How large is the data you're working with? Airtable (expensive, with serious row limitations) and its open source alternatives (apparently great, but I've never used one) are basically what you're looking for. They allow you to create relationships pretty trivially. I largely use airtable for collaborative data entry work with 1-10 others, where I need to eventually throw the data into postgres. It works great. Though, it's hard to say where its limitations are until you're a bunch of hours into a project -- some features you'd expect to be easy can be extremely hard, or limited.
