Janice has been given the responsibility of creating and managing the data dictionary for the laboratory IS that is being implemented. There are a number of existing ISs that have their own data dictionaries. The data from the laboratory IS will be part of a clinical data repository. She decided that she needs to start from scratch to make the data dictionary the best it can be. She is reviewing the data dictionaries from the other ISs used at the healthcare facility but she does not always use the same terminology and format that are used in the other ISs.
