"GCCS is composed of several mission applications built to a single common operating environment networked to support sharing, displaying, and passing of information and databases. The GCCS infrastructure consists of a client server environment incorporating UNIX-based servers and client terminals as well as personal computer (PC) X-terminal workstations; operating on a standardized local area network (LAN). The GCCS infrastructure supports a communications capability providing data transfer facilities among workstations and servers.
The baseline GCCS architecture consists of a suite of relational database and application servers. At most GCCS sites, the relational database server acts as a typical file server by hosting user accounts, user specific data, and site specific files not part of GCCS. The application servers host the automated message handling system, applications not loaded on the database server and other databases.
At each GCCS site, one application server is configured as the executive manager (EM) providing LAN desktop services. It also hosts applications not loaded on the database server. The EM server acts as the user interface providing access to GCCS applications through user identification and discrete passwords. GCCS software applications are categorized into two groups: Common Operating Environment (COE), and Mission applications."
