RAINING DATA ANNOUNCES SUPPORT FOR
MICROSOFT VISUAL STUDIO ”WHIDBEY”

IRVINE, CA. – October 28, 2003

Pick Data Provider for the Microsoft .NET Framework to Utilize
Latest Productivity Enhancements in Visual Studio “Whidbey”

Raining Data Corporation (Nasdaq: RDTA - News), a long-time provider of scalable, flexible and reliable data management software, today announced future plans for Pick Data Provider for the Microsoft .NET Framework (“PickDP.NET”) to support Microsoft Visual Studio “Whidbey.” Raining Data’s Pick Data Provider for the Microsoft .NET Framework is seamlessly integrated with Visual Studio .NET 2003. The productivity enhancements for the developer community, specifically in code reduction, offered by Visual Studio “Whidbey”, will have broader appeal with ISV and corporate developers for whom timely delivery of client/server, Web or Web services solutions is critical.

“We welcome any efforts that deliver higher productivity tools and measured ROI for application development,” said Ron McPherson, Founder/President of New England Computer Solutions in Peabody, Massachusetts. “The combination of Pick Data Provider for the Microsoft .NET Framework and Visual Studio .NET 2003 has enormous potential for legacy application integration of IBM UniVerse database applications with modern technology. We have already seen a 60-70% code reduction in the re-development of our UniVerse based manufacturing job control application to the Microsoft .NET Framework. Visual Studio “Whidbey” can only accelerate these efforts.”

“Enhancements in application development tools need to focus on providing increased developer productivity, Visual Studio “Whidbey” delivers on that need,” said Mario Barrenechea, SVP of Worldwide Sales & Marketing at Raining Data Corporation. “In the IBM UniVerse, IBM UniData and our Pick D³ markets, there are hundreds of “black-box” applications that have limited access to new technologies. End-users are demanding better tools that will extend their existing applications. By building non-intrusive Web and Web services applications based on PickDP.NET and Visual Studio .NET 2003, developers can tap into existing application resources and data natively, without compromising the integrity of their legacy applications.”

“Raining Data offers a powerful solution to extend legacy Pick and Pick-based applications to the .NET Framework.” said David Lazar, director in the Developer Platform and Evangelism Division at Microsoft Corp. “We are excited that Raining Data is assisting well-established organizations using Pick databases to extend their applications to take advantage of Visual Studio ‘Whidbey.’”
