ORACLE:

Welcome to My Learning Hub!

This is the place where I share everything I learn, from tech insights to the latest advancements in the world of databases. Today, we’re diving into Oracle Database—an essential tool for managing data efficiently and securely. Let’s explore how it works and the languages that make communication with Oracle databases seamless.

🔹 ORACLE: Relational Database Management System (RDBMS) 🔹

Oracle is a powerful Relational Database Management Software (RDBMS) that helps create, maintain, and organize databases in the form of tables. These tables store data in an easily manageable and structured way.

What Can Oracle Do?

• Data Storage:
  Oracle allows users to store large volumes of data efficiently and securely.

• Data Retrieval & Manipulation:
  It provides tools to retrieve and manipulate data stored in the database using simple and powerful query commands.

💬 Communicating with Oracle: Two Key Languages

To interact with an Oracle database, we use two main languages: SQL and PL/SQL.

🗣️ SQL (Structured Query Language)

• What is SQL?
  SQL is a query language used to communicate with a database. It allows users to perform tasks like retrieving, updating, and deleting data.

• Key Features:

  • Query-Based: SQL queries are sent to the database server to retrieve or modify data.
  • Unified Language: SQL is the common language used to interact with any Relational Database Management System (RDBMS).
  • No Programming Required: SQL doesn’t require programming skills to use; it’s designed to be simple and intuitive.
  • 4th Generation Language (4GL): SQL is a high-level language, making it easy to write and read.

💻 PL/SQL (Procedural Language/SQL)

• What is PL/SQL?
  PL/SQL is an extension of SQL, adding procedural programming capabilities. Unlike SQL, it supports loops, conditional statements, and variable declarations, allowing more complex operations.

• Key Features:

  • Programming Language: PL/SQL is a full-fledged programming language that allows for advanced logic and processing.
  • Set of Statements: It includes a set of statements that can be executed together, making it a powerful tool for managing complex database operations.
