SEATTLE, USA: Birdstep Technology has announced the upcoming release of version 9.0 of its Raima Database Manager Embedded also known as RDM Embedded.

Advertisment

This is the latest release from the Raima Database Management Family providing exciting new capabilities and functionality for embedded systems application developers, and topping the list is a micro HTTP server.

General availability of this new version of the popular embedded database is targeted for mid December 2008.

The new micro HTTP server is a fully HTTP 1.1 (RFC2616) compliant Web server designed for threaded and thread-less operating systems and applications. The server can host RAM and disk resident content as well as the pre-integrated RDM Embedded data.

The server is engineered for small footprint and resource constraint devices. In addition it is fully extendable, allowing developers to add virtually unlimited functionality to the server. One possible use for this is an application to monitor time interval data points which can dynamically adjust parameters.

Take for example a power consumption application that monitors the power usage of a shop floor. When the power consumption level reaches a certain threshold, the application makes adjustments to the machinery parameters, also stored in the database engine, to bring the consumption level back within the acceptable range. If the user wants to override the application by adjusting the power consumption threshold they can easily do so via a remote Web application, possibly running on a handheld device.

Another new feature in RDM Embedded 9.0 is circular tables which allow developers to define a maximum row count. When the limit is reached, new rows will reuse the previously allocated space. It uses the First in First out (FIFO) concept meaning the oldest record is replaced by the new record. This is useful for applications that contain event logs or statistics where rather than letting the table grow infinitely large or managing the size manually, the size of the table can be handled automatically by the database engine.
