Fourth-Generation Languages (4GLs) are high-level programming languages designed to be more user-friendly and efficient than earlier generations. They focus on reducing the complexity of coding by allowing users to specify what they want to achieve rather than how to achieve it. This makes them ideal for tasks like database management, report generation, and application development. 4GLs often include features like graphical user interfaces and built-in functions that simplify programming tasks. Examples of 4GLs include SQL for database queries and MATLAB for mathematical computations. These languages enable faster development and are commonly used in business and data analysis applications.
