UNICOM Intelligence Interviewer - Server has the following services:

Interacts with respondents through their browsers.

Runs the majority of the interviewing and Project Management software, including the UNICOM Intelligence Data Model. If you install this service on a number of computers in a cluster, the installation procedure makes the first computer hosting the service the Primary UNICOM Intelligence Interviewer - Server and the second computer the Secondary UNICOM Intelligence Interviewer - Server.

Hosts Internet Information Server (IIS) and stores UNICOM Intelligence Interviewer - Server Admin and all UNICOM Intelligence Interviewer - Server Admin and UNICOM Intelligence Interviewer - Server activities.

Runs SQL Server and stores the response data. Might also store the sample and quota databases. The UNICOM Intelligence Interviewer - Server installation procedure does not install anything on computers running just this service.

Installed on a client computer. Includes the UNICOM Intelligence Data Model and Activate components. The Scriptwriter Service is typically used by scriptwriters who do not have access to UNICOM Intelligence Interviewer - Server Admin via their browsers.

Depending on the size of your installation, you can install several services all on one computer, or install each service on a different computer, or install the same service on a number of computers.

If you install on more than one computer (that is, a “cluster installation”), install them in this order:

Finally, install the Scriptwriter Service where necessary.

Very small sites might use a single computer for all functions, so you can install the Scriptwriter Service, Web Service, Interview Service, Accessories Service, and SQL Server all on that computer. Larger sites might want to use this type of setup for testing purposes, while setting up their main system using several computers.

Larger sites might have a database computer running SQL Server, and a Web and interview computer running IIS, the Web Service, Interview Service, and Accessories Service.

Very large sites probably have separate computers for each service except the Accessories Service. This will be installed on the computer running the Interview Service.

Generally, scriptwriters access the activities they require by connecting to UNICOM Intelligence Interviewer - Server Admin by using a web browser. If your site has scriptwriters who work off-line and do not always have access to UNICOM Intelligence Interviewer - Server Admin, you can install the Scriptwriter Service on those computers, and the scriptwriters will be able to create, compile, and activate questionnaires using desktop activities.

UNICOM Intelligence Interviewer - Server allows all computers to be in the same domain or workgroup, or you can have the database server in one domain with the computers running the other services in another domain.

If you use more than one domain, the domains must trust one another. Consider carefully how your site will be configured before starting to install UNICOM Intelligence Interviewer - Server, so that you install the correct services on each computer.
