Description

Oracle Database is a powerful relational database management system that offers a broad range of features for data storage, retrieval, and manipulation. It uses Structured Query Language (SQL) for database interactions and provides advanced tools for performance tuning, backup and recovery, and high availability. Oracle Database also supports programming in PL/SQL, a procedural language extension to SQL. Advanced features include real-time data integration with Oracle GoldenGate and comprehensive management with Oracle Enterprise Manager. Mastery of these skills enables the design and implementation of complex database architectures, ensuring efficient and reliable data management.

Expected Behaviors

Fundamental Awareness
At this level, individuals have a basic understanding of Oracle Database concepts and architecture. They are familiar with SQL basics and data modeling concepts. They understand what relational database management systems are and how they work. However, their knowledge is mostly theoretical, and they may not have much practical experience.
Novice
Novices can install Oracle Database and perform basic SQL queries. They understand Oracle Database security features and can create and manage tables. They also know basic backup and recovery procedures. Their skills are still developing, and they may need guidance when dealing with more complex tasks.
Intermediate
Intermediate users are proficient in advanced SQL queries and can design and implement Oracle Database schemas.
