My data - base (not a DB) is org-mode, org-roam managed, org-attached files. Actually org-roam use SQLite under the wood but I can say I do not use it directly.

My data - base (not a DB) is org-mode, org-roam managed, org-attached files. Actually org-roam use SQLite under the wood but I can say I do not use it directly...
