Biml for Beginners: Script and Automate SSIS development (Hybrid VC)

  1. 1. Biml for Beginners: Script and Automate SSIS Development Cathrine Wilhelmsen PASS Hybrid VC · July 30th 2018
  2. 2. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Session Description Are you tired of creating and updating the same SSIS packages again and again? Is your wrist hurting from all that clicking, dragging, dropping, connecting and aligning? Do you want to take the next step and really speed up your SSIS development? Say goodbye to repetitive work and hello to Biml, the markup language for Business Intelligence projects. In this session we will look at the basics of Biml. First learn how to use Biml to generate SSIS packages from database metadata. Then see how you can reuse code to implement changes in multiple SSIS packages and projects with just a few clicks. Finally, we will create an example project that you can download and start with to speed up your SSIS development from day one. Stop wasting your valuable time on doing the same things over and over and over again, and see how you can complete in a day what once took more than a week!

  6. 6. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Once upon a time…
  7. 7. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Meet Sandra, the SSIS developer
  8. 8. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Sandra has to create a new staging project with 100+ SSIS packages
  9. 9. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Sandra gets quite bored of creating the same package over and over and over
  10. 10. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Yay, Sandra has finally completed her project!
  11. 11. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) But Sandra's manager has just a few new requirements…
  12. 12. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Sandra gets to update every single SSIS package one… more… time…
  13. 13. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) …yay
  14. 14. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) It's time for a change!
  15. 15. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net)
  16. 16. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) What is Biml? Business Intelligence Markup Language Easy to read and write XML language Describes business intelligence objects: • Databases, Schemas, Tables, Views, Columns • SSIS Packages • SSAS and Azure Data Factory *
  17. 17. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Why use Biml? SSIS: Plumbing Biml: Business Logic
  18. 18. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) SSIS: Plumbing Spend time on dragging, dropping, connecting, aligning Create the same package over and over again with minor changes Standards, patterns and templates must be defined up-front Changes must be done in every single package Higher risk of manual errors More packages, more time
  19. 19. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Biml: Business Logic Spend time on what is unique in a package Create a pattern once and reuse for all similar packages Handle scope and requirement changes quickly and easily Changes can be applied to all packages at once Lower risk of manual errors Longer time to start, but then automate and reuse
  20. 20. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Will Biml solve all your challenges? Biml is a tool for generating SSIS packages Biml is not a pre-defined Data Warehouse framework Biml is not a tool for automating deployment
  21. 21. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) How can Biml help you? Timesaving: Many SSIS packages from one Biml file Reusable: Write once and run on any platform Flexible: Start simple, expand as you learn
  22. 22. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) What if you don't have 100+ packages? Source Control: Keep track of actual logic changes Simplify: Untangle complex packages for quick edits SQL Scripts: Use Biml instead of dynamic T-SQL

  69. 69. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Annotations Store custom metadata by attaching tags to Biml objects: <Annotation Tag="TagName">Custom Value</Annotation> Higher tier files can get tags from lower tier files
  70. 70. © 2018 Cathrine Wilhelmsen (hi@cathrinew.net) Annotations Create annotations: <OleDbConnection Name="Dest"> <Annotations> <Annotation Tag="Schema">stg</Annotation> </Annotations> </OleDbConnection> Use annotations: RootNode.OleDbConnections["Dest"].GetTag("Schema");
