Datasource Mappings

Datasource Mappings allow you to create and use a friendly name for your OLAP datasource(s). CALUMO will translate these names to the correct server name when queries are made.

All connections will be made using the connection string as specified in the application setting OLAP Base Connection String as well as with other properties as described in Olap Connection String Defaults.


From this page, you can see the following properties for each Datasource Mapping as well as being able to add, modify or delete Datasource Mappings.


There are two actions available for each item:

  • Delete - to delete this entry
  • Show Active Connections - to show a list of active OLAP connections on this datasource ( see below )
