ETL is extraction , transforming , loading process , you will extract data from the source and apply the business role on it then you will LOAD it in the TARGET
The steps are :
1-DEFINE the source (create the odbc and the connection to the source DB)
2-define the target (create the odbc and the connection to the target DB)
3-create the mapping ( you will apply the business role here by adding transformations , and define how the data flow will go from the source to the target )
4-create the SESSION (its a set of instruction that run the mapping )
5-create the work flow (instruction that run the session)
