Transcript of "Dv in few clicks"

  1. 1. Data Vault (DV) Modeling in few clicks EDW Modeling 1
  2. 2. Goal: - Demonstrate feasability of EDW modeling with DV modeling approach in few steps using data modeling tools - Speed up time spend in EDW Audience: • Managers • Analysts Creating a Data Vault Model in few steps 2
  3. 3. Tool used in this example: - Sybase PowerDesigner 16.5 - Windows 8 - Approach used described on http://www.dwhautomation.org (created by Lulzim Bilali) and referenced by Pieter Rambags (NL) on Linkedin Data Vault (DV) Modeling in few clicks 3
  4. 4. • Step 1: • Take a classical ER diagram : Data Vault (DV) Modeling in few clicks 4
  5. 5. • Step 2: - Create an extension (in this case we created a « DV » extension); this extension must permit to identify « business keys », notions of Hubs and satellite (see DV theory). Data Vault (DV) Modeling in few clicks 5
  6. 6. • Step 3: - Locate Business Keys in source model (you can also use automatic data profiling to help your analyst in this step) Data Vault (DV) Modeling in few clicks 6
  7. 7. • Step 4: - If you create the extension from scratch, add contextual menu and script following model analysis algorithm as described (see slide 3); if you use our extension, do nothing  it’s done. Data Vault (DV) Modeling in few clicks 7
  8. 8. • Execute the algorithm, in our case just right click, choose « DV » then « Analyse ». Data Vault (DV) Modeling in few clicks 8
  9. 9. • Check results: • On source models, few colors are added and new extended attributes are positionned (« is Satellite », « Is Hub » …). Data Vault (DV) Modeling in few clicks 9
  10. 10. • During algorithm execution, a new data model is created in less than 1 second. Data Vault (DV) Modeling in few clicks - Satellite (Yellow) - Links (Red) - Hubs(Blue) 10
  11. 11. Advantages • Spend less time in building complex models • Results can be reused by other automated solutions • Integrated inside PowerDesigner Repository • Next steps: load automation… to be continued Data Vault (DV) Modeling in few clicks 11
