Section 2 — Encore Fundamentals
The Encore database core contains information that identifies what a par-
ticular Encore system consists of and its capabilities. The Sharer applica-
tion’s layer shares this information with the various distributed Encore
system applications on the next higher layer. These other applications
(Router, Tie-Line Manager, Panel Server, etc.) use this database information
to control the hardware device components (Router Matrices, control
panels, etc.) residing on the outer device hardware layer. The System
Manager application spans all the layers. It is used to create the information
in the database, set up how it and other applications are accessed by users,
and establish the communications used to span the applications and hard-
ware layers. The first time an Encore system is run, a special login applica-
tion is used to access the System Manager.
Client/Server Architecture
The Encore system can also be viewed as consisting of various software
applications (including the applications described above) that run on
various hardware processors (called Engines). Engines can be Encore
System Controllers, or they may be networked PCs (called Stations, which
is short for workstation). The System Manager can be used to assign which
applications run on which engines. Some of these applications operate
using Client/Server techniques. For example, a Server application residing
on one Engine may provide information and processing resources to Client
applications running on different hardware components. In this way, infor-
mation that needs to be shared with multiple Encore system components
can be managed effectively. An example of this structure is the Panel Server
application, which runs on an Encore System Controller and provides con-
figuration information to multiple Encore control panels, and other sup-
ported control panel models(
