Raining Data Announces the Release of Omnis Studio for SAP

IRVINE, CA. – July 22, 2003

• New Product allows rapid access to SAP data using the Omnis Studio Development Environment

Raining Data Corporation (Nasdaq: RDTA - News), a long-time provider of scaleable, flexible and reliable data management software, today announced the release of Omnis Studio® for SAP® providing a rapid application development environment allowing fast provision of applications accessing SAP data.

Omnis Studio for SAP allows SAP users to leverage their investment by allowing rapid and easy development of fully functional GUI applications for client/server and the web, without compromising their strategic SAP data.

Despite the wide range of modules and industry solutions available from SAP, there is a pressing need by end users to extend SAP capabilities beyond SAP’s traditional metadata-driven customization methodologies. Omnis Studio for SAP allows SAP users to quickly develop, enhance and integrate new or existing applications. Omnis Studio’s strength in building highly scalable, cross-platform applications for client/server and the web is a suitable add-on to SAP and ABAP users who demand fast and cost effective implementations.

“Omnis Studio for SAP offers a sound alternative for integrating and extending SAP applications to multiple environments and database platforms currently supported by Omnis Studio,” stated Birgit Jaeger, Managing Director of Raining Data Germany GmbH. “We have achieved seamless integration between our Rapid Application Development Environment Omnis Studio with the Remote Function Call (RFC) and SAP’s recommended Business Application Program Interface (BAPI). Omnis Studio for SAP fulfills today’s IT demands for cost effective development and rapid time-to-market deployment.”

Omnis Studio for SAP is powered by the Information Integration Adapter certified by SAP and was developed in conjunction with Solonde AG, Hamburg, a SAP solutions provider. Omnis Studio provides rapid client/server and web application development and server deployment under all Windows 32bit, Linux, Sun Solaris, and Mac OS X platforms. Connections to, and data transfer between a wide variety of databases is possible, with native connections provided to most major databases such as Oracle, Sybase and DB2.
