The Dawn and Rise of SQL and the Relational Database Industry

🌟Ted Codd's relational data model structured data into tables and championed data independence.

💡SQL (Sequel) was introduced as a query language for the first software implementing Codd's ideas.

🔥Oracle, founded in 1977, capitalized on the growing popularity of SQL and became a leading player in the relational database industry.

💻Ingres, founded in 1980, offered a competitive alternative to Oracle with its own data query language called QUEL.

🚀IBM joined the relational database market in the early 1980s with SQL/DS and DB2, validating the industry's potential.
