The ObjectBase Project could have been called Object Oriented DataseBase but we found at least two contradictions in that. This is not object oriented, it is just objects. This is not a database because we do not persist data, we persist objects.
The goal of this project is to develop a modular SQL engine (JDBC driver) that can be grafted onto any raw database (such as a large flat ASCII file) through a database module API. Writing database drivers is much easier that writing a whole RDBMS.
LAMP eGovernment Database Project offers state and local governments a free open source, web-enabled system for use in developing public information sites. You can also use this system for government-to-government systems as well.
This project tries to define a new grammar to be used for database access. It should be easier to learn, understand and use than SQL, be more consistent, and contain significantly less rules. It does not try to be an extension or subset of SQL.

Not a search engine but navigation routes within a research domain.
The Centre d'Informations (CI) aim is to articulate and display whatever type of knowledge available on a given field (see screenshots examples for various fields).
The software is built as a network of information articulated using concepts (figure). The website should not be understood as a conventional search engine but as different ways to navigate within this knowledge (information and concept) network.
Each information is thoroughly formalized; the aim is not exhaustivity or...
