15 Aug SQL (Structured Query Language)

SQL (pronounced like the word “sequel”) is a language used to access data in tables in a relational database management system (RDBMS). The language used a regular grammar and a set of reserved words to provide SQL developers the ability to create, read (“select”), update, append and delete data described within tables, and between tables linked by primary and foreign keys. The keys define the “relations” in “Relational”.
