RAINING DATA ANNOUNCES MAJOR NEW 3.0 RELEASE
OF TIGERLOGIC XML DATA MANAGEMENT SERVER

IRVINE, CA. – June 19, 2007

• High Performance Native XML Data Management Server with Self-Defining Data Structure
• XA Transaction Compliant with Enhanced Node Level Update and Locking
• Cache Adapter Provides Cached Views, with Refresh Policies, from any Data Source
• Supports up to 64 GB of In-Memory Cache from any Data Source
• Native Geospatial Support of XML Messages
  

Raining Data Corporation (Nasdaq: RDTA), a long-time provider of scalable, flexible and reliable data management software, today announced the beta availability of its new 3.0 release of TigerLogic^® XML Data Management Server (XDMS) software, which supports the January 2007 W3C XML Query 1.0 specification. TigerLogic XDMS includes the TigerLogic high performance native XML database and TigerLogic XQuery engine. Unlike a relational database, the TigerLogic XML database handles multiple XML structures in the same collection and automatically evolves the structure as new data is introduced, providing excellent interoperability capabilities for dynamic data sources. TigerLogic XDMS provides full XA transaction compliance (two-phase commit) with true node level update and locking.

TigerLogic XDMS 3.0 introduces the new cache adapter, which provides cached views from any data source, including Web Services, with refresh policies, exposing defined views of data for specific application requirements and off-loading the need to always query the back-end data source. Users can also configure up to 64 GB of in-memory cache, for accelerated query performance. TigerLogic XDMS 3.0 supports the Geographic Markup Language (GML) to model geospatial data in XML and uses GiST-based spatial indexing for consolidated and efficient search. In addition to the existing TigerLogic XDMS APIs, TigerLogic XDMS 3.0 now supports new client APIs: XQJ (JSR 225 – XQuery API for Java), ADO.NET (native .NET support) and an embedded HTTP server supporting native Web Services (for ease of deployment of any XQuery as a Web Service). For enhanced reliability, TigerLogic XDMS introduces replication (which supports up to eight replicated subscriber nodes from a single publisher node) and a two-node High-Availability cluster for failover.

After performing an extensive evaluation of database vendors, Nextrials, an Electronic Data Capture software company for clinical trials in the life science industry, selected TigerLogic XDMS 3.0. According to Bob Lyons, Chief Technology Officer of Nextrials, “If you spend 90% of your time dealing with XML format, reading it, rendering it, etc., then why fight and store your data in some other representation? We needed to manage large XML documents and only TigerLogic provided high performance XML data management with two-phase commit transactional compliance and true node level locking for concurrent updates. Additionally, we can now store an entire clinical trial study in-memory for even greater performance.”

Cache Adapter
There is a need in many large organizations to bring together data from disparate data sources and make it available to data consumers. Mid-tier cache enables performance acceleration and mitigates contention on back-end systems. The TigerLogic XDMS cache adapter provides the ability to automatically cache any data addressable by the TigerLogic XDMS, including the native XML database, relational databases, Web Services, file systems, FTP, HTTP, etc. The cache adapter provides policy-driven read and write access to the data to ensure that the cached data is in-synch with the source data. With TigerLogic XDMS multi-schema engine and schema evolution, the cache adapter also handles dynamic data sources.

In Memory Cache
For additional performance, TigerLogic XDMS supports up to 64 GB of dedicated in-memory cache that is user configurable. The in-memory cache can be utilized to store data from the TigerLogic XDMS native XML database (both native and cached collections) in-memory for accelerated performance of queries.

Geospatial
High volume geospatial data in XML messages are becoming more prevalent in government and commercial applications such as those providing services to mobile wireless devices. TigerLogic XDMS provides an efficient and low cost method to handle this data by using commodity hardware, keeping data in an XML format and utilizing the in-memory cache. TigerLogic XDMS 3.0 includes a geospatial XQuery plug-in that employs GML to model geospatial data in XML. It is based on Open Geospatial Consortium Simple Features specification. Geospatial indexing is based on GiST and all supported GML constructs in the collection are automatically indexed.

Availability
Raining Data’s TigerLogic XDMS version 3.0 is currently available in beta. The future General Availability (GA) version will support Windows, Linux and Solaris platforms. To learn more about TigerLogic XDMS, go to http://www.rainingdata.com/products/tl/index.html.
