BrickIt provides a portable Web-based registry that helps synthetic biologists to plan and organize the construction of Biobricks. Biobricks are standardized fragments of DNA (genes, switches, and more complex functional modules) that are openly and freely shared across the community of synthetic biologists (see biobricks.org. Brickit implements a database-backed Django Web server to coordinate and track the biobrick samples within a lab, institute, or local community.
Cubulus is an analytic engine and a slice and dice Web interface on top of a relational database (MySQL, PostgreSQL, SQLite, and MonetDB at the moment). It caches calculated cells and is able to parse basic MDX queries, with a maximum of two dimensions cross-join on rows and/or on columns. It includes hierarchical charts: the vertical boxes represent hierarchy "on rows", and horizontal boxes represent data sets "on columns" scaled to the "on rows" measure.
Custom is an E-Commerce system providing Ordering and Invoicing, Stock, Supplier, and Catalogue Management. Easily customisable, it is written in Python for use as CGI scripts (under Apache or any other Web server) with a simple example site and example database. Custom is intended as a modern replacement for Sage.
Elixir is a declarative layer on top of SQLAlchemy. It is a fairly thin wrapper that provides the ability to define model objects following the Active Record design pattern, and using a DSL syntax similar to that of the Ruby on Rails ActiveRecord system. It does not intend to replace SQLAlchemy's core features, but instead focuses on providing a simpler syntax for defining model objects when you do not need the full expressiveness of SQLAlchemy's manual mapper definitions.
Gaby is a small personal database manager using GTK+ and GNOME (if available) for its GUI. It was designed to provide straight-forward access to the types of databases a casual user would normally use, while keeping the ability to easily create databases for other needs. It was designed with extensibility in mind and relies heavily on plug-ins.
