Oracle Development is a suite of integrated tools and frameworks published by Oracle for building, deploying, and managing enterprise applications across cloud, on-premises, and hybrid environments. It addresses the need for scalable, secure, and high-performance application development by providing a cohesive stack built on Java EE, SQL, and modern web standards. Key components include Oracle JDeveloper, an integrated development environment for Java, SOA, and SQL; Oracle Application Development Framework (Oracle ADF), which accelerates enterprise application delivery using declarative development; Oracle Application Express (APEX), a low-code platform for web applications; Oracle REST Data Services (ORDS) for API exposure; SQL Developer and SQLcl for database development; and Oracle WebLogic Server for application deployment and management. This technology is for enterprise developers, database programmers, and application architects who require a robust, standards-based environment to design data-driven applications, integrate systems, and deliver scalable solutions using Oracle’s ecosystem.
