  • 1. A Parents Guide to Raising Your Data Warehouse Rob Armstrong Teradata, Director of Data Warehouse Support (and Kyle and Amy’s Dad)
  • 2. With special thanks to…
  • 3. All data warehouses are different
  • 4. Have flexible guidelines Best practices work because the companies make them work – What works for one may not work for you Practices have to also fit into your financing and organizational philosophies – Is it your goal or your practice that is wrong? Take what works and build on it – Motivation, organization, funding
  • 5. Believe! Have a plan and commit to it.
  • 6. Can’t run to second while you are still standing on first Have a set of guiding principles – General processes that set the path – May be fine tuned within parameters Align and direct resources – ETL, Modeling, and Applications should all consider the total picture Put funding where it matters – What project funds integration? – What project funds data quality?
  • 7. Play date or Play mate?
  • 8. Need to have cooperation and integration Consolidated data – Still inconsistent and unrelated – Each group has little interest in other groups Integrated data – Consistent, relationships remain intact, reusable – Shared service levels and prioritization Shared outlook creates Friendship – Are your metrics shared across IT and Business – Do your business users take ownership of the data in the warehouse?
  • 9. It is almost always easier to quit… but rarely is it right thing to do
  • 10. Every obstacle is an opportunity Performance Challenges? – Value of action – Service level agreements Data Modeling? – Business definition consistency – Determining Ownership Funding – Business case development – Prioritization of development
  • 11. Unintended does not mean unexpected
  • 12. Mom always said “don’t play ball in the house” Understanding the consequences are critical Plan for the known, even if not immediate – “Baby-proof” your data warehouse – Look for where time and cost accumulate Growth always happens, are you ready? – Capacity, performance, expectations
  • 13. Have rules and enforce them, Sometimes you have to say NO
  • 14. You get the behavior that you tolerate Workload Management – Implies workload – Implies management System Migrations – What is missing? – Why is the old system still used. Where is the right place for work – Extracts are a red flag – ETL vs. ELT, Analytics heavy lifting
  • 15. A failure to learn is a failure to teach
  • 16. ElHi and beyond Fundamentals – Teradata works differently – Define and forget Relevance – Is your training being enforced with efforts – Lunch and learns, workshops, and others Breadth – Need business education as well – Understanding the data
  • 17. Expect better and you will get better
  • 18. Metrics, Measure, Modify Metrics – Do your metrics reflect your priorities? – Do your metrics align across functions? Measure – Are your metrics visible by all? – Do the measurements reflect timeliness Modify – What behavior do you want to see? – What rewards and communications are in use?
  • 19. If you want responsibility, you also must have accountability
  • 20. Ownership changes everything Data Definitions and quality – Not just consistent but also accurate – If it is wrong, what happens to your actions Value of performance – When do you know, when can you know? – What actions change with time? Where to put your next dollar – What data enhances your decisions? – How can you get others to join in?
  • 21. Have a plan for when they grow up
  • 22. What do you want to be? Data Warehouse Roadmap – What comes next – What can be leveraged elsewhere? Application, Data, and Systems – Plan is not just about data – What goal are you trying to reach? Priorities lead decisions, and actions – Governance, not regulation – How to get self service
  • 23. Realize that you have to let go… but you never stop being a parent
