PowerCenter of Informatica: ETL Tools

Posted by sharmidevi on May 23rd, 2018

Informatica relies on ETL concepts abbreviated as Extract-Transform-Load. The overview of PowerCenter of Informatica: ETL Tools is explained in the below article. Informatica Training in Chennai at FITA will make you familiar from scratch.

Define ETL?

ETL is a data warehousing abstract of data extraction where data from numerous various databases.

ETL Invention

The international software company is based on Lexington Ab Initio; United States framed by a GUI based processing software known as ETL. Other which is related to this historic transformation journey is explained below.

Applying Informatica-ETL concepts for Real-Time Business

The company Informatica offers data integration products like master data management, data Quality, ETL, data virtualization, data masking, data replica and much more. Learn about this in Informatica Training Center Chennai. The most commonly used Data integration tool for fetching and connecting data from the various source is Informatica ETL.

Here are a few types of approaching this software:

  • To set up Data Warehousing in a company, the data is moved to Warehouse from Production/data gathering
  • A company moving from existing software to a new database system
  • It performs as a data cleansing tool where data is identified, checked and remove corrupt or inaccurate documentation from a database.

Informatica - ETL tool implementation

Transform:

A set of logical and rules functions like scrub of data are applied in the data to prepare for loading into a data source target. Data cleaning implies bypassing the proper data into target source. There is various kind of transformation in applied data as per the requirements of a business. All these are taught in detail in Informatica Training Institute in Chennai. A few maybe row or column based, calculated and coded values, joining various sources, key-based etc.

Extract:

The most common data-source formats include relational data, flat and XML files, data structures or Information Management System. It is performed to confirm the data pulled from the sources which have the accurate values in a domain.

Load:

In this, the data is loaded into the target source. The three phases are executed parallel to the other to start or begin.

Other features of ETL Tool

Data Reuse, Data Recovery and Data Re-Run

Each data row is delivered with row_id and every piece of the process is provided with run-id which can run one track by these ids’. There are also checkpoints generated to certain phases of the process as finished. These need to re-run the query for task completed.

Parallel Processing:

Parallel Processing concept is used for implementing ETL. It computes executing on multiple processes simultaneously. It works on three types of parallelism.

  • Some components are executable which runs simultaneously on various data for the same job
  • Pipeline permits many components to rush concurrently on same data
  • Data splitting into a small file by a single file
