Biml Annotations and ObjectTags

Biml Annotations and ObjectTagsBiml objects have many built-in attributes. For example, all Tables have SchemaName and all Packages have ProtectionLevel. When your Biml solution starts to grow, you will quickly see the need for adding additional metadata that can be used in other Biml files. A common use case in Data Warehouse Staging projects is to store the source schema and source table name on your staging table objects. This allows you to use the source metadata in a higher tier Biml file that generates the SSIS packages to load the tables. To store and use this additional metadata, you can use Biml Annotations or ObjectTags.

Biml Annotations and ObjectTags are both Key/Value pairs. Annotations are String/String pairs intended for storing simple text metadata, while ObjectTags are String/Object pairs that can also store more complex metadata in .NET objects.

Don’t Repeat Your Biml – Tiered Biml Files

Biml (Business Intelligence Markup Language) - Tiered Biml FilesMany Biml solutions start off very simple, with just a single Biml file that generates a few SSIS packages. Most developers quickly see the need for a more complex solution for multiple sources. One way to reuse code and apply the Don’t Repeat Yourself software engineering principle in Biml is to use Tiered Biml Files.

In addition to using Tiered Biml Files, there are four other main ways you can avoid repeating your Biml code:

In this post, we will look at how to use Tiered Biml Files.

Don’t Repeat Your Biml – C#/VB Code Files

Biml (Business Intelligence Markup Language) - C#/VB Code FilesDo you use C#/VB classes and methods in your Biml projects? One solution is to create class nuggets <#+ … #>, but they can only be used in their containing Biml file. You can move class nuggets to separate files and include those files, but a more elegant solution is to use C#/VB Code Files.

In addition to using C#/VB Code Files, there are four other main ways you can avoid repeating your Biml code:

In this post, we will look at how to use C#/VB Code Files.

Don’t Repeat Your Biml – Include Files

Biml (Business Intelligence Markup Language) - Include FilesAre you using Biml so you won’t have to do the same tasks over and over and over again in multiple SSIS packages? If so, you probably don’t want to write the same Biml code over and over and over again either. Instead, you can move common code to separate files, centralize and reuse these files in many projects, and update code in one file to make changes to all projects. One of the ways to apply this Don’t Repeat Yourself software engineering principle in Biml is to use Include Files.

In addition to using Include Files, there are four other main ways you can avoid repeating your Biml code:

In this post we will look at how to use Include Files.
