A computer programming term.
A 'data dictionary' describes the structure of data 'items' to be used within a software application.
Software development teams need this because everyone must use the same data formats when reading or writing data.
For example a 'data dictionary' for a team making an action game might have an entry like this:
NAME DATA TYPE
Hit Point, Number
The data dictionary item above is describing the format of a piece of data called 'monster'.
