In Margal & Word (2012), when describing the role of data within enterprise systems, the authors make specific reference to the term "organizational data," which is a term commonly used within the SAP world (e.g., during ERP configuration).

The below image provides an example of the format (words are nonsense) you must adhere to when submitting your review questions. It is important to include only 'answers' in your submission (i.e., do not put into your submission the text of the question you are answering - just include your answer), as this hinders plagiarism checking. (Grading penalty for including questions is 20% of maximum grade). But you must number your answers.

Please also include proper references to material you have used within your submission (as you are obliged to do).

Use a consistent 12 point font.
