NuMega DevPartner Studio 6.5 Targets Performance and Reliability Issues in Windows DNA 2000 and Java Applications

FARMINGTON HILLS, Mich.-- February 8, 2000 -- Compuware Corporation (NASDAQ:CPWR) today announced NuMega DevPartner Studio 6.5, a major upgrade to its award- winning suite of software development productivity tools for Microsoft (NASDAQ: MSFT) Windows developers. DevPartner Studio 6.5 extends its core support for Visual C++, Visual Basic and Java by adding new support for Windows DNA 2000 and web technologies. DevPartner Studio 6.5 introduces the first distributed profiling and coverage tools with multi-language, multi- tier support. By automatically finding software errors, performance bottlenecks and untested code, DevPartner Studio 6.5 accelerates software development and improves application performance and reliability.

"Finding software errors and performance problems in distributed applications is a challenging and time consuming task," said James Moore, lead systems developer at Nabisco Corporation. "DevPartner Studio helps our developers understand and resolve these problems quickly by providing visibility into all of the components in our distributed applications."

DevPartner Studio 6.5 includes developer productivity tools for source code analysis, runtime error detection, performance profiling, memory profiling and code coverage analysis. These tools have been enhanced to support Microsoft Windows DNA 2000 products and technologies including Visual Studio, COM+, Microsoft Transaction Server (MTS), Microsoft Message Queue (MSMQ), Internet Information Services (IIS), Visual Basic WebClasses, Active Server Pages (ASP) and ActiveX Data Objects.

"We are very pleased with Compuware's strong commitment to Windows DNA 2000," said Tod Nielsen, vice president of developer marketing at Microsoft. "Over the years, Compuware has consistently helped Visual Studio customers to be more productive. NuMega DevPartner Studio 6.5 is a great complement to Visual Studio, helping developers to quickly build Windows DNA 2000 applications."

DevPartner Studio 6.5 is optimized for development teams using Microsoft Visual Studio to create Windows DNA 2000 applications with Visual Basic, Visual C++, Java and HTML. With the new support for JavaScript, JScript, VBScript and Active Server Pages, DevPartner Studio 6.5 helps developers understand how components in a Web application interact and work together. Fully integrated into the Visual Studio development environment, DevPartner Studio provides extensive support for Windows 2000, Windows NT, Windows 98/95 and Windows CE.

DevPartner Studio can correlate and analyze runtime data collected from distributed components on multiple systems, and present an end-to-end view of an application's overall performance and coverage. Developers can now understand exactly when each distributed component or script executed and identify performance bottlenecks and untested code. DevPartner Studio provides this information at many levels of granularity, from component level to individual lines of script or source code across all its supported languages and environments.

"Software reliability and time to market are two of the most pressing challenges for Web and e-commerce development teams," said Joe Wurm, Vice President and Lab Director for the NuMega product line. "With this release, we are extending the capabilities of DevPartner Studio specifically for developers of distributed applications. This is another example of how Compuware is helping companies accelerate the deployment of reliable e- commerce applications."

NuMega DevPartner Studio 6.5 will be available in April 2000.
