If you're developing applications for Java-ME (J2ME)-based mobile devices, and writing your own data management code, you should check out the Perst Lite open source, object-oriented embedded database from McObject (www.mcobject.com)..

Perst Lite was featured recently in Terrence Barr's Blog on the Java.Net Mobile & Embedded Community, and has been featured in articles like this one  and this one  on Embedded.com. Since coding a database management system from scratch is no easy job, it makes sense to look at Perst Lite before you "re-invent the wheel" of database capabilities for your next Java ME software project.

You can freely download  complete Perst and Perst Lite package. Complete documentation is available here (scroll down).

Early this week, McObject announced an upgrade  of the Perst and Perst Lite embedded database systems. Improvements in Perst Lite include the following:

• Powerful on-the-fly compression in Perst Lite 3.0 that reduces stored data’s size by three to five times, on average, reducing the database system’s already-small footprint;

• Improvements in Perst’s documentation, with a concise new 38-page Tutorial and Introduction that guides users through the embedded database’s features and design principles, with sections ranging from the basics – such as creating, opening and storing objects in a database – to advanced topics including schema evolution and database replication.

Feel free to send me an e-mail if you have any questions!
