I feel that a lot of new users struggle with bubble, not just because there is a learning curve to the bubble platform itself, but because most are non-coders and do not have a background in database design.
Personally, once I began to understand database design a bit more, it had profound impacts on how I was able to build using bubble, especially when it came to ease of manipulating data.
I also feel, that a lot of new users forget about Google…that powerful search engine that can point you in the direction of the information you seek, mostly because it seems like our answers should be coming from the bubble forum. In my experience, I have learned a lot about bubble on the forum, but I’ve learned things that have improved my abilities off the forum for things like user experience design and database design, two crucial components to building a successful app.
One of the best resources I have come across using google when searching for database design models is a website called Vertabelo.
The site has lots of database models available with explanations for each data type involved, the different data fields in each and the relationships between them.
For anybody in need of guidance on database design, they should check it out.
They have different professional database designers who post articles that are basically how to tutorials. Here is a link to one designer who has database models that I find helpful for retail sales models.
If you can’t find what you are looking for…remember google. Just type in the search bar what type of database design you are in need of followed by “vertabelo” and they just might have an article on it.
