Informatica developed a software tool to perform ETL operations on data, known as Power Center. We can develop three components under Power Center Tools to perform the ETL Process –

1. Mapping
2. Session
3. Workflow

Mapping :

1. It is used to define the flow of data from source to target.
2. Mapping is done with the help of transformation objects.
3. A mapping can consist of one or more session.

Session :

1. It is an object created for a specific mapping object.
2. It is used to specify the connectivity for different source, target, and other databases.
3. Every session should have only one mapping.
4. A session can consist of one or more workflows.

Workflow :

1. It is an object which is a collection of tasks.
2. All the ETL operations and Mapping is listed under workflow operations,
3. Every workflow can have more than one or more session.
   

Uses of Informatica :

• Informatica became popular because most often we have a large amount of Big Data, and we need to perform some backend operations on the data, where the operations can be like cleaning of the data, changing the attributes, modifying the null values, etc.  
• Informatica can be used to migrate the data warehouse form certain legacy system to the cloud environment.
• Informatica offers a huge set of instructions such as integration of various data sources which can be in any form of semi-structured, un-structured, or structured data. 
• Informatica helps in scheduling the data operations in the form of event-based triggers. 
• It also offers cloud-based services, which can help organizations to use it with a minimum amount of setup.
• Informatica also has the feature of metadata. As a result, the information about the process and data operations are also protected.
