CAD/CAM/CAE : electronic design automation, 1992 - Archive Server

Host-Dependent—^This is a shared logic
system in which the external workstations'
functions are dependent on a host
computer.
Server—A server is a computer that transparently
provides its resources for use by
other computer systems. It is a system on a
network that provides specific functionality
to other computer systems: the clients.
Functions include file storage, database
access, compute capability, and others. Dataquest
tracks the following major categories
of servers used for CAD/CAM/CAE/GIS
applications:
- Compute Servers—^These systems provide
capabilities for solving numerical problems
(for example, simulations, statistical calculations,
and simultaneous partial differential
equations). System features usually
include high-speed computational capabilities
(for example, veaor and parallel
processing) and large memories.
- Print Servers—^These systems provide
access to printers, specialized printing
applications software, and print spooling
resources to a network.
- File Servers—^These systems provide mass
storage capability to clients on a network.
Services can range from temporary
storage of working files to long-term
backup and archive systems.
- Database Servers—These systems manage
databases as a shared resource to
a network. These servers handle such
functions as physical data storage, data
security, and high-level queries and can
access stored information at the record
level.
Personal Computer—This is defined as a
single-user computer that is distinguished
from a technical workstation by its features
and by the user's potential range of expansion
on the platform. Features found in
technical workstations (such as a virtual
operating system, networking, high-performance
graphics, multiuser/multitasking capability)
are optional rather than integrated by
the manufacturer.
CAD/CAM/CAE—Electronic Design Automation Applications
Revenue/shipments/ASP definitions are as
follows:
• Total factory revenue is defined as the
amount of money received by a manufacturer
for its goods measured in U.S. dollars.
Total factory revenue does not include
revenue that a company may receive from
products that are sold to another company
for resale (OEM revenue).
• Unit shipment is defined as the number of
products delivered (that is, seats).
• Software revenue is revenue derived from
the sale of bundled (part of a turnkey system)
and unbundled software.
• Service revenue is defined as revenue derived
from the service and support of CAD/
CAM/CAE/GIS systems. Service revenue can
be calculated in the tables by subtracting
hardware and software revenue from total
revenue.
Market Share Methodology
Dataquest uses both primary and secondary
sources to produce our market share data.
In the fourth quarter of each year, we survey
all major participants in each industry. Each
vendor is offered the opportunity to self-report
the information required. Although there is a
primary contact for each company, large companies
are surveyed across product lines and
across geographic regions. Thus, there is a
corresponding increase in the number of
contacts at large companies. (Dataquest maintains
a large contact database on all sources
of information). Examples of the job titles of
people contacted for information are the
following:
• President and CEO
• Vice President and General Manager
• Vice President of Marketing
• Vice President, Strategic Product Plarming
• Director of Strategic Planning
• Director of Marketing
