Mapper (software development)

In software development, a mapper is an object that exchanges data between two components . With the help of the mapper, this data exchange is possible without the two components knowing each other or the mapper.

The most common usage scenario for mappers is the data exchange between database and objects with the help of a data mapper . A design pattern related to the mapper is the mediator . In contrast to a mapper, however, this is known to the components communicating with one another.
