Oracle database architecture is a multi-tiered structure that separates logical and physical data storage, allowing for efficient data management and retrieval. It comprises key components such as the Oracle Instance, which includes memory structures and background processes, and the Oracle Database, which stores the actual data in tablespaces and data files.

Data retrieval is the process of identifying and extracting relevant data from a database or data storage system for further processing or analysis. It involves using specific queries or search techniques to obtain precise information quickly and efficiently, often leveraging indexing and optimization strategies to enhance performance.

key components

An Oracle Instance is a combination of Oracle's memory structures and background processes that are used to manage database files. It is responsible for executing SQL statements and managing the data stored in the database, ensuring data integrity and concurrency control.

Memory structures are organizational frameworks within the brain that facilitate the encoding, storage, and retrieval of information, playing a crucial role in learning and cognitive processes. These structures encompass various types of memory, such as short-term and long-term memory, and are influenced by factors like attention, emotion, and repetition.

Background processes are tasks that run behind the scenes in a computer system, allowing the user to perform other tasks simultaneously without interruption. They are essential for maintaining system operations, handling tasks like updates, backups, and system monitoring without direct user interaction.

background processes

Oracle Database is a multi-model database management system produced and marketed by Oracle Corporation, known for its robust performance, scalability, and security features, making it a popular choice for enterprise-level applications. It supports SQL as well as NoSQL, providing flexibility in managing various types of data and workloads across different environments.
