The history of Oracle development is closely tied to the evolution of Oracle Corporation and its flagship database product, Oracle Database. Founded in 1977, Oracle initially focused on developing relational database management systems (RDBMS). Over the years, Oracle Database has evolved significantly, incorporating new features, technologies, and programming languages.

Early Years:

• In the early days, Oracle developers primarily used SQL to interact with the database.
• As the database evolved, Oracle introduced PL/SQL, a procedural extension to SQL, which allowed developers to write more complex and efficient database applications.

Mid-1990s to 2000s:

• The introduction of Java and the rise of web applications led to the development of Java-based tools and frameworks for Oracle development.
• Oracle Application Server (OAS) became a popular platform for deploying Java-based applications that interacted with Oracle databases.

Present Day:

• Today, Oracle development encompasses a wide range of technologies, including SQL, PL/SQL, Java, APEX, and cloud-based services.
• Oracle Cloud Infrastructure (OCI) provides a platform for developing and deploying Oracle-based applications in the cloud.

Key Milestones:

• 1977: Oracle Corporation founded.
• Early 1980s: Introduction of SQL.
• Late 1980s: Introduction of PL/SQL.
• Mid-1990s: Adoption of Java.
• 2000s: Rise of web applications and Oracle Application Server.
• Present: Cloud-based Oracle development with OCI.
