Obsidian has built-in support for markdown, images, PDFs, canvas (via JSON Canvas which they developed and open sourced https://obsidian.md/canvas), and others.
For databases, you can add fields/properties both in the markdown frontmatter or in the text and query it via very popular plugins:

There are tons of community plugins that support all kind of stuff: tasks, kanban, LLM/Copilot, graph analysis of links, charts.
It can also be extended in JS, both writing your own plugins or via a few plugins that allow limited JS support.

Obsidian is actually quite good as a NoCode prototyping platform for personal apps :-)
E.g. CRUD:
- Use templates, via Templater: to define the content of your data
- Use links and tags to define relations and connections
- Use dataview or graphs for views
- There are even plugins to define buttons and the actions they perform, if you need commands
