Think youre right, i think thats a gap that most developers dont admit because you can do a lot even with basic skills. I mean, i can build an app from scratch, up a database, configure it, define the relations, and all those everyday things
But man, dont ask me to optimize the databases, to debug big data, to migrate huge dbs with no pain (is that possible?), to apply rules to increase the response time, to reduce relational complexibility, i must recognize that im not the best person to do it :/
