An Object-Oriented Embedded Database for Android

With Perst, McObject offers an all-Java, open source, object-oriented embedded database for Android, the new mobile device platform backed by Google and the Open Handset Alliance.

Why use Perst in software for Android? Because Perst helps developers create small-footprint embedded Java applications that are fast, reliable, and cost-effective to develop and maintain. Perst can do this because it is:

Object-oriented. Perst stores data directly in Java objects, eliminating the translation required for storage in relational and object-relational databases. This boosts run-time performance.

Compact. Perst’s core consists of only five thousand lines of code. The small footprint imposes minimal demands on system resources.

Fast. In McObject’s TestIndex benchmark, Perst displays one of its strongest features: its significant performance advantage over Android database alternatives.

Reliable. Perst supports transactions with the ACID (Atomic, Consistent, Isolated and Durable) properties, and requires no end-user administration.

Rich in development tools. The Perst API is flexible and easy-to-use. The breadth of Perst’s specialized collection classes is unparalleled. These include a classic B-Tree implementation; R-tree indexes for spatial data representation; database containers optimized for memory-only access, and much more.

TestIndex is a package that demonstrates using Perst versus SQLite.
