Data Dictionary
A data dictionary is a table that offers a detailed explanation of each database field.
This contains a description, an illustration, the field name, the data type, and the field size.
Data type denotes whether the data is text, a date (DD/MM/YYYY), or a currency, for instance.
The field name denotes the necessary information for that column.
The size of a field describes how much data will be entered.
There should be an example in the description along with a succinct description of that field.
A data dictionary example is shown below.
