Keep the full history of your data for time travel analysis, audits, to correct human or application errors...

SirixDB takes care of keeping storage space to a minimum while supporting the reconstruction of any revision in linear time.

Furthermore, it allows time travel queries such that you're able to analyze the history of your data efficiently to predict the future or for audits.

Not enough? What about correcting any human or application errors or to compare any revision of your XML or JSON documents efficiently?
