I'm currently building a library of database schema that developers can use to design database schema faster. https://www.dbschemalibrary.com
I find myself spending days to design a database schema on every new project. The motivation behind this is that developers can use the library as reference or to copy paste from existing schemas. The hope is that those examples will lead to better design decisions in a shorter amount of time.
Would love to hear if this is something you'll find useful. Thanks!
