Can FSI Viewer and its add-ons be integrated into CMS / database systems?

Of course. Regarding HTML integration and compatibility, FSI Viewer is just like any standard Flash program. So any website, CMS system or application that is capable of integrating a flash movie can be extended by FSI Viewer.

As FSI Viewer can be configured using either XML files or HTTP Queries, automated integration via server-side script can be easily accomplished. See HTTP Queries Tutorial the for more detailed information.
