U.S. Coast Guard Common Operating Environment (USCG COE)
MOTIF. The Open Group's MOTIF(r) Window Manager is the graphical user
interface built on X Windows. This is the standard windowing interface for
USCG platforms running the UNIX operating system.
With the Coast Guard in a Windows NT environment, procurements should stipulate the
WIN32 standard wherever practicable. However, if interoperability is needed with an agency or
organization that uses X-Windows, the procurement must consider the X-Windows standard. FIPS
PUB 158-1 addresses layers 0, 1, and 2 of the User Interface System Reference Model (UISRM)
which is based on the Massachusetts Institute of Technology's X Window system. Work is still in
progress on Layers 3, 4, 5, and 6 and has not progressed enough to include specifications in this
model on those layers.
Menus - Allows for the generation of custom menus within the desktop environment
and the customization of existing applications in the desktop.
Icons - Allows for the creation of pictorial representations of applications associated
with the information which the operating system needs to execute the application.
3.3. Infrastructure Services Layer
Infrastructure Services are largely independent of any particular application.
3.3.1. Management Services.
The Management Services functional element includes network and system
management, and security administration.
3.3.2. Communications Services.
The Communications Services functional element provides facilities for receiving and
sending data out of the system to interact with other message and data systems.
3.3.3. Distributed Computing Services.
The Distributed Computing Services functional element provides the infrastructure
necessary to achieve true distributed processing in a client/server environment.
3.3.4. Presentation Services.
The Presentation Services functional element is responsible for direct interaction with the
human whether that is through windows, icons, menus, or multimedia.
3.3.5. Data Management Services.
The Data Management Services functional element includes an application-independent
capability to maintain and administer data through a COTS relational database management
system. It also provides the user with file management in a distributed environment through
a graphical interface to the file system, including "drag-and-drop" functionality between
objects and between cooperating client applications, and a general file type association
database. USCG COE DBMS products must support data spread across multiple sites.
