What is SQL?

SQL stands for Structured Query Language. It's the standard language used to access and manipulate databases. SQL gained widespread adoption when it became a standard of the American National Standards Institute (ANSI) in 1986 and the International Organization for Standardization (ISO) in 1987.

What Can SQL Do?

SQL is a powerful tool with a wide range of capabilities:

• Execute Queries: Run commands against your database.
• Retrieve Data: Fetch information from your database tables.
• Insert Records: Add new data to your database.
• Update Records: Modify existing data in your database.
• Delete Records: Remove data from your database.
• Create Databases: Establish new database instances.
• Create Tables: Design and build new tables to store data.
• Create Stored Procedures: Develop reusable blocks of SQL code.
• Create Views: Define virtual tables based on queries.
• Set Permissions: Control access to tables, procedures, and views.

RDBMS: The Foundation of Oracle and Beyond

RDBMS stands for Relational Database Management System. It's the core technology behind SQL and forms the basis for virtually all modern database systems, including:

• MS SQL Server
• IBM DB2
• Oracle
• MySQL
• Microsoft Access

How RDBMS Works:

Data within an RDBMS is organized into database objects called tables. A table is a structured collection of related data, composed of columns (representing data fields) and rows (representing individual records). Understanding RDBMS is essential for any aspiring Oracle DBA.
