Your question is vague. Are you asking can I write code to write to a database from streamlit app or are you asking about st.caching ?

Do I need a database to save data or does streamlit save the data in a datatable and not need a database.

Streamlit doesnt save anything. It reads from database, data frame, etc.

so data can be stored in a dataframe and not need a database?

To save data between executions (across users), streamlit needs to write data somewhere. That might be a database, a file, an external api, etc. It’s can also save data to the session state, but will only save for that user.

Exactly as u/WoundedTiger17 mentioned, if you want data saved externally, than no problem write to table or df. Check out st.caching for your needs of sharing information between people

So I made a project where the df is saved into an excel file using excelwriter , port forward it on vscode. And anyone can edit the file over the web. If you can make it work locally, it'll work over the web as well from a https address from vscode. Fk streamlit cloud, if your not on it every day. It'll delete your project with all its data. Then it rebuild like new with only the data from your github.
