There are a number of advantages of using Data Dictionary in computer system analysis and design. The advantages are: consistency, clarity; reusability; completeness; increase in sharing and integration; and ease of use for the developer. To elaborate on one important advantage, completeness, using Data Dictionary for the advantage of completeness helps the data programmer to know when data is clear, complete, and well defined. It does so by informing as to what completeness is defined as in any instance in question and by detailing the steps that are necessary to take to achieve completeness.
