ChronoDB is a data manager for generic time series.
The project has been renamed CrNiCKL (chronicle) and moved to http://crnickl.sourceforge.net.
ChronoDB is a data manager written in Java. It supports time series of any type. With its simple and powerful schema subsystem it takes charge of very large heterogeneous data sets.
