In the last update (2023-01-31 - LifeOS to Notion), I decided to move most of my personal stuff to Notion, because I think the Notion's databases are very powerful. But I just figured out I used Notion just for this feature. So why not moving everything to an app focusing only on databases?
I experimented with Airtable. It's a good software, but I don't like its restrictions for its free tier. And I don't plan to pay for something I could do in Obsidian. Moreover, the data stored in Airtable was not mine and I could not back it up.
So I decided to use NocoDB instead. It's a bit less powerful, but I don't care because it's free and I don't want something very complex. I host it on a VM with Google Cloud using the free tier. The data is mine (even if it's hosted by Google) and is backed up to my own server every day.
I used Obsidian a lot for daily logs. To track things I have to do, to read, to keep logs of things I discovered, of people I met, etc...
All this stuff is now in NocoDB as it perfectly fits in a database system. One month ago, everything about me and all my logs were in Mindtopia. Now they're not.
The only things I keep here are things requiring big notes. So, weekly reviews, meeting reports, book reviews, etc... and pure PKM stuff such as my Zettelkasten system. This stuff fits perfectly in Obsidian as Obsidian was intended first to be a PKM system, even if it can do everything now thanks to plugins.
