What are the different types of transformations in Informatica and explain them briefly?

Types of Transformations in Informatica

There are several types of transformations in Informatica that are used to manipulate data during extraction, transformation, and loading processes. Here are some of the key types of transformations:

1. Expression Transformation: Allows you to perform calculations and manipulate data using expressions and functions.
2. Aggregator Transformation: Used to perform aggregate calculations such as sum, average, count, etc. on groups of rows.
3. Lookup Transformation: Enables you to look up data from a relational table, view, or synonym based on a key.
4. Filter Transformation: Filters rows based on specified conditions.
5. Joiner Transformation: Joins data from multiple sources based on a common key.
6. Rank Transformation: Assigns ranks to rows based on specified criteria.
7. Router Transformation: Routes input data to multiple output groups based on specified conditions.
8. Sorter Transformation: Sorts data based on specified ports.
9. Sequence Generator Transformation: Generates primary key values or sequence numbers.

Each type of transformation serves a specific purpose in data integration and plays a crucial role in transforming data as needed for business requirements.
