CPS $310$ Phase $2$ Data Flow Diagrams, Data Dictionary, Process

Specification

Due Date: Friday, July $19$th$,11$:$55$PM $($PDF format, via Canvas$)$

Overview

This phase involves several tasks:

$1.$ Revise your document from Phase $1$ based on comments you received.

$2.$ Develop Data Flow Diagrams.

$3.$ Create a Data Dictionary.

$4.$ Complete Process Specifications.

Your Task

$1.$ Based on comments left by the professor for your Phase $1$ grade, revise your document and

make any other changes you deem necessary. It is especially important to revise the context$-$

level data flow diagram should you have comments from Phase $1.$

$2.$ Building off of your context level data flow diagram, create a Diagram $0$ as we have discussed in

class. If possible, create at least one process that can be further decomposed into a child

diagram. If you are unable to create a child diagram, include an explanation of why.

$3.$ For the data dictionary, create data flow descriptions for each flow in your set of data flow

diagrams, craft the needed data structures for your system, and data store descriptions for each

data store in your set of data flow diagrams.

a$.$ For the data flow descriptions, include a uniquely descriptive name, a description, the

source, the destination, the name of the associated data structure and any needed

comments.

b$.$ For the data store descriptions, include the data store id$,$ a name, alias, description and

name of associated data structure.

$4.$ For each process identified in your set of data flow diagrams, create a process specification.

Include the number, name, description, input and output data flows, reference to the associated

structured decision, and any comments or unresolved issues.

a$.$ Attempt to include at least one of each technique of structured decision: structured

English, decision table, decision tree. If you are unable to use one of the techniques,

explain why.

Graduate Students

For the graduate students in the class, please expand your data dictionary to include five data element

descriptions. Each description should include the name of the element, any aliases, a short description,

whether the element is base or derived, the type of data it contains, validation criteria, default value if

appropriate, and any needed comments. This is required for graduate students but undergraduate

students may include this for extra credit.

Deliverables

You are required to turn in a PDF document containing the revised portions of Phase $1,$ additional data

flow diagrams as the system allows, a data dictionary, and process specifications for each process

identified in the data flow diagrams. Only one submission per team is needed on Isidore. Ensure your

document has a title page with the phase number and all names of the group members. A separate peer

review will also need to be submitted through Canvas
