February 11, 1992-Laurel, MD-XDB Systems, Inc., the SQL technology leader, expands its relational database management product line by unveiling XDB-LINK at NetWorld '92, a new software package that permits PC applications to transparently access mainframe DB2 data. "Developers can use XDB-Workbench as well as the interactive XDB tools to query, update, report, browse and enter data directly to DB2," states Robert Strom, XDB's Senior Development Manager. With XDB-LINK it is now possible to develop cooperative processing applications in order to use MIS resources more efficiently. For example, applications and data that reside in distributed areas can be viewed as a single data center. The XDB-LINK product consists of two components: XDB-LINK Gateway, which resides on the PC, and the XDB-LINK Host, which resides on the mainframe. These components communicate via LU6.2 protocols to satisfy DB2 SQL requests originated from the PC. The XDB-LINK works with IBM's CICS/APPC product and VTAM. XDB-LINK is based on the client-server architecture and supports DOS, OS/2, and Windows clients. In a development environment, the XDB-LINK product extends systems level testing to the PC environment by providing access to mainframe production data. In a production environment, XDB's application tools (XDB-Workbench, XDB-Tools, XDB-C) and LAN applications can now access data residing in mainframe DB2 as a database server. One significant advantage of the XDB-LINK package is increased productivity. The data transfer procedure has been streamlined since developers can now transfer data between the PC and the mainframe in one step. In addition, data access using XDB-LINK's bulk fetch processing feature is comparable to local 3270 access. Mike Meyer, Principle Systems Associate with Mutual Benefit Life Insurance Company in Newark, NJ said, "With the LINK's bulk fetch processing feature I can save a significant amount of time and resources required to fetch multiple rows from DB2." IBM is scheduled for commercial release of their Distributed Relational Data Architecture (DRDA) standard next year and XDB intends to supports DRDA. XDB Systems is committed to providing quality relational database management products and services. The price range for the XDBLINK is $21,000 to $36,000 depending upon a company's mainframe CPU size.

The XDB-SERVER is a high performance, multi-user database system that brings the power and integrity of mainframe database systems to LANs. The core of XDB's product line is the 100% DB2 compatible Engine. Now with the XDB-SERVER for OS/2 version 2.41, DB2 applications become portable to client-server platforms. Since the XDB-SERVER is network independent, DB2 compatibility can exist on multiple platforms and operating systems. The main benefits of the XDB-SERVER for OS/2 version 2.41 are increased power and performance. Rusty Fiste, XDB's Director of Development, states, "XDB's new, enhanced SERVER for OS/2 obtains significant performance gains because of its improved internal buffer management system which minimizes disk accesses." Multiple physical disk volumes are now supported. Now developers can utilize multiple disk volumes to separate various data objects like indices and databases thereby decreasing the amount of time required to retrieve data. The size of a database is also no longer limited by the size of one OS/2 disk volume. In addition, the XDB-SERVER for OS/2 version 2.41 has greatly enhanced its query optimization. The XDB-SERVER takes maximum advantage of OS/2 technology. One of the Beta sites chose XDB-SERVER because they wanted DB2 compatibility on their PC LAN. Igor Kruglyak, Assistant Vice President & Systems Architect with Merrill Lynch in Somerset, NJ, states, "We have many users that need to share DB2 data and the XDB-SERVER provides the fully DB2 compatible technology for mainframe applications to migrate to the LAN environment." -------------------------------------------------------- February 11, 1992 - Laurel, MD-XDB Systems, Inc., the SQL technology leader, will be featuring Version 2.41 of the XDB-Workbench. The new engine supports both DOS and OS/2 and is designed to provide an unprecedented level of compatibility with IBM's mainframe relational database DB2. The XDB-Workbench 2.41 enables COBOL programmers to develop, test, and run DB2 applications in an inexpensive and friendly PC environment. XDB has added numerous functions to their new version of their Workbench 2.41 in order to fine tune their compatibility with DB2. Rusty Fiste, XDB's Director of Development says, "This latest version of our workbench delves deep into the distinctive characteristics of DB2." XDB's reserved words were also made fully compatible with DB2. "This release further underscores our commitment to ensure 100% compatibility between XDB's Workbench and DB2," states Rusty Fiste. "XDB's Workbench version 2.41 is well suited for downsizing mainframe DB2 applications, where DB2 compatibility is a crucial consideration. XDB has made a remarkable commitment to capture the subtle intricacies of the DB2/SQL engine," says Jonathan Sayles, Director of Education Services for The Systems Group and a nationally recognized author on relational technology. Rick Slade, Senior Research Analyst at Sara Lee in Winston-Salem, North Carolina said, "I chose the XDB-Workbench for PC-based development because no recoding would be required when we moved our project back up to the mainframe." In addition to DB2 compatibility enhancements, other Product enhancements include additional referential integrity clauses, date/time functions, string functions, numeric functions, table privileges, and database privileges. The XDB-Workbench is the first PC SQL DBMS to provide the rigorous referential integrity constraints including cascading update, a fundamental data manipulation function that involves modifying data records in a continuous series so that all corresponding data is brought up to date. XDB Systems sets the standards for database management. Following the release of the XDBWorkbench Version 2.41, XDB Systems, Inc. will be releasing their new XDB-LINK product and their new version of the XDB SERVER engine for OS/2. The XDB-LINK permits PC applications to directly access mainframe DB2 data. Developers can use the interactive XDB tools to query, update, report, browse and enter data directly to DB2. The XDB SERVER for OS/2, a multi-user database system that brings the power and integrity of mainframe database systems to LANS, will feature increased power and memory size enhancements. -------------------------------------------------------- XDB Systems, Inc. offers high performance database solutions that are powerful, easy to use, and compatible with industry SQL standards. The XDB-Workbench Version 2.41 makes your PC a complete DB2 applications development machine. The list price of the XDB-Workbench in $1500.00.
