One of the most common ways to keep data memorized in computer systems is by relying on databases. Databases can be seen as large software containers that can hold lots of information in a structured and accessible way, in order to optimize how to store data and access their operations. Depending on the approach and model used, the way in which this is achieved can vary in terms of implementation. One of the most common ways is to use the relational model, which is based on relational algebra, for which data is a collected as a series of records that describe the relationships that exist among objects. SQL is a query language that is based on such concepts, and it is widely adopted in many database systems. This section will deal with these topics in depth by first explaining database management systems, relational databases, and SQL.
