Notion's data model is incredible, actually. You can embed almost anything into it, and make it work across your knowledge base.Databases work like spreadsheets, and you can embed pages inside them, too. In fact, every row is a potential page, if you want.While I prefer Obsidian for my technical (public and private) knowledge bases, life organization, and specific help pages I create for relatives live in Notion, and it works really well. Being able to script and formulate things allows great flexibility.What I'm not very comfortable yet is "ejecting" from Notion, since the data model is so convoluted, what they give you as a package is not very convenient, yet.Evernote had the best mechanism, giving you an XML file and an official XSLT to read/verify/transform what they give you. However, Evernote feels very underpowered when you start to use formulae and automation across your database.

the data model is banal. just a tree with limited "type" strings for the special things. it's literally no different than any other file format. and they make it as difficult to export as all the other companies

Odoo is powerful but a hideous ui and ux, which bloats the platform.I feel like if Odoo foxed this it could be incredibly useful
