Hi @Kundan 

We have a user guide in our online documentation for working with ONE data as a data source.
https://support.ataccama.com/home/docs/aip/latest/user-guides/one-web-application-user-guide/knowledge-catalog/data-catalog/working-with-data-sources/one-data-connection

The url value should equal the address of your DMM (Data Management Module) on post 8027

Hi @DannyRyan 

Thank you for your response . 

I am not sure which one is the DMM (Data Management Module) . Could you please help me figuring out that .

Some screenshots of the module would help.

Thanks & Regards,

Kundan

Hi @Kundan 
If you enter http://dmm-srv:8027 as the URL.
I have prepared a short video which I hope will be helpful. It shows the whole process of creating a new Data Source connection in the ONE Knowledge Catalog and import & profiling some tables from ONE Data.
