After the testing phase is complete, the systems are now ready for implementation
List of Tasks for Data Warehouse Implementation and Deployment
Version the DW implementation scripts and environments & Freeze
- All scripts related to Extraction, Transformation and Loading
- All configurations of staging and Loading, and access environments
- All Data in the source systems.
Run the DW productionization processing
- Run the historical snap-shots (Some times they are done before hand to save time on the implementation weekend).
- Run the ETL scripts
- Run the refresh scripts for downstream data marts, systems.
Data Quality and DW implementation Verification
Business analysis teams mainly do this before they hand it over to users for their verification:
Data Warehouse End User Applications
End user applications need not be implemented along with the Data Warehouse. Typically Data Warehouse is implemented along with an OLAP tool and some end-user tools.
Same rigor is followed for end user applications as that of Data Warehouse, in terms of versioning, production processing and verification. Clients of the end user applications are installed and tested. End User Training - The end user training material is ready.
- A group of power users has already been taken through it (they themselves might be involved in creation of the training material). These power users will act as the trainers for their respective functions.
- The training material is divided into different category of users- Power users/Designers, Ad-hoc users (typically they place the ad-hoc queries and use the reports generated by the designers) and recipient users. (The users who only view the reports created by designers)
End User Support mechanisms and communication - 'Support mechanism for users' is established and communicated (Help line numbers, with in department mentors/trainers, escalation matrix)
- Support mechanism for technology staff (vendor help lines and escalation matrix.)
- The reporting and communication framework on defects, and user feedback is established.
