SQL, known as “Structured Query Language,” plays a crucial role in organizing and manipulating data stored in relational databases.
Relational databases store information in the form of tables with rows and columns, allowing for organized structure and relationships between different sets of data. For example, a sales database might include tables for customers, products, and orders, each with their unique attributes and defined relationships.
SQL enables various operations on databases, such as insertion, updating, deletion, searching, and data retrieval.
One of the key advantages of SQL is its ability to integrate with various programming languages. This allows developers to incorporate SQL queries into their applications, creating efficient data processing solutions connected to leading database systems like Oracle or MS SQL Server.
