Bits of BI – June 29

nickyvv.com---bits-of-bi_thumb1_thumIn accordance with Thomas LaRock I decided to also start my round-up of news from around the block of SQL Server, Technology or anything vaguely related to BI. And I might include some other things as well if I feel like it.
My plan is to do a weekly round-up, let’s see how that works out.
My latest post was 2 weeks ago, but here’s a new one! As we’re starting to go into summer and holidays, I might skip one edition in August also.

But for now, here’s the next edition of Bits of BI!


That concludes this edition of Bits of BI, feel free to share it with others!

My Data & BI Summit Recap

I finally came around to writing a wrap-up for the Data & BI Summit in Dublin last month.
No fancy pictures or colors, just a to-the-point summary.

New features

  • Incremental refresh – Premium (included in May update as preview feature)
  • Drillthrough with current filters and parameters (included in May update)
  • Common Data Service For Analytics (preview live)
  • Theme file additions coming soon:
    • Theme export
    • Background added to themes
    • Table/matrix headers
  • Persistent filters (per user) in the service
  • Buttons to trigger action (included in May update)
  • Q&A and linguistics
  • App workspaces without Office365 group

Modelling

  • Optimize your model (size)
  • Make use of Query folding in Power Query
    • Applies to Import mode only
    • Filter first, Transform later
    • Use supported transformations first, non-folding steps at the end
    • Writing a SQL query in Get Data prevents folding
  • Create a blank query with #shared to show a document library of all M functions (Blog)

Visualization

Governance

  • Use App Workspaces for DTAP
    • DEV_Finance
    • UAT_Finance
    • Finance
  • Use Onedrive for Business for versioning your pbix-files, with the same folders as the App Workspace
  • Use the API’s with PowerShell to copy resources between workspaces
    • Chriss Webb (@cwebb_bi) wrote a successful script in response to a video from Adam Saxton (@GuyInACube)

Best practices and notes

Visualization | Model

  • Driving table for measures
  • Hide unused columns
  • Totals in matrix and tables insensitive to row filters
  • Uniform naming of measures and calculations
  • Sync slicers
  • Add descriptions where possible
  • Make sure filters are not hardcoded

Governance

  • Add an about page with last refresh date time and description of Model
  • Version the Model
  • Schedule datasets using Admin account for one place to monitor failure notification emails
  • Use one drive as source control
  • Golden dataset
