A short comparison of ObjectStore, Versant, Poet, and Objectivity mostly focusing on the evaluation criteria.

An object-based database management system optimized for user interaction instead of transaction processing. It includes a database browser providing secure access to its server across the Internet. C++ binding for several flavours of UNIX. [Source code freely available but not on website.]

Internet accessible object-oriented database that allows inherently secure remote access to (legacy) data from fixed and wireless devices. Also provides on-line schema evolution and access audit mechanisms.

Main memory database for embedded devices with no need for secondary storage persistency. Provides ACID transactions. Schema compiler generates object-oriented-like interface using C as target language. Available for Win32/Windows CE, QNX, VxWorks, Linux and others.

ODMG 3.0 compliant DBMS (including OQL) with manipulatable classes, templates and triggers. Supports multi-database objects. C++ and Java bindings. [Free for educational purposes]

Fully distributed ODBMS using a fat client model. The client side contains an adaptation layer to enable language independence and metaobjects to represent different aspects of transactions and caching. Currently only C++ bindings. [Open Source]

Single-node DBMS with SQL-like query language, arrays, computed attributes and a C++ API. [Open Source]

Simple, fast object-oriented database engine optimised for real-time and embedded applications. C++ bindings under MS Windows.

This report provides a critical review and technology assessment of Object-Oriented Database Management Systems and evaluates seven major ODBMS.

ODBMS compliant with the ODMG 3.0 standard. It's available as Just Edition (for small applications) and Enterprise Edition with extra components for replication, load-balancing and fault-tolerance. Supports Windows and Linux. Free Just version available on Web site.

The Z Object Publishing Environment consists of an object database (ZODB) and application server (ZServer) written in Python.

is an LGPL extension to the Zope DB that provides indexing and querying.
