Description: Type mapping is the process of associating data types with their representations, allowing developers to define and manipulate data more effectively in their applications. In programming languages, type mapping refers to the ability to create new types based on existing ones, facilitating the creation of complex data structures and type validation at compile time. This not only improves code readability but also helps prevent common errors that can arise in dynamic programming. In data processing systems, type mapping is crucial for defining how data is transformed and processed, ensuring that operations are performed consistently and efficiently. In summary, type mapping is a fundamental tool in modern programming that enables developers to work with data more safely and structurally.
