For this week's content, we looked specifically at turning E-R Models and Diagrams into relational databases. If you've ever taken a course in database design, the relational database model is usually taught. Some of the most popular database systems follow the relational database model - MS SQL, MySQL, Oracle, MS Access, and so on. However, non-relational databases using NoSQL have started growing in popularity. Companies such as Facebook, Twitter, Netflix, and LinkedIn all use (or have used recently) NoSQL databases. So do a little research on the benefits and drawbacks of NoSQL databases. When should you use them? When would you not want to use them? Think outside the box and think like a systems analyst.
