In the previous article SharePoint 2016/2013: OData Connector for Tableau Reports, I had explained you the implementation details of connecting SharePoint with Tableau using Odata Connections.
Since this approach was not confident and was not working for me as expected I have developed another reusable Add-in to achieve data sync between SharePoint & Tableau.
I call this Add-in as “SharePoint –Tableau Sync Manager”. To understand this Add-in better you can refer to the below Technical Diagram section
Following is the brief description of each of the components of this add-in-
Task Scheduler: This component is responsible to execute Sync Service at a defined frequency.
Sync Service: This component will perform following operations
- Provision staging database, though this is optional and can be done directly at database level
- Query SharePoint using CSOM/REST API End Points and sync it with staging database which is a SQL Server based database
- Generate logs with differential changes
- Send Email Notifications to Tableau Report Administrator/Owners
Analytics Staging Database: This database will store the data retrieved from SharePoint and act as primary data source for Tableau Report.
Tableau Report: This could be any Tableau Report based on the query from staging database.
In order to setup this demo, I have created a SharePoint List “MyLocations” that will hold locations data as shown below:
Staging database is provisioned with a Table “My_Locations” that is having corresponding columns to store data from SharePoint as shown below
Once database has been created we can write any required SQL query to fetch the data. In this case I have used a simple select statement to fetch all the data from the table
Now lets’ look into the Sync Service code that will talk to SharePoint using CSOM/ REST API End Points
Step 1 involves connecting to SharePoint List by using usual PowerShell CSOM technique
Step 2 involves connecting to staging database and deleting the existing content from the “My_Locations” Table
Step 3 involves reading data from SharePoint List and inserting it into staging table
Step 4 involves an exception handler that will send notifications to the process administrators in case if any error occurred during the Sync Process
Additionally we can generate differential logs and success notification to the report owners or may extend this layer to connect with other sources as well.
So that is all for the code.
Once it gets executed successfully we can see data has been synced from SharePoint to Staging Database
Go to database run the select query again to see if data synched successfully
Once data source is ready we can start designing the Tableau Report using Tableau Desktop by taking “Microsoft SQL Server” as connection.
On connecting with SQL Server specify the query to fetch the data for the report as shown below:
Once data connection is successful we can see data surfacing to Tableau Designer
Now you can design the report of your choice based on this data, for this demo I am presenting information as Geo Map which is most suitable for the kind of data that we have in “MyLocations” Lists in SharePoint
Based on this report I have added a dashboard and publish this dashboard to Tableau Server
This will be the final look of Tableau Report executing in browser
Now lets’ consider that we need to add another location type and to do so follow the Steps below:
- Access to SharePoint Site
- Add List Item to “MyLocations” List as highlighted below
Once data has been added/updated to SharePoint, Sync Manager will pick-out all the changes and sync back to Staging Database as per defined schedule
Once Sync Manager executes successfully, just refresh the report by using “Refresh” button on the report
And sure enough you will see the changes reflected on the report
We can extend this Sync Manger to cater even more advanced scenarios, which I may cover in some of the upcoming articles.
That is all for this demo.
