When software gets sufficiently complex it needs a database management system to store, structure, and query its records. In this episode we talk about what a database is, the models behind the most common kinds of databases, and some of the different use cases for each. We concentrate on relational databases, but we also discuss some so-called "NoSQL" databases including document-oriented databases, key-value stores, and graph databases. Along the way we learn a little history and about some of the concepts underlying relational databases including SQL and relational algebra.
