Ander, I'm not really sure how seeing the UI makes it easier to provide examples of working DB design, but this is our existing front end: https://apps.library.albany.edu/dbfinder/ Some of the limitations of the current front end are because the backend DB is only partially relational with duplicated information throughout. There are a number of exceptions and logical manipulation of query results hardcoded into the app to deal with the deficiencies of the DB. It works, but barely. The new DB will be hosted in MariaDB, and if designed well, should make the app code clean and efficient. From the smidgen of DBA instruction I do have, I know 80% of any DB project should be in the design. As I said though, there are multiple many-to-many relationships and we aren't sure how to design that well. Most subjects have sub-topics and most subjects (and subtopics) have one specialist, but could have more. Specialists have multiple subjects and sub-topics, of course. Resources can fall into multiple subjects and sub-topics and may be ranked for their usefulness within a subject or sub-topic. Resources may also have multiple types (i.e. images, video, dictionaries, newspapers, etc.), and multiple resources will have the same type. Hope that is what you are looking for.
