Real Time Data Warehouse ETL

To implement my Service Broker ETL API, I started with the basic code/framework provided by Eitan Blumin in this blog post.  He provides a good basic framework for the setup of Service Broker and an explanation of the installation scripts.  To learn more on the basic framework and scripts to implement Service Broker please refer to his post.

In this post, I’m going to provide his scripts for the basic installation, with some modifications, to work with the Dynamics GP database and Solver’s BI360 data warehouse. I will also be using his scripts for my modified stored procedure, usp_AT_iGLETL, that provides the logic of the ETL process from Dynamics GP’s general ledger table, GL20000, to Solver’s BI360 staging table.

General Workflow

Eitan’s general Service Broker workflow looks like this:

1.     The user performs an UPDATE operation on a table. In my case with the modifications in place, the posting of a General Ledger batch within Dynamics GP will be the UPDATE operation on the GL20000 table.

2.     An AFTER INSERT trigger on the table is fired. This trigger compiles the contents of the INSERTED and DELETED tables into XML parameters, creates a Service Broker message and sends it to a queue. The original transaction immediately returns.  The modifications to the AFTER INSERT trigger pass the usp_AT_iGLETL stored procedure into the SB_AT_Fire_Trigger stored procedure.

3.     The Service Broker service fires up and processes the messages in the queue independently of the original transaction. It opens up a transaction that will pull the message out of the queue, execute a relevant stored procedure that will use the XML data previously taken from the INSERTED and DELETED tables, and implement the relevant logic within the usp_AT_iGLETL stored procedure.

Service Broker Framework Installation and Usage

The installation script provided below implement a generic Service Broker framework which will allow you to use it for any table without any changes to the installed objects. The framework will work like this:

1.     Run the “Step1_SB_AT_Installation” script on the Dynamics GP company database where you want the asynchronous triggers.

2.     Run the “Step2_GP_GLTable_Trigger” script on the Dynamics GP company database to create the AFTER INSERT trigger on the GL20000 table.

3.     Run the “Step3_GP_ETL_Logging” script to create the basic framework for logging the Service Broker ETL process and error logs.

4.     Run the “Step4_BI360_f_Trans_GL_Staging_Table” script to create the staging table for in BI360DW database.

5.     Run the “Step5_ETL_StoredProcedure” script on the Dynamics GP company database to create the stored procedure, usp_AT_iGLETL, with the ETL logic.

You should now have in place a “Near Real Time ETL” process in place to handle the loading of data from Dynamics GP to staging table within Solver’s BI360DW data warehouse database.  You could then use the same logic and scripts above to handle the loading of the data from the staging table to the f_Trans_GL table within the BI360DW database.  In my tests of the implementation outlined above, I was able to post a 350 line batch within Dynamics GP and load the staging table within five seconds.

I hope this helps you with the basic understanding and installation of a Service Broker as an ETL tool in loading your data warehouse.  If you need additional help kick starting your organization into becoming data driven organization by exploring your Business Intelligence, BI360, Power BI, Microsoft Dynamics GP and CRM needs, please contact KTL Solutions at 301.360.0001 or you can email [email url=”info@ktlsolutions.com” class=””]info@ktlsolutions.com[/email]
