Ask HN: Ideas to manage DB correctly

Hi HN,

I'm currently working on a project that requires working with data and do some processing. I've been reading about software architecture and I think that the best design is use a separated database server. My current plan is to use a Python Flask app to create a REST API that saves the data to a few Google Spreadsheet. Is this a good solution?

Another question is how do I test this? I was thinking in create some tests to try to write some data using the Flask app and "assert" that the response codes are correct.

Is this a good approach in general?

Summary: I'm using a Python Flask app to access the data in Google Spreadsheets. Good? Bad? Opinions?

Thanks :)
