Distributed Object Database Systems

Most of these don't support general queries or server execution. Objects are only fetched by pointer traversal and all methods are executed on the client.

Gemstone has the opposite problem. Methods of persistent objects are only executed on the server, which wastes client resources and scales badly to large number of clients.

Software Component Models

These use manual static distribution of components and ad hoc support for "operating system" services such as persistence, security, etc.
