I find myself having many RDBMS-type information that needs to follow me around and be available to multiple distributed apps. I need the strict referential integrity and type-checking that typically are found in RDBMS.
I can set up my own servers or use hosted RDBMS for the data but it seems that Solid might also offer an interesting avenue. These are smallish datastores (<10MB).
I’ve tried some web-based versions such as Airtable and Caspio, but I want to own my own data vs. just store it on their servers.
