Joiner Transformation: Use the Joiner transformation to join source data from two related heterogeneous sources residing in different locations or file systems. You can also join data from the same source. The Joiner transformation joins sources with at least one matching column. The Joiner transformation uses aContinuar lendo “Informatica Powercenter – Joiner Transformation”

Informatica Powercenter – Transformation Overview

I’m getting used to search and find relevant information within Informatica Powercenter official documentation website, and one of the good resources I like to use it, go to a transformation page and download the PDF guide. The downloaded file will contain all about transformation you need to know. For instance, if you go to JoinerContinuar lendo “Informatica Powercenter – Transformation Overview”

Informatica Powercenter – Filter Transformation

Let see what the official documentation says about Filter Transformation: “Use the Filter transformation to filter out rows in a mapping. As an active transformation, the Filter transformation may change the number of rows passed through it. The Filter transformation allows rows that meet the specified filter condition to pass through. It drops rows thatContinuar lendo “Informatica Powercenter – Filter Transformation”

Informatica Powercenter – Lookup Transformation

What is lookup? Whoever is familiar with Excel’s VLOOKUP might understand what this is about, but, anyway, let’s check what the official documentation says about it: https://docs.informatica.com/data-integration/powercenter/10-4-0/transformation-guide/lookup-transformation/lookup-transformation-overview.html“ “Use a Lookup transformation in a mapping to look up data in a flat file, relational table, view, or synonym. You can import a lookup definition from anyContinuar lendo “Informatica Powercenter – Lookup Transformation”
