Advantage Database Server Brings Client/Server Revolution to Millions of
Users

NEW DBMS GIVES STRANDED "XBASE USERS" A MIGRATION PATH TO WINDOWS
CLIENT/SERVER

New security features added to leading .DBF Client/Server solution

BOISE, ID (APRIL 23, 1996) -- Extended Systems announced today a new
Windows Client/Server DBMS with enhanced security and data encryption
features. Advantage Database Server 4.1 brings Windows Client/Server
performance and integrity to existing .DBF databases. The Advantage
database engine offers native support for popular Windows development
environments such as Delphi, Visual Basic, Visual C++ and Visual Objects.
Advantage Database Server 4.1 is now shipping. The five-user server is
just $895. The Windows interface is priced at $299.

LEADING APPLICATION DEVELOPERS ABANDON LARGE XBASE MARKET

With the Xbase application development environment slowing, countless
database applications are at risk of being orphaned at a total cost
estimated to be in the hundreds of millions of dollars. Advantage Database
Server, however, extends the viability of existing corporate Xbase
applications by giving them the performance, integrity and security of
Client/Server technology.

Advantage 4.1 allows corporate users to migrate their existing DOS Xbase
applications to a Windows Client/Server environment. With the new expanded
security features incorporated into Advantage 4.1, the index corruption
and data integrity problems that have plagued Xbase users are things of
the past.

USER BENEFITS

 Security      - Protects sensitive information and reduces the
                 threat of corruption
 Integrity     - Eliminates index corruption
 Performance   - Reduces network traffic and improves productivity
 Flexibility   - Supports popular Windows front-end development tools
 Scalability   - Convert from standalone to Client/Server in seconds
 Compatibility - Simple integration into existing applications reduces
                 technical and financial risks

ENHANCED ADVANTAGE SECURITY

To ensure data security, Advantage 4.1 allows network administrators to
"hide" Xbase data files from users that are not accessing the data through
an Advantage application. Now, Xbase data file directories can be "hidden"
by removing all access rights for specificed users-ensuring only Advantage
applications with security enabled have access to these critical files.
This limited access keeps prying eyes away from sensitive data that might
otherwise be accessed from the DOS or DOT (.) prompt. In addition to
protecting sensitive information, this enhanced security also reduces the
threat of corruption.

DATABASE ENCRYPTION FOR NETWORK SECURITY

Advantage 4.1 also supports encryption of one or more fields in one or more
records. It can also encrypt entire database files. Advantage 4.1
encryption provides an easy way to integrate data security over the
network wire.

SCALABLE DATABASE SOLUTION FOR DELPHI, VISUAL BASIC AND VISUAL C++

In cooperation with SuccessWare International, Extended Systems has
developed a scalable Windows database interface called SDE2. Now the same
.EXE will run on a standalone PC or a network without modification or
configuration changes. SDE2 also offers native .VBXs and .DLLs for Delphi,
Visual Basic and Visual C++.

TRANSACTION PROCESSING WITH COMMIT AND ROLLBACK

With its powerful new Transaction Processing System, Advantage 4.1 provides
even more database integrity. In fact, Advantage 4.1 is the only product
that provides true Client/Server transaction processing for .DBF
databases. Building Transaction Processing into your application is easy.
Three simple transaction commands (BEGIN, COMMIT and ROLLBACK) give your
applications the power to ensure multiple update transactions finish
entirely or not at all.

ENTERPRISE-WIDE ODBC CONNECTIVITY

Using an industry-standard Level-2 ODBC driver, Advantage 4.1 allows new
SQL applications and legacy Xbase applications to simultaneously share
data and index files. Now your application can share its data with any
ODBC compliant development or analysis tool. With the Advantage ODBC
interface, one .EXE will work with both .DBF and SQL data sources. Since
it supports user-friendly Xbase command syntax, there is no need for
companies to retrain their developers.

A LOYAL CUSTOMER FOLLOWING

Earlier versions of Advantage Database Server have allowed companies like
UPS, Charles Schwab, Pratt & Whitney, Prudential and Dell Computer to
deploy Client/Server applications without hardware upgrades or data
porting. Advantage has enhanced their existing investment in .DBF data,
front-end legacy applications, development expertise, end-user training
and databases.

Headquartered in Boise, Idaho, Extended Systems has been providing the
Advantage database engine since July 1993. Advantage Database Server is a
scaleable, Client/Server DBMS that allows users to easily migrate their
existing .DBF databases and applications to a Client/Server environment.
With over 75,000 users worldwide, Advantage Database Server has grown to
be a leading migration path for companies looking to migrate PC databases
to Client/Server technology. Contact Extended Systems at (800) 235-7576
