J2ME Beats Flash Lite Again with Mobile Database

Posted by Charles | June 12, 2008 .

While we are waiting for Flash Lite 3 and dreaming about real Flash/Flex for mobile, J2ME charges forward. If you’re developing applications for Java-ME (J2ME)-based mobile device, and writing your own data management code, you should check out the Perst Lite open source, object-oriented embedded database from McObject.

Perst Lite is not completely new, it’s been featured in Terrence Barr’s Blog and has its own pages within the Java.Net Mobile & Embedded Community. It has also 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 that reduces stored data’s size by three to five times, on average. Coupled with the database system’s already-small footprint, this compression adds another reason for developers to choose Perst Lite for data management on smartphones, PDAs and other small-profile devices.
  • Improvements in Perst’s documentation. McObject has added a concise new38-page Tutorial and Introduction that guides users through the embedded database’s features and design principles, with code examples. Sections range from the basics – such as creating, opening and storing objects in a database – to advanced topics including schema evolution and database replication

Come on, Adobe, it’s time to reveal some details about Flex for mobile.
