Microsoft SQL for beginners : Perform CRUD Operations

Understanding SQL: The Foundation of Relational Databases

SQL, which stands for Structured Query Language, is the standard language used for managing and interacting with relational databases. Developed to simplify database operations, SQL allows you to efficiently access, manipulate, and analyze data. SQL achieved standardization in 1986 by the American National Standards Institute (ANSI) and in 1987 by the International Organization for Standardization (ISO), solidifying its position as a cornerstone of data management.

What can you do with SQL? The possibilities are vast! With SQL, you can:

• Retrieve Data: Execute queries to extract specific information from your database.
• Insert Data: Add new records into your tables.
• Update Data: Modify existing records within your database.
• Delete Data: Remove unwanted records from your tables.
• Create Databases: Establish new, organized storage spaces for your data.
• Create Tables: Design the structure of your data storage within a database.
• Create Stored Procedures: Develop reusable blocks of SQL code for common tasks.
• Create Views: Define virtual tables based on queries for simplified data access.
• Manage Permissions: Control access to tables, procedures, and views for security.

SQL Standards and Extensions

While SQL is a standardized language (ANSI/ISO), it's important to note that different database systems may offer their own proprietary extensions. However, all compliant systems support core commands like SELECT, UPDATE, DELETE, INSERT, and WHERE in a consistent manner.
