All of the following are true about Modular Programming except:
A. Modules should contain Go-To statements
B. Paying attention to the interfaces is important
C. Modules should be highly cohesive
D. It facilitates breaking the programming into logical, manageable portions

Question 2:

A military information system on a base overseas tracks personnel on the base. Each military member is tracked by ID#, name, rank, and address. Each military member belongs to an organization on the base which has an organizational name, located in a building on the base and has a primary function (e.g. Communications Squadron). Each of these  organizations is also commanded by one of the military members . In tracking command sponsorship each military member may have one or more dependents. Each dependent has an ID#, name, age, and sex. Each organization on the base is involved working issues or projects which may be of interest to the base commander. Each organization also belongs to a command which has a location and a unique numerical designation. The Organization's projects are tracked by a serial number and an origination date. The information system you are designing will also track descriptions of the projects and their close-out dates.

Build an entity relationship model for the above scenario. Show all attributes and indicate all of your key attributes in red.

Question 3:

Draw a DFD (Context and Level 1) for placing an order based on the E-R diagram shown here.

Some recommended major processes are:

(1) Enter new order
(2) Read customer master
(3) Read item record
(4) Create item order record
(5) Add order record


Question 4:

Select the best answer for each of the multiple choice questions below about the Structure Chart shown here.

344_er diagram1.png

How many times does the top module call each subordinate module?

Three times

The Set Up Claimant Record and Calculate Claim Amount and Provide Claim Summary Modules once and the Update Account Module many times until the Last Claim Flag is returned C. As many times as it takes to process all the claims (Until Last Claim Flag is Returned)

Which module actually contains the logic to call the Update Account Module?

Set Up Claimant Record

Calculate Claim Amount and Provide Claim Summary

Process Medical Claims

In what order does the executive module call the subordinate modules?

Update Account, Set Up Claimant Record, Calculate Claim Amount and Provide Claim Summary

Set Up Claimant Record, Update Account, Calculate Claim Amount and Provide Claim Summary

Set Up Claimant Record, Calculate Claim Amount and Provide Claim Summary, Update Account

Calculate Claim Amount and Provide Claim Summary, Update Account, Set Up Claimant Record

What tool would not be useful in preparing a Module Specification for a programmer to code the Update Account Module
Structured English
Flow Chart
Data Flow Diagram
Pseudocode

Question 5:

In this class, we've stressed the importance of various system analysis and design tools and techniques. By now you should have a "toolbox" full of useful design and analysis tools. List the tools in your toolbox and then write one short paragraph on how you can/will apply them in your careers, lives, etc.
