The selection of an application
interoperability architecture for client/server and
web applications is a strategic decision for any
organization both today and for many years to come.
Application architecture dictates how existing
platforms and tools can interoperate, what new
tools, platforms, and technologies can be adopted,
and the approach for future application
modernization. The following information and
customer comments highlight some important
considerations for selecting an architecture and the
differentiation of the Microsoft architecture.
Capitalize on Your Existing Assets
Your existing OS 2200 Systems, software,
applications, and databases are valuable assets.
Fiscal reality probably dictates that you must
incorporate the use of these assets into any
client/server development or modernization plan.
UniAccess preserves your investment in existing
applications and databases by providing Microsoft
Universal Data Access (ADO/OLE-DB/ODBC) access to OS
2200 applications and databases. Through OLE
DB/ADO/ODBC, UniAccess enables not only language
requests, such as Structured Query Language (SQL),
but also Remote Procedure Calls (RPCs) which invoke
new or existing Unisys TIP transactions or batch
programs. By enabling this high degree of
interoperability between industry leading desktop
and workgroup server technology with your OS 2200
assets, UniAccess allows you to make the most of
your current environment as you invest in the new
generation of technology.
"In this line of business,
seamless interoperability among application
platforms in various internal and external
organizations is mandatory. With UniAccess and
the Microsoft architecture, our Unisys 2200s
have gone from closed and proprietary to one of
the most open systems in the state."
- Don Smith, Director, Strategic
Projects, Texas Department of Human Services
Choice of Virtually ALL Tools and Platforms
As an implementation of the Microsoft architecture,
UniAccess offers a choice of hundreds of industry
leading application development, end-user, and
off-the-shelf client and server products from
Microsoft and hundreds of supporting, industry
leading vendors. The Microsoft architecture is
available on all leading client platforms: DOS,
Windows, Windows NT, OS/2, Apple, and UNIX.
Furthermore, OS 2200 systems may interoperate with
new or existing applications on virtually all server
environments; IBM, HP, DEC, SUN, AT&T, etc.
“Timely and accurate information
is critical to the success of our business. With
UniAccess and the Microsoft architecture, we
have an architecture that will meet our needs
long into the future. With access to Microsoft,
we are tapped into the leading development and
end-user tools, plus the support of many open
platforms. For us, UniAccess and the Microsoft
architecture was the first and only
choice."
- William Krewson, MIS Manager,
Subaru of America
Robustness and High Performance
UniAccess is specifically engineered to provide the
transaction processing qualities you have come to
rely upon from your OS 2200 System. UniAccess is
fully integrated with Unisys OS 2200 systems
software (CMS, TIP, MCB and UDS) and provides the
integrity, security, and performance that your
mission critical applications require.
“Our implementation of
client/server applications was greatly
facilitated by the use of the UniAccess product.
The applications were implemented on schedule,
they performed very well, and they required
minimal training of personnel. From its first
implementation in September 1995, the stability
has been outstanding. The Tabular Data Stream
protocol implemented by AIS provides impressive
performance. Typical queries addressing tens of
thousands of rows return a result with
sub-second response time.”

travel distribution system and among the largest
