BBoxDB is a scalable, highly available, and distributed data store for multi-dimensional big data. The software supports operations like multi-dimensional range queries and spatial joins. In addition, data streams are supported.

Date range picker, two-pane calendar with custom rendering and multiple selection. The tDatepicker more than 35 pretty options and many methods help you change date, getDate, update when you need.
