Mapping is an operation that associates each element of a given set (the domain) with one or more elements of a second set (the range). In health informatics mapping is use frequently for associates some codes in a standard terminology to other codes in other standard. Interoperability is one of the high topics in Health Informatics. Sharing data and allow the interpretation of this information required the use of standard terminologies. Providing interoperability between different biomedical terminologies is a critical issue for efficient information sharing. Mapping terminologies is a way to facilitate consistent medical data exchange and achieve system interoperability and data standardization. One of the challenge for use medical terminologies, is the amount of different terminologies and the lack of automated methods simplifying the mapping process. Mapping is not an easy task, and there are non a single method to performed this mappings. Some Natural Language Processing techniques and other methods have been use for mapping some standards to another. The Unified Medical Language System (UMLS) metathesaurus have been use for mapping medical terminology standards. In the same way, some terminologies like SNOMED CT offers mappings to other terminologies. Automating the process of mapping as much as is possible can effectively reduce the cost and increase the efficiency and accuracy of this task over manual methods.

The term "mapping" is also used in some terminologies standards like SNOMED CT, for describe the use a code that was not post-coordinated.
