Requirements:-

A) Documentation

Data dictionary:-

Complete at least THREE (3) key data flow descriptions (Logical data dictionaries)

Data element descriptions (Physical data dictionaries, at least 1 of the key data entities)

Process Descriptions:-

A brief description for each of the key processes (top level processes in level 0 DFD) written in plain English

Write at least ONE lower level process description in structured English

B) Provide a structured analysis of the functional requirements of the system presented as a set of logical data flow diagrams and prepare a data model represented as an entity-relationship diagram for the current system.

The set of data flow diagrams should include:

Identify key events and complete an event table and DFD Fragments

Context Diagram: This must be for the whole Printing Incorporated ebook Publishing and Sales Management System. You need to show relevant external agents together with data flows between the system and the external agents.

A set of levelled data flow diagrams which includes:

1) Level 0 DFD which includes all top-level processes,

2) At least 1 top level process from this Level 0 DFD decomposed to level 1 DFD.

You will be assessed on your application of data flow diagrams according to the following criteria:

DFD syntax

DFD data conservation (also commonly known as balancing or data consistency in some textbooks)

Quality of names o Logical, not physical

Quality of modelling is more important than quantity

Consistency - not only should each view (data flow, process, data store) be accurate and readable, but also the views must be consistent with each other, so the whole analysis makes sense.

C) An Entity Relationship Diagram (ERD): It should be a high-level data model (many to many relationship is acceptable in this unit).
