A Parent's Guide to Raising your Data Warehouse

  1. 1. A Parents Guide to Raising Your Data Warehouse Rob Armstrong Teradata, Director of Data Warehouse Support (and Kyle and Amy’s Dad)
  2. 2. With special thanks to…
  3. 3. All data warehouses are different
  4. 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. 5. Believe! Have a plan and commit to it.
  6. 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. 7. Play date or Play mate?
  8. 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. 9. It is almost always easier to quit… but rarely is it right thing to do
  10. 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. 11. Unintended does not mean unexpected
  12. 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. 13. Have rules and enforce them, Sometimes you have to say NO
  14. 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. 15. A failure to learn is a failure to teach
  16. 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. 17. Expect better and you will get better
  18. 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. 19. If you want responsibility, you also must have accountability
  20. 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. 21. Have a plan for when they grow up
  22. 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. 23. Realize that you have to let go… but you never stop being a parent
