Data source overview page
Open DataBase Connectivity (ODBC) is a standard database access method that allows you to access and modify data from any application, regardless of which database management system is handling the data.
The data to be accessed needs an interpreter (driver), which understands the format of the stored data, and a connection manager that determines how the connection needs to be made.
All this information is stored in a Data Source Name (DSN). For Access database, we use Access DSN and for SQL Database we use SQL DSN.
The types of Data sources supported are:
SQL Data Sources
Access Data Sources
The Overview page displays the maximum number of SQL data sources, and Microsoft® Access data sources that are allowed for the site.
How to go to the Overview page
On the left navigation panel, go to the section Services > ODBC Data Source, and click Overview.
