eXtremeDB Fusion Combines Strengths of In-Memory & On-Disk Storage
McObject has released eXtremeDB Fusion™, which combines the strengths of on-disk and all-in-memory data management in a single embedded database system. This unparalleled flexibility enables developers to tailor data management in order to optimize applications for speed and persistence, while taking advantage of the most cost-effective and physical space-conserving approaches to data storage.

McObject’s eXtremeDB in-memory embedded database system delivers real-time performance and a tiny code footprint via its streamlined, all-in-memory design. But on-disk storage has advantages, too. Some developers prefer its guaranteed persistence, and byte-for-byte, disk storage can be cheaper than memory. Disk storage can also take less physical space.

eXtremeDB Fusion enables the developer to combine both database paradigms – in-memory and on-disk – in a single database instance. Specifying one set of data as transient (managed in memory), while choosing on-disk storage for other record types, requires a simple database schema declaration. Read McObject’s press release for more details.

New Benchmark Report Available

In Linux-based 160-Core Benchmark, eXtremeDB-64 Breaks IMDS boundaries
McObject’s 64-bit in-memory embedded database, eXtremeDB-64, pushes past known boundaries of in-memory database system (IMDS) scalability and performance in a new benchmark report based on tests with a 160-core Linux-based SGI Altix 4700 server. The results demonstrate eXtremeDB’s breakthrough responsiveness as well as its ability to grow to a size that is well within the range of the largest corporate on-disk databases. Findings include maximum performance of 87.78 million query transactions per second for a simple SELECT against a 1.17 Terabyte, 15.54 billion row database.

McObject’s benchmark report, In-Memory Database Systems (IMDSs): Pushing Past the Terabyte-Plus Boundary, tests eXtremeDB using its native interface as well as its SQL API, eXtremeSQL, and examines efficiency in provisioning the database. Among other results, the test found nearly linear scalability from a one processor up to 160 processor cores. Read a summary of benchmark results or download the paper.

Events

Embedded Systems Conference Silicon Valley
April 3 – 5, 2007 – San Jose, CA

McObject will exhibit in booth 422 in San Jose’s McEnery Convention Center at this foremost U.S. embedded systems event. ESC Silicon Valley brings together the world’s technology experts (faculty) from over 16 different countries. It provides in depth technical training for engineers relatively new to embedded design, all the way up to courses on cutting-edge technology applications and solutions. Topics include fundamental methodologies, processes, and techniques.

Stop by McObject’s booth to see the eXtremeDB in-memory embedded database (including eXtremeDB-Fusion), as well as Perst, our open source, object-oriented embedded database for Java and C# (and Perst Lite for J2ME). Contact McObject in advance to arrange a private meeting or demo.

Real-time and Embedded Computing Conference (RTECC)
April 24, 2007 – Boston, MA

Join us at the Marriott Boston Burlington for RTECC (link removed). McObject CEO Steve Graves is featured as speaker at this event, and McObject is an exhibitor.

The Real-time & Embedded Computing Conferences (RTECCs) are unique, one-day events showcasing the newest products and latest information from industry leaders. The events feature open-door technical sessions in conjunction with tabletop exhibits.

Feel free to contact McObject to arrange to meet at any of these events.
