An Open source JDBC driver written in Pure Java (Type 4), which communicates using the PostgreSQL native network protocol. The PostgreSQL JDBC Driver allows Java programs to connect to a PostgreSQL database using standard, database-independent Java code. pgJDBC is an open source JDBC driver written in Pure Java (Type 4), and communicates in the PostgreSQL native network protocol. Because of this, the driver is platform-independent; once compiled, the driver can be used on any system. pgJDBC allows Java programs to connect to a PostgreSQL database using standard, database-independent Java code. pgJDBC provides a reasonably complete implementation of the JDBC specification in addition to some PostgreSQL-specific extensions. The current development driver supports eleven server versions and three java environments.

OpenRefine is a powerful Java-based tool designed to work with messy data and improve it. With OpenRefine you can load data, understand it, clean it up, transform it, reconcile it, and augment it with web services and external data. It allows you to do this all from a web browser and in the convenience and privacy of your own computer. OpenRefine keeps all data securely in your computer by running a small server on it, using your web browser to interact with it. When you're ready, then that is the only time the data will be shared outside of your computer. OpenRefine is available in over 15 languages, is cross-platform and part of the Code for Science & Society.

BeanDB intends to implement relational algebra with JavaBeans as domains and various storage engines as backends; including direct storage into a file system and RDBMS. This provides an alternative to object-relational mappings for Java developers.

Big Sack is a Java persistence mechanism that allows storage of key value pairs following the popular Big Data paradigms. Its a very simple and straightforward way to bridge the gap between in-memory data structures and long-term storage. It has the convenience of Java SDK TreeMap and TreeSet classes and is used the same easy way, but it includes rollback through undo logging to checkpoint data so it does not wind up in an unknown state regardless of failures. Data storage in the exabyte range is possible using filesystem and/or memory-mapped IO. Three levels of configurable write-through caching at different granularities ensure performance.

Bodega is a distributed objects database framework for AJAX, RIA, REST, SOA, and Web Services.
