Participant (sample) records and case data are two of the most sensitive areas of a project so you will probably want to protect them against unauthorized access. Sample management scripts are also sensitive but for a different reason. Being the equivalent of programs, sample management scripts have the potential to provide unauthorized access to UNICOM Intelligence Interviewer files and databases simply by containing statements that read those files. UNICOM Intelligence Interviewer and UNICOM Intelligence Interviewer - Server Admin provide tools for controlling access to the following files and databases:

You can control who has access to the servers that store your sample data. You can also restrict access to databases and individual tables by UNICOM Intelligence Interviewer - Server Admin role name so that, for example, all users who work on projects for customer A and are part of the CustomerA role can access the sample for customer A's projects but not for any other customer. For more information, see Controlling access to sample data.

Most users need only the ability to select the sample management script that will be used for their projects, so you can restrict editing permission to just those users who really need to be able to change scripts. For more information, see Controlling access to sample management scripts.

A number of UNICOM Intelligence Interviewer activities provide access to the case data for analysis, review, or export purposes. By setting the appropriate permissions on these activities you can control who has access to the case data. For more information, see Controlling access to case data.

You can also define additional restrictions for the Launch activity so that you can control which users can create new databases, and which users can activate projects using each database. For more information, see Project (case data) databases.

Records should be in the ACTIVE queue only when an interview is occurring. However, participant/sample records can sometimes remain in the ACTIVE queue when Microsoft Internet Information Services, or one of the UNICOM Intelligence services, stops unexpectedly. These records cannot be restarted by Web respondents and can only be retrieved by phone interviewers if the participant identifier is known (which makes these records unusable). Two Microsoft SQL stored procedures are used to identify records that erroneously remain in the ACTIVE queue, and move them to another queue. For more information, see Recovering ACTIVE sample records.
