Understanding Different Types of SQL Languages

 In the world of databases, different SQL languages serve specific purposes. Let's break down three important ones:

A. Data Definition Language (DDL)

Data Definition Language is all about defining and managing database structures. This includes creating, altering, and dropping database objects like tables and indices. Essentially, DDL gives us the power to set up the framework of our database.

B. Interactive Data Manipulation Language (DML)

Interactive Data Manipulation Language lets us work directly with the data within our database. We use DML to insert new data, delete existing records, or update information already stored. It's the hands-on tool for managing the content of our database.

C. Embedded Data Manipulation Language (EDML)

Embedded Data Manipulation Language allows SQL statements to be used within other programming languages. This means we can integrate database operations seamlessly into our applications written in languages like Java or Python. EDML is like SQL's backstage pass, making it play nicely with other code.

Each of these SQL languages plays a crucial role in building and interacting with databases, making them powerful tools for developers and database administrators alike.
