Object database goes open source

Startup company db4objects this week is releasing its object database, db4o, under an open source format, with the product now available either under the GPL via open source or commercially as embeddable software.

Built for Java and .Net development, db4o enables storage of objects, according to the company. An example of an object could be a vitamin in a biotech application or a brake configuration in an automotive application, according to Christof Wittig, CEO of db4objects.

"Our database, basically it helps object-oriented developers using Java or .Net objects to simply store the objects," instead of having to disassemble and reassemble them for storage in a relational database, Wittig said.

db4objects adheres to a dual-licensing strategy, offering both commercial and open source options, like database vendor MySQL AB, Wittig noted.

To seed the market, users can download the database for free and use it for non-commercial purposes under the GPL, through which users must release source code for changes made to the software. The company believes previous object databases failed "because they were not penetrating the market because they were too high-priced," Wittig said.

The product's alternative commercial licensing, for embedding in units such as mobile devices, costs US$9 per device runtime. Companies developing and shipping proprietary products also can receive support and indemnification. Open source users also can purchase support.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
