Explore Oracle database fundamentals, including memory structures, background processes, and physical and logical storage, and learn how SQL interacts with tables, rows, columns, and table spaces.
Learn the foundations of SQL for relational databases, including SELECT, INSERT, UPDATE, DELETE, and CREATE, to manage and interact with data, and prepare for exploring Oracle database architecture.
Explore Oracle architecture by distinguishing the in-memory instance from the on-disk database, covering SGA, PGA, background processes, data files, control file, and redo log for durable storage.
Explore how the Oracle instance uses memory, especially the SGA, with the buffer cache, shared pool, redo log buffer, and optional large pool and java pool to boost performance.
Explore the Oracle instance's system global area, including the database buffer cache, shared pool, redo log buffer, and large pool and Java pool, and their role in performance and recovery.
Explore the Oracle instance memory processes and background workers, including the database writer, log writer, checkpoint, smon, process monitor, and archiver, and their roles in recovery and performance.
Learn how Oracle background processes, including the database writer, LGWR, checkpoint, SMON, process monitor, and archiver, manage memory, redo logs, and recovery operations.
Explore how Oracle uses physical and logical storage to manage data, including data files, control files, and redo logs, and how table spaces, segments, extents, and data blocks organize storage.
connect client applications to the oracle database via the listener, which routes requests to the correct instance, while odbc and jdbc enable integration with power bi and tableau.
Learn how ODBC and JDBC connect Oracle databases to external tools, using DSN drivers on Windows and Java-based web or enterprise applications, enabling Power BI, Tableau, and more.
Review Oracle database concepts and SQL fundamentals, then outline the Oracle architecture, memory structures, storage layers, and data flow from listener to applications using ODBC and JDBC.
Course Description
This course contains the use of artificial intelligence.
This beginner-friendly Oracle Database Architecture course is designed to help you understand how the Oracle Architecture works. This course focuses entirely on concepts and architecture, not coding or installations.
Instead of diving into SQL syntax or setup, you’ll build a strong mental model of Oracle Database fundamentals. You’ll learn how Oracle databases are structured, how data flows through the system, and how key components like memory, processes, tablespaces, and transactions work together behind the scenes.
Each lesson breaks down complex ideas into easy-to-follow visuals, making this course ideal for absolute beginners, career switchers, students, or anyone returning to Oracle after a period of absence. The whiteboard format keeps things clear, practical, and approachable, helping you understand why Oracle works the way it does.
This is the first course you need to understand how Oracle works in the backend. It focuses on building a clear, beginner-friendly foundation by explaining Oracle database concepts at a high level, without coding or complex setup. Using simple, visual explanations, you’ll learn how Oracle is structured, how data flows through the system, and how core components like memory, processes, and storage work together. This course helps you develop the mental model needed to confidently discuss Oracle architecture.
By the end of the course, you’ll be able to visualize Oracle architecture,
This course provides a fast and friendly foundation for understanding the Oracle architecture. Are you ready to get started?
