- There is a scheduled process to get the day to day data from the source system to the Unix stage server
- From Unix stage to tera data stage actual operations are performed by using BTEQ, FL, ML Information, Data stage
- Once the staging database is ready now there is a load from stage 2 actual destination.
- During this load, if there any exception there moving into the error database
- Once the target database is ready the reporting people there generate cubes and creating various Reports from inuring.
