All known aliases and numbers used by an individual are kept with the individual's record. Erroneous records are corrected by changing the master record, not the intranet copy. All changes made to the master record are uploaded to the intranet system within three minutes. Database queries are constructed by Microsoft's dbWeb package running on the NT server. MS-Access returns query results to dbWeb, which delivers them to the Web browser as HTML documents.
Database schemas define the query and format of pages display on the Web.
End users require minimal computer savvy to operate this system. Training time required to learn how to use the Web-based browser and formulate queries was typically two hours. However, training the site support staff in the administration and management of the intranet system was more challenging. A senior dispatcher and detective learned the intranet system and the databases, and now handle these tasks. The MS-Access database is managed by the central site staff as well.
