Where is Apple Remote Desktop data saved?

I am using an iMac running High Sierra and Apple Remote Desktop 3.9.

I am using ARD to collect iMac information like serial number and related stuff. Also, I have created lists with specific names and put specific computers in each group.

I use ARD for inventory purposes and related information. It has taken a lot of time to create the individual groups and collect the information.

Another user in iMore forums, said it is saved as an SQL database. I tried to use Finder to locate it or search it but there isn’t anything that comes up.

Where does the data get saved in this iMac? I do need to preserve this information and keep everything intact.
