What is the Difference Between Oracle and SQL

Difference Between Oracle and SQL

Difference Between Oracle and SQL: Oracle and SQL databases are utilized for effective data management and organization. This blog examines how Oracle and SQL Server differ from one another, emphasizing their features, capabilities, and applications. After reading this, you will have good knowledge that will enable you to choose the database system that best suits your requirements.

When it comes to working with databases, we often come across the two most discussed terms, Oracle and SQL. Both of them have unique features; however, understanding the differences between them can be a bit confusing, especially for those who are new to Database Management systems (DBMS).

Both serve different purposes and have distinct features. The key difference between SQL and Oracle is that SQL is used to interact with Databases. In contrast, Oracle is a relational database management system (RDBMS) that uses SQL to query and manage data.

In this blog, we will explore the differences between Oracle and SQL, which will help you understand their features, uses, and how they work together in databases.

What is the Difference between Oracle and SQL

There is more to comprehending Oracle and SQL differences than just technical aspects. It involves assessing their performance, compatibility, licensing, and degree of alignment with the objectives of your company. The key differences between Oracle and SQL are discussed below.

The main aspects of difference between Oracle and SQL are:

Definition

SQL (structured query language) is a programming language used to manage and manipulate relational databases. SQL is used to perform tasks such as querying, updating, and managing data within a database. It is not a database but a language used to interact with databases.

On the other hand, Oracle Database supports SQL as the primary query language. Oracle is a relational database management system (RDBMS). It is used to store, manage, and retrieve data.

Oracle uses PL/SQL, whereas SQL Server uses T-SQL, which is an important difference between Oracle and SQL.

Functions

SQL is used to write queries and commands. It performs tasks like inserting, updating, and deleting data.

Oracle is used to manage databases. Oracle database is a platform that uses SQL to perform operations on data.

Architecture and Components

SQL works with tables, rows, and columns.

Some major Commands used are mentioned below:

DDL (Data Definition Language): For creating and managing database schema (e.g., CREATE, ALTER, DROP).
DML (Data Manipulation Language): For managing data within tables (e.g., SELECT, INSERT, UPDATE, DELETE).
DCL (Data Control Language): For controlling access (e.g., GRANT, REVOKE).
TCL (Transaction Control Language): For managing transactions (e.g., COMMIT, ROLLBACK).

Oracle includes

Oracle RAC (Real Application Clusters): This is for high availability and load balancing across multiple servers.
ASM (Automatic Storage Management): For efficient storage management.
Data Guard: Disaster recovery and high-availability solutions.
Advanced Analytics: Tools for data mining and predictive analytics.
In-Memory Database: This is for faster processing of analytical queries.

Performance

SQL performance depends on the underlying database engine. Some features of SQL are indexing for faster queries and query execution plans.

Oracle provides partitioning, In-Memory options, and optimizer hints.

Security

SQL supports encryption and provides access through GRANT and REVOKE. Oracle uses Transparent Data Encryption (TDE), Fine-grained access control (FGAC), and advanced auditing options.

Cost

SQL is a language, while open-source databases like MySQL are free. However, Oracle is known for its high cost. Oracle provides high-cost with full features. This is the main difference between SQL, MySQL, and Oracle.

What does SQL Stand for?

SQL (structured query language) is a programming language used to manipulate and manage relational databases. It performs tasks such as updating, querying, inserting, and deleting data. This language is used to create the structure of a relational database and manipulate the content stored in it.

SQL is not a database but is a language supported by various RDBMS, including Oracle and MySQL. SQL is a powerful tool for managing databases and performing a wide range of operations on them.

Key Features of SQL

SQL is a declarative language that focuses on “what” to do rather than “how” to do it.
It is a highly versatile language.
SQL is user-friendly and easy to learn.

Functions of SQL

Data Definition
Used to define the structure of the database with commands like CREATE.
Data Manipulation
Used to insert, update, and delete the database using commands like INSERT, UPDATE, and DELETE.
Data Control
Uses commands like GRANT and REVOKE to manage user privileges.
Data querying
Used to retrieve data from tables using commands like SELECT.

Difference Between SQL and PL/SQL

PL/SQL (Procedural Language/SQL) is an extension of SQL used in Oracle databases.

The main differences between SQL and PL/SQL are

Definition

SQL is a language used to query data.

PL/SQL is a procedural language and is an extension of SQL. It focuses on “HOW TO DO”.

Execution

SQL executes one statement at a time, whereas PL/SQL executes a block of statements at a time.

Purpose

The main purpose of SQL is data retrieval and manipulation, and PL/SQL is programming logic and procedures.

Support

SQL is supported by most RDBMS, but PL/SQL is exclusive to Oracle Databases.

What is the Function of MySQL?

Oracle Corporation develops MySQL. MySQL is an open-source relational database management system (RDBMS) that’s used to store and manage data. MySQL uses SQL to create and manage databases. It stores data in tables of rows and columns. MySQL is used in applications like Facebook, Netflix, Uber and Shopify. It’s a popular choice for developers because of its reliability, performance, scalability, and ease of use.

Difference between Oracle and MySQL

The main differences between Oracle and MYSQL are:

Licensing

MySQL is an open source and free edition that is available with additional features.

Oracle is commercial, and a fee is required for additional features.

Performance

MySQL provides good performance for difficult operations and query optimization.

Oracle possesses advanced performance features and performs complex transactions.

Security

MySQL provides basic security features such as user authentication and access control.

Oracle provides advanced security features such as encryption and auditing.

Cost

MySQL community edition is free of cost, whereas the enterprise edition is paid. Oracle requires high costs for licensing and support.

Data Models

MySQL supports basic JSON handling and Oracle supports documents, XML, and graph data.

Scalability

MySQL is good for smaller-scale databases, whereas Oracle performs large-scale operations.

Null values

MySQL allows null values, while Oracle does not.

Oracle Database Online

Oracle provides many online platforms for managing databases. Some of them are:

Oracle learning subscription: It provides tutorials and certifications for database professionals.
Oracle Cloud Infrastructure: It offers secure and scalable cloud database solutions.
Autonomous Database: It allows users to create self-managing databases.
Free Tier Access: It allows new users to use Oracle features at no cost.

Conclusion (Difference Between Oracle and SQL)

Oracle, SQL, PL/SQL, and MySQL are all necessary components of database management systems (DBMS). It is very necessary for someone who is using databases to understand the difference between Oracle and SQL. Oracle is a powerful RDBMS, whereas SQL is a language used to query and manage databases.

PL/SQL enhances Oracle’s functionality by allowing users to write complex programs with conditions and loops. MySQL is an open-source RDBMS that is simple, flexible, and cost-effective. One can easily achieve efficiency and success in database management systems by choosing the right tools.
