What is Informatica? Why do we need it?
Established in 1993 by Gaurav Dhillon and Diaz Nesamoney, Informatica is a software development company. Informatica is an ETL platform providing solutions for data integration. The devices used to collect, transform, and load the data are ETL devices. We may also conclude that Informatica is an ETL method, which is used to extract data from a database and save it in a separate database.
- Extract: Extract is a method used to extract data from a single database. An ETL tool extracts data from multiple sources in this step. To verify whether or not they suit the target value, verification laws are applicable. If the validation fails, the data will be declined.
- Transform: Transform is the method of transforming one type into the other in just such a way that data can also be stored in another database. Data formatting, resorting to row or column data, merging the two possible values into one, and separating the data into two or three values are transformed.
- Load: Data is transferred to the target database in the load phase. The ETL procedure is finished once the data is loaded.
