The Structured Query Language (SQL) is the ANSI (American National Standards Institute) standard for communication with relational databases. Originally developed at IBM labs in the early 1970s by Donald D. Charmberlin and Raymond F. Boyce, SQL is based upon the principles of relational algebra, set theory and tuple relational calculus. It is split up into a data definition language and a data manipulation language. The former specifies the data types and fields in which tables are stored in memory, in addition to subsequent relations to other tables. The ladder is what enables SQL statements to be used to update and insert data into a database, or retrieve data from a database.
The ubiquity of SQL in professional practice guarantees that as a computer science, or engineering student — you will encounter projects requiring knowledge of SQL.
