Description: A logical operator is a fundamental component in programming and data manipulation that performs operations on one or more boolean values, which can be true or false. These operators allow for the combination or modification of logical conditions, facilitating decision-making in algorithms and database queries. The most common logical operators include AND, OR, and NOT. The AND operator returns true only if both conditions are true, while OR returns true if at least one of the conditions is true. On the other hand, NOT inverts the value of a condition, turning true into false and vice versa. The correct use of these operators is essential for building complex and efficient logical expressions, allowing developers to filter and manipulate data effectively. Furthermore, understanding them is crucial for designing systems that require conditional logic, such as software applications and database management systems, where decisions are based on multiple criteria.
