Why Would we use a Private blockchain instead of a database ?

[zebox6]

Hello guys,


I was looking for informations about private blockchains. Some say it's crap, some say it can save money compared to a database for a company in some cases.
I'm not a developer so my vision is on the business-side. Databases are convinient and easy to implement in most systems. My question is why and in which cases a private blockchain would be better and how to implement it ?
Do you have some information about how would it save money ?


Thanks in advance if someone responds
