Affiliates is an affiliate management system for clubs, communities, schools, and associations. It allows you to set up and maintain a database and provides a graphical interface, a mailing and label printing tool, an email tool, an archive and initialization tool, import and export to CSV files, membership and record cards, support for JPEG images, templates for forms and documents, and networking support.
ODB is a compiler-based object-relational mapping (ORM) system for C++. It allows you to persist C++ objects to a relational database without having to deal with tables, columns, or SQL and without manually writing any mapping code. The C++ code that performs the conversion between persistent classes and their database representation is automatically generated by the ODB compiler. The ODB compiler is a real C++ compiler except that instead of producing assembly or machine code, it generates portable C++, which can in turn be compiled by any C++ compiler. ODB is not a framework. It does not dictate how you should write your application. Rather, it is designed to fit into your style and architecture by only handling C++ object persistence and not interfering with any other functionality.
eLabFTW is an electronic laboratory notebook system. Once installed on a server, every member of a lab can write up their experiments, upload files, manage a database of products (antibodies, chemicals, siRNA, papers, or whatever you want). It was created with usability and security in mind, is very easy to use, and has a long list of features specific to research life.
Midao JDBC simplifies development with Java JDBC. It is flexible, customizable, and simple/intuitive to use, and provides a lot of functionality: transactions, working with metadata, type handling, profiling, input/output processing/converting, pooled datasource libraries support, cached/lazy query execution, named parameters, multiple vendor support out of the box, custom exception handling, and overrides. With a single jar, it supports both JDBC 3.0 (Java 5) and JDBC 4.0 (Java 6). Midao JDBC is well tested. Not only does it have around 700 unit and functional tests, but it's also tested with the latest drivers of Derby, MySQL (MariaDB), PostgreSQL, Microsoft SQL, and Oracle. Midao is a data-centric project. Its goal is to shield Java developer from nuances of vendor implementation and standard boilerplate code. Midao JDBC is the first library released under it.
PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension.
