Raining Data Corporation to Demonstrate Mid-Tier XML Data Server For Rapid Information Aggregation at SIA 2003

Raining Data to Showcase Its TigerLogic XML Data Management Server During the SIA 2003 Technology Management Conference At Booth # 4200, June 17 - 19 in New York

IRVINE, Calif., June 5, 2003 -- Raining Data Corporation (Nasdaq: RDTA), a long-time provider of scalable, flexible and reliable data management software, will be demonstrating its TigerLogic XDMS mid-tier operational data server at the SIA 2003 Technology Management Conference and Exhibit, June 17-19, 2003 in New York at Booth #4200, Americas Hall #2, Level 3 at the Hilton New York hotel. The company is also sponsoring the conference registration equipment throughout the event.

Raining Data will showcase how its TigerLogic XML Data Management Server (XDMS) helps financial services providers to easily aggregate data from multiple structured and unstructured sources helping XML-enabled Java and .NET applications access more data faster. Specifically, the TigerLogic XDMS is a mid-tier operational data server that integrates and transforms data of any type or structure into XML and then stores it in the mid-tier -- between Web-enabled clients and back-end operational systems -- to satisfy requests for commonly needed aggregated information. As a result of this innovative approach, TigerLogic XDMS can deliver 10 times faster XML queries through its patent-pending profiling and indexing technology. By expediting XML data delivery, the TigerLogic XDMS gives trading desk and customer care professionals the additional intelligence to rapidly make better-informed and more profitable decisions.

In addition, TigerLogic XDMS enables easier support for a number of financial services XML standards, including XBRL, RIXML, MDDL and others, to simplify data abstraction and aggregation, as well as to produce significant cost savings from reusable views and off-loaded back-end processing.

Raining Data will be providing attendees of the SIA 2003 Technology Management Conference free copies of recently published research reports that detail the TigerLogic XDMS approach and its importance to strategic information management architecture in the financial services industry, including:
