Sometimes a survey may be conducted as a set where each questionnaire has the same axes. For example, a nationwide survey of newspaper readership may be carried out on a regional basis, the data for each region being loaded and processed separately as if each region were an entirely independent survey. However, when all regional tabulations are done, it may be necessary to produce tables based on the population as a whole.

To get information based on all regions, you could create separate tables for each region using Quanvert and then add up the corresponding cells in each table manually. However, by using the multiproject facility, you can link the regional data into a national database so that the required tables can be produced by using Quanvert on that database instead.

How you set up a multiproject database depends on the type of Quanvert:

Create a multiproject database by using the mflip program which is distributed as part of Quanvert Text. See Running mflip.

You create a multiproject database by selecting the separate projects in the Project management dialog box in Quanvert and then clicking the Select button. This invokes the Windows-based version of the mflip program, which is called wmflip. For more information about creating a multiproject in Windows-based Quanvert, see Chapter 16 of the Quanvert User’s Guide.
