A connection on an Edge site identifies a unique system, whether it's a database, a file share or a REST service.
For JDBC (Java Database Connectivity), you can connect directly from the Edge user interface. When you create a JDBC connection, you will enter your login credentials, which will then be stored for authentication. This means that you will not need to enter these credentials again for any capability that uses this JDBC connection.
If an integration capability does not connect to a JDBC data source, it has to connect on its own by using the information provided by Edge. The connection information is defined and stored as a Connection instance. The connection properties are shown on the Connections configuration page within Edge user interface.
Below is an example of a capability that does not use JDBC to connect:
:
Connection types
All supported connection types are bundled in Edge. You cannot add new connection types, for example Tableau or S3.
