Embedded Object Oriented Database System for PHP

I would like to announce embedded object oriented database for languages with dynamic type checking: DyBASE. Currently APIs for Python, Ruby and PHP are available. DyBASE is easy to use and provide high performance. It is intended to be used in applications which needs to deal with persistent data in more sophisticated way than load/store object tree provided by standard serialization mechanism. Although DyBASE is very simple, it provides fault tolerant support (ACID transactions) and concurrent access to the database. DyBASE is free and open source software distributed under MIT license. You can find more information about it and download this product at www.garret.ru/~knizhnik/dybase.html
