I noticed there is a section in the Axis demo (configs/sim/axis/db_demo/)  to load the tool database from an external source such as SQlite. Does anyone have an experience with this? It could be a useful options to track tool usage and other metrics.

Not sure how well known it is, or how much development time it has gotten. Looks like it's been around since 2021.

It is a relatively recent addition. I have no experience with it but here is the documentation (which you may have already found):
linuxcnc.org/docs/devel/html/tooldatabase/tooldatabase.html

For example, a db_program database application can maintain the operating hours for all tools by tracking each load/unload of a tool. A machine could then have three 6 mm endmills in pockets 111, 112, and 113 with the database application programmed to assign tool number 110 to the 6 mm endmill with the fewest operating hours. Then, when a LinuxCNC program requests tool 110, the database would specify the appropriate pocket based on tool usage history.

I've been reading through it, and I got some code working to interface with the system and load tools from a SQlite database.

I think this is a  useful feature. Here's what I've put together so far, it's still a work in progress and I want to make it work with the database structure from here
