Database Connection Manager is a useful tool, which allows you to connect to a local or remote PostgreSQL database for Database Generation, Reverse Engineering, Database Modification, or running SQL scripts.
Database Connection Manager uses connection profiles, which allow you to set all the connection parameters for a specific database only once, and quickly connect to this database later.
The dialog contains a list of available connection profiles. To connect to a database, select one of the defined profiles in the list, and click OK. Connection is assigned to your current diagram, so that each opened diagram could have its own connection.
To add a profile to the list, click the Add button and enter the connection properties using Connection Profile Editor launched.
Click Edit to change the profile connection properties.
To remove a profile from the list, click the Delete button.
You may share your profiles with others and vice versa - for this use Import and Export buttons.
