Selecting deployment options

Deploying a world to a client/server architecture on a local or networked drive results in a two-tier architecture, as shown in the following diagram.

Figure 41. Client/Server deployment

An end user accesses a QMF Visionary world by opening its world file (.vis). The end user views a world with QMF Visionary WorldView. QMF Visionary WorldView communicates with the database server through ODBC/QMF-based connectivity.

Note: QMF Visionary WorldView is installed along with QMF Visionary Studio and QMF for Windows. Therefore, the end user must have either of these applications installed to view QMF Visionary worlds with QMF Visionary WorldView.
CAUTION:
Client computers must have a data source configured for every data source used by the QMF Visionary world.

The world file (.vis) contains the published world. It can either be located on the client computers or be accessible from a networked drive; every client computer can have a copy of the same world file, or all clients can access the same world file from a networked drive.

The advantage of keeping the world file on a networked drive is that the world file is automatically updated when it is republished. You need to update the world files on client computers one by one.
