eXtremeDB Adds ODBC for Enhanced Connectivity, Developer Flexibility

McObject has added support for the Open Database Connectivity (ODBC) application programming interface (API) to its eXtremeDB™ in-memory embedded database system. The new feature greatly expands eXtremeDB’s ability to share data with systems ranging from mainframes to servers to desktop applications, and enables developers to create new eXtremeDB-based applications using an open and familiar database API.

eXtremeDB’s new ODBC support is included in eXtremeSQL 3.1, the new version of McObject’s SQL embedded database interface, on all platforms, including Linux, UNIX, real-time operating systems and Microsoft Windows. The ODBC driver is also available separately to provide Windows 32-bit applications with ODBC access to eXtremeDB databases residing on both Windows and non-Windows operating systems.

The ODBC interface works with all eXtremeDB editions (Standard, High Availability, Transaction Logging, and 64-bit) and with eXtremeDB Fusion, McObject’s hybrid on-disk/in-memory embedded database.

Perst Integrates with Apache Lucene for Full-Text Search in Embedded Databases

McObject announced that the newest release of the Perst™ open source, object-oriented pure Java embedded database system supports integration with the widely used open source, all-Java Apache Lucene information retrieval library, to provide highly efficient text indexing and searching within Perst databases.

In McObject’s new Perst for Java version 2.71, Perst functions encapsulate the Lucene indexing and searching APIs. Developers can designate fields within Perst object classes as full-text searchable, so that Lucene automatically adds these fields’ contents to its index, and provides the ability to search this indexed material using information retrieval library features such as support for single- and multi-term keywords, wildcards, proximity queries, phrase queries and relevance ranking. The integration also allows the Lucene index to be stored in Perst and protected by the database’s transactional capabilities.

Enhancements to the new Perst for Java embedded database also include multi-version concurrency control (MVCC) for “fine-grain locking,” enabling multiple simultaneous users to work more efficiently with Perst; and simplified management of database indexes. Read the full press release.

eXtremeDB High Availability (HA) Tests Compatible With MontaVista Carrier Grade Linux

eXtremeDB High Availability (HA) 3.1, the latest release of McObject’s in-memory embedded database system for real-time, high availability applications, has been tested as compatible with MontaVista Linux Carrier Grade Edition (CGE) 4.0.

eXtremeDB HA version 3.1 targets telecom and datacom embedded software with index functions for more efficient communications-related sorting and retrieval, and with an improved high availability sub-system. That makes it an ideal fit with MontaVista Software’s full-featured, deployment-proven Linux CGE 4.0, which adds advanced hard real-time capabilities, new and unique clustering services, and other features for building carrier grade telecom and datacom systems.

HPC Databases: The Data Ingest Challenge, HPCwire.
In this article, McObject CEO and Co-founder Steve Graves examines a bedeviling phenomenon encountered when preparing very large databases (VLDBs) for use in high performance applications: as the database grows larger, the “data ingest” rate slows down markedly. This article explores the technological reasons for this dwindling performance, and a possible solution in the use of database technology that stores and manages records entirely in memory.
