Biml for Beginners: Speed Up Your SSIS Development (PASS Summit 2016)

  1. 1. Biml for Beginners Speed Up Your SSIS Development Cathrine Wilhelmsen, Data Warehouse Architect
  2. 2. 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!

  11. 11. Ready for a change?
  12. 12. Business Intelligence Markup Language Easy to read and write XML language Describes business intelligence objects: • Databases, Schemas, Tables, Views, Columns • SSIS Packages • SSAS Cubes What is Biml?
  13. 13. Why use Biml? SSIS: Plumbing Biml: Business Logic
  14. 14. Time wasted on dragging, dropping, connecting, aligning Create the same packages 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 SSIS: Plumbing
  15. 15. 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 Biml: Business Logic
  16. 16. Biml is a tool for developing SSIS packages Biml is not a tool for automated deployment Biml is not a pre-defined ETL framework Will Biml solve all your challenges?
  17. 17. Timesaving: Many SSIS packages from one Biml file Reusable: Write once and run on any platform Flexible: Start simple, expand as you learn How can Biml help you?
  18. 18. What do you need?

  41. 41. .biml vs .dtsx: human-readable vs ALL THE CODE! (20% zoom)(150% zoom)
  42. 42. Ok, so we can go from Biml to SSIS…
  43. 43. …can we go from SSIS to Biml?
  44. 44. Yes!
  45. 45. Let's reverse-engineer some packages!

  51. 51. …or Create /Add to BimlOnline Project
  52. 52. The magic is in the
  53. 53. Extend Biml with C# or VB code blocks Import database structure and metadata Loop over tables and columns Expressions replace static values Generate, control and manipulate Biml code What is BimlScript?
  54. 54. <# … #> Control Nuggets (Control logic) <#= … #> Text Nuggets (Returns string) <#@ … #> Directives (Compiler instructions) <#+ … #> Class Nuggets (Create C# classes) BimlScript Code Nuggets
  55. 55. <# var con = SchemaManager.CreateConnectionNode(...); #> <# var metadata = con.GetDatabaseSchema(); #> <Biml xmlns="http://schemas.varigence.com/biml.xsd"> <Packages> <# foreach (var table in metadata.TableNodes) { #> <Package Name="Load_<#=table.Name#>"></Package> <# } #> </Packages> </Biml> BimlScript Syntax

  60. 60. How does it work?
  61. 61. Yes, but how does it work?
  62. 62. Yes, but how does it actually work? <# foreach (var table in RootNode.Tables) { #> <Package Name="Load_<#=table.Name#>" /> <# } #> <Package Name="Load_Customer" /> <Package Name="Load_Product" /> <Package Name="Load_Sales" />
  63. 63. Let's generate a lot of packages!
  64. 64. Move common code to separate files Centralize and reuse in many projects Update code once for all projects 1. Include files 2. CallBimlScript with parameters 3. Tiered Biml files Don't Repeat Yourself
  65. 65. Include common code in multiple files and projects Can include many file types: .biml .txt .sql .cs Use the include directive <#@ include file="CommonCode.biml" #> The directive will be replaced by the included file Works like an automated Copy & Paste Include Files
  66. 66. Include Files
  67. 67. Include Files
  68. 68. Include Files
  69. 69. Like a parameterized include or stored procedure File to be called (callee) specifies input parameters <#@ property name="Param" type="String" #> File that calls (caller) passes input parameters <#=CallBimlScript("CommonCode.biml", Param)#> CallBimlScript with Parameters
  70. 70. CallBimlScript with Parameters
  71. 71. CallBimlScript with Parameters
  72. 72. CallBimlScript with Parameters
  73. 73. CallBimlScript with Parameters
  74. 74. CallBimlScript with Parameters
  75. 75. Split Biml code in multiple files Specify tiers by using the template directive <#@ template tier="2" #> Biml files without BimlScript are implicitly tier 0 Biml files with BimlScript are implicitly tier 1 Tiered Biml Files
  76. 76. Biml is compiled from lowest to highest tier to: • Solve logical dependencies • Build solutions in multiple steps behind the scenes For each tier, objects are added to the RootNode Higher tiers can use objects from lower tiers Tiered Biml Files
  77. 77. When working with flat Biml, the <Biml> root element contains collections of elements: <Biml> <Connections>…</Connections> <Databases>…</Databases> <Schemas>…</Schemas> <Tables>…</Tables> <Projects>…</Projects> <Packages>…</Packages> </Biml> When working with BimlScript, the RootNode object contains collections of objects: What is this RootNode?
