The database was set up for me on an external server so there has not been a local database or exporting. I had no trouble with the two previous websites I used Power CMS on using it in the manner I am. Unfortunately I haven't got the access to the database directly just via the connection.
The site is dynamic, when using "Add content to PowerCMS from Dreamweaver there were no issues populating the database.
So no, there hasn't been a need for importing and exporting.
