Piggydb is a flexible and scalable knowledge building platform that supports a heuristic or bottom-up approach to discover new concepts or ideas based on your input. You can begin with using it as a flexible outliner, diary or notebook, and as your database grows, Piggydb helps you to shape or elaborate your own knowledge. Piggydb is a Web application provided as a self-contained package that contains a Web server and database engine.
With Piggydb, you can create highly structured content by connecting knowledge fragments to each other to build a network structure, which is more flexible and expressive than a tree structure. Fragments can also be classified using hierarchical tags.
Features

 - Text Fragments (with wiki formatting) / File Fragments
 - Organizing your fragments in a flexible network structure

 - Document View: browsing your organized content in printer-friendly format
 - Full text search
 - No installation needed: Just unzip downloaded archive and run the file

    I have used piggydb before and never had any problems. However, I just downloaded the latest version and cannot get it to run. I am running Windows 7 and have both the 86 and 64 version of java. Could the program by trying to run the wrong java?

    It's a very nice and polished piece of software. I've started using it as a research journal: i've set up a server and access the app through my favorite browser and operating system. Keep up the good work!
