When you create a connection, you define general properties and database properties.
Configure general properties that are relevant for all database connection types, such as the business application and application version that you want to archive data from.
Configure database properties that are relevant to the source database, such as how the archive job connects to the source and how the job archives data from the source. You can also specify properties to improve the archive job performance. The connection properties depend on the connection type that you choose for the database.
When you create an archive project, you select the source connection. The archive job uses the attributes that you defined for the connection.
