Informatica Tutorial

In the Informatica tutorial we are going to learn the fundamentals or the basic concepts related to Informatica and also get a better understanding of how the Informatica ETL tool works. Informatica is a versatile tool that is commonly used for Extract, Transform, Load operations. However, we are also going to learn about Informatica basics, its architecture, Informatica transformations, Informatica PowerCenter, Informatica ETL, and many more concepts in depth.

What is Informatica?

Informatica has been a pioneer in data integration technologies over the years, however, it does allow us to wonder as to why there's so much hype about Informatica but most specifically, what's Informatica!

Informatica is an organization that provides energetic products for data integration. In the Informatica, i.e. Informatica PowerCenter products are most commonly used only for performing ETL operations, such as data quality, data masking, data replication, data virtualization, and master data management services. Informatica is working on a service-oriented architecture. It is capable of promoting services and resources on various computers. Informatica provides transformation capabilities that include filtering, aggregation, joining, and other functions.

The following are the Informatica key metrics that made it as the power in the data integration technology such as 7-year Annual CAGR:30%, partners: 450+, customers in more than 10+ countries, and #1 customer loyalty platform.

Why should you learn informatica?

Informatica is commonly utilized worldwide in organizations that want to remain on top of their results. With more than 30% of the world's information already stored in existing systems like Mainframe, there is a tremendous opportunity for a useful tool like Informatica when it comes to data integration. Along with that, Informatica is your key to the world of big data. There are therefore organizations that give top-notch wages to professionals who are well-versed in this top ETL tool.

Why is informatics so widely accepted by organizations?

Informatica is well known as the ETL tool and is opted by many organizations around the world in performing certain operations on the data systems in the backend. These operations include cleaning, modifying, the data based on some rules and regulations. And most notably it is known as the data integration tool.

Informatica is widely accepted due to the following reasons:

  • Informatica allows you to work collaboratively smoothly with information business and technology. 
  • It is remarkably simple to use and there are a lot of automated processes available. 
  • You can implement Informatica for the supervision of operations and governance 
  • Your data analysis and software can be fed with data in real-time 
  • Advanced data transformations can be done while moving from source to destination 
  • It also provides master data management to connect important data to a common destination.

Why is data integration technology used?

Nowadays every company processes a huge data set. They come from a variety of sources and need to be processed in order to provide insightful information on how to make business decisions. However, quite often, such data have the following challenges:

  • For the large organizations there will be bulk amounts of data. Here the data can be any format, thereby making available in different databases and in unstructured formats.
  • This unstructured data in multiple databases needed to be combined, collated, and news to work seamlessly.
  • Between the database, organizations implement the unique interfaces for the databases, any change in the particular database, then the interfaces needs to be updated.

Here the data integration technology came into existence to solve all those complicated challenges that arise in the organizations. With the help of this technology, data from different databases can be communicated very smoothly and reliably. However, data integration technology comes with differentarhcitecyure to perform the operations on the data. Informatica uses ETL architecture to perform data integration.

So we need to now learn what ETL is and how Informatica performs ETL to solve the business problems.

What is ETL?

ETL is a type of data integration that incorporates an architecture that extracts, transforms, and then loads data into a target database or file. It's the cornerstone of a data warehouse.

The ETL system helps in performing the following actions. They are:

  • Retrieve data from different sources 
  • Transforms and cleans the data 
  • Indexes of data 
  • Summary of data 
  • Loads data to the warehouse 
  • Tracks changes to the source data required for the warehouse 
  • Keys to Restructure 
  • Keeps the metadata in place 
  • Refresh the warehouse with updated data

ETL - 4You have learned what ETL is and what the ETL mechanism is, we are now in a better position to understand why Informatica is the best approach in such situations. We can also explain what the usual real-life situation is where Informatica will come in handy.

What is the use of Informatica ETL tools?

Informatica PowerCenter is a premium data integration solution currently available. The explanation it offers the best option for large companies is that it is: 

  • Database neutral and can therefore interact with any database 
  • The most effective data transformation tool. Converts data from one program to another format

Now we will learn about how informatica performs ETL.

How Informatica performs ETL?

ETL: Extract

  • PowerCenter can read data, row by row, from a table (or a group of similar tables) in a database, or from a file 
  • This database or file shall be referred to as the source 
  • The source structure is found in the source description entity.

Extract

ETL: Transform

  • Informatica PowerCenter converts rows to the format that the second (target) method would be able to use. 
  • The logic of this conversion is described in transformation objects.

Transform

ETL: Load

  • Informatica PowerCenter writes data, row by row, to a table (or group of associated tables) in a database, or to a file 
  • This database or file shall be referred to as the goal 
  • The configuration of the target is included in the target description object.

Load
Now we will learn about the real-time applications of the information.

Applications of informatica:

The real-time applications of Informatica are:

  • Changing from a legacy system like a mainframe to a modern database system requires data to be transferred from the old system to the new system. 
  • If a company wishes to set up its own data warehouse, an ETL tool will be required to transfer the data from output to the new data warehouse. 
  • Informatica can also be used as a data cleaning tool. 
  • Informatica also provides incorporation of online resources, business data, etc.

Now you have gained the basic concepts of Informatica and ETL.

We will now be going to learn about the Informatica architecture in depth.

Let's dig deeply now and grasp Informatica's Informatica Tutorial blog, its design and use case.

Informatica PowerCenter is the flagship product of Informatica and is often used interchangeably. Just to summarise, Informatica Powercenter is a single centralised enterprise data integration platform that enables businesses and government agencies of all sizes to access, discover and integrate data from virtually any business system, in any format, and distribute data across the enterprise at any speed. It is an ETL (Extract, Transform and Load) method with its key benefit over other ETLs.

  • It is stable and can be used in Windows and UNIX-based systems. 
  • It is high-performance and very easy to build, maintain and manage.
