What is ETL Testing?
ETL Testing stands for Extract Transformation and Load Testing, It collects the data from different sources from Heterogeneous System (DB), and Transform the data intobusiness required format and then loads into Data warehouse.
Redprism provide industries best training in ETL Testing (DWH Testing) includes following steps:
1. Understanding of data to be reported.
2. Understanding and review of data model.
3. Data Quality Assessment of Source data.
4. Schema testing (source and target).
5. Verification of transformation rules and many more.
The data in a Data Warehouse system is loaded with an ETL (Extract, Transform, and Load) tool. As the name suggests, it performs the following three operations
ü Extracts the data from your transactional system which can be an Oracle, Microsoft, or any other relational database.
ü Transforms the data by performing data cleansing operations, and then
ü Loads the data into the OLAP data Warehouse.
You can also extract data from flat files like spreadsheets and CSV files using an ETL tool and load it into an OLAP data warehouse for data analysis and reporting. Let us take an example to understand it better.
