XMLPipeDB

XMLPipeDB is a fantastic suite of Java-based tools that is completely free and open source. The software is designed to make the process of automatically building relational databases from an XML schema (XSD) as easy and painless as possible. One of the standout features of this software is its ability to manage, query, import, and export data from XML sources without requiring much in the way of manual processing. This means that users can quickly and easily get started with their database projects, without having to spend time wrestling with the data.

While XMLPipeDB can be used for a wide range of applications, its primary focus is on the management of biological data from different sources. This is particularly useful in creating Gene Databases for GenMAPP (Gene Map Annotator and Pathway Profiler), a software tool for viewing and analyzing DNA microarray along with genomic and proteomic data on biological pathways.

Overall, XMLPipeDB is a powerful solution for anyone looking to manage large datasets of XML data. Whether you are a scientist, researcher, or programmer, this software provides an intuitive and easy-to-use interface for building, managing, and querying databases without the need for extensive manual processing of the data. Best of all, it's completely free and open source, making it accessible to anyone who needs it.
