Most apps and products have a database. Instead of starting from scratch why not start with a template. Rowy database templates just give you a ready-to-use database template for Firebase collections - You can get started with not just the data fields but also ready to use cloud functions for data changes on those columns.
Get started quickly, and then continue to extend and update as you want for your use case.
Some sample database templates:
Countries Table - Includes columns of country names, flags, currency, capital, continent, and country code. Get started by cloning this collection and start building your Firebase app easily.
