Oracle Corporation was founded in 1977 by Larry Ellison, Bob Miner, and Ed Oates. Initially named Software Development Laboratories (SDL), it later became Oracle Systems Corporation and eventually Oracle Corporation. The company's first product was Oracle V2, a relational database management system (RDBMS), which was released in 1979.

Key Milestones:

• 1979: Oracle V2, the first commercial SQL-based RDBMS, is released.
• 1983: Oracle Version 3 is released, rewritten in C programming language.
• 1980s: Oracle becomes a leading database vendor, competing with IBM and other major players.
• 1990s: Oracle introduces PL/SQL, a procedural extension to SQL, enhancing database programmability.
• 2000s: Oracle acquires numerous companies, including PeopleSoft and Siebel, expanding its product portfolio.
• Present: Oracle continues to be a dominant force in the database market, offering a wide range of database solutions and cloud services.

Evolution of Oracle Programming:

• Early Oracle programming primarily involved writing SQL queries and stored procedures.
• The introduction of PL/SQL allowed developers to create more complex and sophisticated database applications.
• Over time, Oracle has added support for various programming languages, including Java, enabling developers to build integrated solutions.
• Today, Oracle programming encompasses a wide range of technologies and techniques, including cloud-based database development and big data analytics.
