Enterprise C/S development to get performance boost; XVT introduces direct connectivity to IBM's DB2; integrates multiple database support into cross platform GUI tools.SAN FRANCISCO--(BUSINESS WIRE)--May 2, 1995--(DB/EXPO)--XVT Software Inc. Tuesday announced two new products that will allow application developers to build high-performance client/server applications that can directly access DB2 from any popular GUI (Graphical User Interface) A graphics-based user interface that incorporates movable windows, icons and a mouse. The ability to resize application windows and change style and size of fonts are the significant advantages of a GUI vs. a character-based interface. client, as well as easily connect clients to other popular databases, such as Oracle, Sybase, and SQL Server An earlier relational DBMS from Sybase and from Microsoft. Sybase introduced SQL Server in 1988 for various Unix versions. In that same year, with help from IBM, Sybase created an OS/2 version that Microsoft licensed and branded as Microsoft SQL Server. . The new products are intended to make XVT's Development Solution for C (DSC (1) (Digital Signal Controller) A microcontroller and DSP combined on the same chip. It adds the interrupt-driven capabilities normally associated with a microcontroller to a DSP, which typically functions as a continuous process. See microcontroller and DSP. ) more appealing to corporate application development managers who have been frustrated with the performance and lack of scalability of 4GLs and emulated cross-platform tools. They also provide the industry's first client-to-mainframe software development solution that directly accesses DB2 rather than using gateways, transaction managers (such as CICS (Customer Information Control System) A TP monitor from IBM that was originally developed to provide transaction processing for IBM mainframes. It controls the interaction between applications and users and lets programmers develop screen displays without ), or error-prone database replication. "Clients have been able to connect to mainframes indirectly for quite a while, but they've had to give up peformance to do it," said XVT's founder and CTO (Chief Technical Officer) The executive responsible for the technical direction of an organization. See CIO and salary survey. , Marc Rochkind. "By providing direct access to DB2 data -- and I mean direct -- these database connectivity solutions make high-performance, truly database-aware client applications possible for the first time. They're not just new products for XVT (EXtensible Virtual Toolkit) A C++ developer's toolkit for creating user interfaces across multiple environments from XVT Software, Inc., Cary, NC, a division of Providence Software (www.xvt.com). . They constitute a major advance in client/server technology." The products from XVT are Shadow Direct, for direct DB2 access, and XVT DBAware Client Tools, for use with DSC. Shadow Direct lets developers build desktop applications that run transparently with data retrieved directly from DB2 databases, without going through gateways, CICS, or any other transaction manager. This direct access to mainframe data lets the client application take full advantage of MVS (Multiple Virtual Storage) Introduced in 1974, the primary operating system used with IBM mainframes (the others are VM and DOS/VSE). MVS is a batch processing-oriented operating system that manages large amounts of memory and disk space. multi-tasking, so desktop users enjoy the fastest possible performance. Unlike other currently available products, which burden systems by forcing database updates to be committed as they occur, Shadow Direct lets client applications combine database updates and control when they're rolled back to the mainframe. Shadow Direct provides all the diagnostic facilities, monitoring capabilities, and built-in error checking required for large-scale client/server and client/server-server data processing data processing or information processing, operations (e.g., handling, merging, sorting, and computing) performed upon data in accordance with strictly defined procedures, such as recording and summarizing the financial transactions of a . Shadow Direct also provides an ODBC (Open DataBase Connectivity) A database programming interface from Microsoft that provides a common language for Windows applications to access databases on a network. driver to interface with XVT DBAware Client Tools. XVT DBAware Client Tools provides components that manage concurrent retrieval and updating of database information on heterogeneous databases, including DB2, Oracle, Sybase, SQL Server, and many others. Because it includes XVT's DSC, which delivers native performance on all popular platforms, it offers the most productive C-language solution available for building fast, scalable, database-aware client applications. DBAware Client Tools supports the ODBC database connectivity standard and is therefore compatible with any ODBC compatible drivers. Similar functionality to that found in XVT DBAware Client Tools is also under development for use with XVT Development Solution for C++. This product will be released at a later date. Pricing and Availability Shadow Direct and XVT DBAware Client Tools are available by calling XVT Software. Shadow Direct is available through XVT in North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. . Both products are currently shipping. Shadow Direct supports Microsoft Windows See Windows. (operating system) Microsoft Windows - Microsoft's proprietary window system and user interface software released in 1985 to run on top of MS-DOS. Widely criticised for being too slow (hence "Windoze", "Microsloth Windows") on the machines available then. , Windows NT (Windows New Technology) A 32-bit operating system from Microsoft for Intel x86 CPUs. NT is the core technology in Windows 2000 and Windows XP (see Windows). Available in separate client and server versions, it includes built-in networking and preemptive multitasking. , OSF/Motif, and OS/2 clients. Shadow Direct's mainframe software is priced per MVS Host starting at $15,000. XVT DBAware Client Tools is available for Microsoft Windows, Windows NT, OSF/Motif, OS/2, and Macintosh. DBAware is licensed on a developer-seat basis for $4,500 on personal computers and and $9,850 on workstations. Special pricing is available for current XVT DSC customers who want to upgrade to DBAware Client Tools.
