“Public Sector Data Dictionary (DDSA) is defined as a standard description of a data element including the name of the data element, alias (another name of the data element), a brief description of the data, the size of the data element, the type of field and the rationale for the data element. It also sets data code standards for certain elements to be adopted by all Public Sector agencies.
