The tool assists in establishing items, such as variables, that will be contained within a program. Data Dictionaries contain the headings of Data Item, Data Type, Format, Number of Bytes for Storage, Size for Display, Description, Example and Validation. Data Item: The name of a particular field used in the program (PlayerID, First_Name) Data Type: The way the field will be recognised by the system (Integer, String, Real or Boolean) Format: The way data will be displayed by the system (DD/MM/YY or DD/MM/YYYY) Number of Bytes for Storage: Hard disk space required for saved data. Size for Display: Amount of RAM required to display the data Description: An outline of the type of data expected for the specific item. Example: A sample of expected data for the item Validation: Rules applied to data items to ensure correct data is entered.
