The Data Dictionary is a list of all the fields being used in the ERP along with the length of the field, whether it is numeric or alpha, decimals, and should also contain the valid values associated with the field.
It should also tell you what table the field is stored in. This is extremely valuable if you are an analyst as you need to know where to pull the data as well as what the values and meanings are. This is a rather simplistic answer.
