The ChronoDB database project


Welcome to the home page of the ChronoDB database project.

On July 12, 2012, the ChronoDB database was renamed CrNiCKL because of a problem with the name. Development continues under the new name. The ChronoDB website will remain available for a while but without any activity.

The goal of this project is to produce a data manager for large sets of heterogeneous time series. ChronoDB runs on top of SQL or non-SQL databases. A JDBC version is in use since a few months. A NoSQL version is in preparation; it will probably use MongoDB, which supports "sharding". The project is sponsored by Hauser Olsson GmbH.
