A Java ME Embedded Database
Object Oriented, Open Source from McObject
Perst Lite is McObject’s version of the Perst open source, object-oriented embedded database for mobile and embedded applications on the Java ME platform (also known as Java 2 Platform, Micro Edition or J2ME).
The Perst Lite Java ME database upholds Perst’s well-deserved reputation for simplicity of design and high performance, and also achieves a code size that is about 30% smaller than standard Perst, well within the resource constraints of most mobile devices.
Perst Lite retains nearly all the features that have been popular with users of the standard Perst open source Java database. These include B-tree, Patricia Trie, Bit index, T-Tree and R-Tree indexes as well as List, Relation, and Set collections, all protected by transactions supporting the ACID properties (Atomicity, Consistency, Isolation and Durability). Perst Lite also offers multithreaded access, data encryption and asynchronous replication.
