How do you design an efficient, relational database? 

A poorly designed database is more of a liability than an asset, and it’s quite easy to get your design wrong if you don’t learn SQL programming the right way. Your database might work just fine at the start, but as data volumes grow so does the complexity of the database management system that your entire business relies on. 

Over time, this complexity limits the scalability of your database, and worse yet, makes it difficult to ensure data security.
