CRUD (Create, Read, Update, Delete) operations are the fundamental actions that can be performed on a database. These operations correspond directly to SQL (Structured Query Language) statements, which allow us to interact with a relational database. Let’s break down how each of these operations is mapped to SQL statements, with examples for clarity.

  1. Create (Insert Data)
    The "Create" operation in CRUD refers to adding new records into a table. The SQL statement used for this operation is the INSERT statement. This allows you to add one or more rows into a table by specifying the values for the respective columns.

    SQL Syntax:

     INSERT INTO table_name (column1, column2, column3, ...) VALUES (value1, value2, value3, ...); 

    Example:
    Suppose we have a table Employees with columns EmployeeID, Name, and Position. To insert a new employee into this table, ______ ____ ___ __________ ______ ______ _______ ________.
    ___ ________ ___ ___ _________.
    _________ ___ ____ ______ _______.
