Though we may not recognize them in our everyday activities, databases are everywhere. For instance, they are fundamental to online banking profiles, airline reservation systems, medical records, and employment records. This course provides a general overview of databases, introducing you to database history, modern database systems, the different models used to design a database, and Structured Query Language (SQL), a pervasive language used to access and manipulate databases. Many of the principles of database systems are applicable to other areas of computer science, especially operating systems. Database systems are one of the core computer science topics since many other subjects in the discipline have been derived from this area.
