The Relational Data connector API provides a set of pre-defined connection attributes that you can use for the connector. You can enable any of the pre-defined attributes to use for the connector. When you enable a pre-defined attribute, you can set its default value or mark it as a required attribute. You can disable attributes that are not applicable to the relational database you want to connect to.

You can also define custom connection attributes for the connector. Define a custom attribute if the relational database has a connection requirement that is not represented by one of the pre-defined attributes.
