Biml for Beginners: Speed up your SSIS development (SQLSaturday Tallinn)

  1. 1. Biml for Beginners: Speed Up Your SSIS Development Cathrine Wilhelmsen SQLSaturday Tallinn · November 18th 2017
  2. 2. 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!

  7. 7. job done! new standards ...yay Ever experienced this?
  8. 8. It's time for a change!
  9. 9. 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 Cubes
  10. 10. Why use Biml? SSIS: Plumbing Biml: Business Logic
  11. 11. SSIS: Plumbing Time wasted 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 High risk of manual errors More packages, more time
  12. 12. 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 reuse and scale
  13. 13. Will Biml solve all your challenges? Probably not... Biml is a tool for generating SSIS packages Biml is not a pre-defined ETL framework Biml is not a tool for automated deployment ...but it will solve many challenges!
  14. 14. How can Biml help you? Biml is great for large projects with common patterns… Timesaving: Many SSIS packages from one Biml file Reusable: Write once and run on any platform Flexible: Start simple, expand as you learn …but is also useful for smaller projects!
