Why use the Free Edition of JustOneDB?

The Free Edition allows you to quickly load and analyze up to one billion rows of data without design, complexity or huge amounts of hardware.

JustOneDB meets all of the following query demands within the same database.

Forensic - as supported by an indexed row store
