Coding frameworks have moved development away from database development and lean heavily on ORM's. It is a double edged sword. All the code ends up in the same place, it is easier to maintain, and functionally it is the same. When that translates to database code it often causes performance and wasteful practices. One of the core optimizations of database design is proper indexing. ORM's can help you do this, but does not do it for you. Profiling tools can suggest the exact indexes you need based on how you are using the database. You can think of indexes as a bookmark for combinations of columns that speed up data lookup.
