Final answer:
Data mapping, also known as code mapping, is the process of matching data elements or codes from one set to their equivalents in another set, which is essential in fields like computer programming, data management, and information technology.
Step-by-step explanation:
The process described in the question is known as data mapping or code mapping. This process is crucial in various fields, including computer programming, data management, and information technology. Essentially, data mapping involves the identification and linking of each element from one dataset to an element in another dataset. This can involve connecting field names, identifiers, or actual data values from one database to those in another, ensuring that the data is correctly transferred and transformed between systems. In coding, this could mean equating one set of codes to a new set, ensuring that the program understands and correctly processes the information.
Data mapping is often used during data migration projects, where data from an old system needs to be transferred to a new one, or when integrating data from various sources. It is a critical step to ensure consistency, accuracy, and the useful flow of data across systems, applications, or formats.
