On the spot courier services chapter 4

14/10/2021 Client: muhammad11 Deadline: 2 Day

Running Case Study: On The Spot Courier Services

In the final project you will continue the work you did on the midterm project in your use of the running case study. You will continue to design the system for the case study - focusing on aspects of the class diagrams and database design. Perform the activities below based upon which semester this is (or instructor designates). Upload your completed project in Microsoft Word format in the dropbox.

Formatting
This should be written as a cohesive business document with all of the necessary diagrams, tables, etc. There are few specific requirements:

Title Page is required
Use 11pt or 12pt font for your body text
Use builtin styles of Word such as headings, lists, captions, etc.
All diagrams/tables should have captions
Here are tips to creating an excellent project:

1. Please do not have the questions from the assignment in the document. The questions are simply the requirements for the report that you are writing. The headings and narrative you add to the document will be enough to explain the section and why it's in the document.
2. Please add narratives to your sections, subsections, figure explanations, etc. For example, don't just list actors. You need to explain to the reader what this section is about, why these actors were chosen, and perhaps a brief description of the actors. For example, your section may start off like this "This section/subsection is a result of our use-case analysis where we have identified the users (actors) for the proposed system..." (You use own wording and style of course).
3. I expect to see a table of contents in these documents. if you are using the headings from Word, then you can automatically generate the table of contents.
4. This is not just a final project; you need to treat this like a work assignment you might have on the job. This is a good time to hone your writing and document formatting skills.

Fall:

Case Study: On the Spot Courier Services

1. Using information from chapter 8 and previous information from the running case study paragraphs over the previous chapters, list at least five domain model classes that form the core functionality of the system.

2. List at least five tables corresponding to the domain model classes above. Include the following information for each of the tables: primary key, foreign keys to other tables, and other attributes that you think is needed to characterize the class. Also include whether or not the table is in third normal form or not - and why.

3. Develop a multilayer sequence diagram for the use case you fully developed in the midterm project that includes the domain classes and data access layers. This should be similar to the example shown in Figure 13-18, 13-19, and 13-20.

4. Develop a package diagram that includes all the problem domain classes and organized around the major subsystems. Use Figures 13-25 as an examples of the diagram that is organized around the View, Domain, and Data Access layers.

5. In designing a deployment architecture for the system, what are at least five design considerations you would take to implement a scalable, highly available, and secure run time environment?

6. Present a set of storyboards for the user interface of your system

Running Case Study

Michael Dimond

System Analysist

Problem Description

Founder of On The Spot Courier Services, Bill Wiley discovered he had minor issues with his business. He was having trouble getting business. He would advertise to local businesses that needed same day delivery. After that didn’t work he knew he needed to change things. Like build his own website where companies could place shipments online, get software to manage customer accounts, and a database to keep track of inventory.

System Capabilities

· Be able to have customers place orders online as an alternative to over the phone.

· Easily manage inventory

· Create customer accounts for easier tracking.

· Have delivery drivers be able to scan in packages upon pickup and store that info in warehouse database.

Business Benefits

· Make ordering pickups and shipments easier for customers.

· Easier way to track shipments and know what is in the warehouse at all times to prevent loss of package.

· Make tracking packages easy for customers so they will want to continue doing business with you.

The stakeholders for On the Spot would be Bill Wiley, the customers, warehouse staff, and delivery personal. The customer should be actively involved in the system definition because they will be placing the orders. As the business grows Human Resources (payroll, accountant) would also be involved.

If I were commissioned to build the system I would determine the requirements by:

I would first interview the users and stakeholders to understand the business function and need. Then review inputs, outputs, and procedures external to the organization and existing business documents. I would then observe and document the business process to better understand what occurs in the courier business functions. Using the information obtained from the business functions I would then research vender solutions to avoid common mistakes, save time and money. Lastly, I would collect user comments and suggestions to ensure the system is accurate and functioning.

Some questions needed answered are as follows:

· What are the business operation and process?

· How are the operations performed?

– how is it done? –what steps are taken? – can they be done another way?

· What information is needed to perform the operations?

–what information is used? – what inputs are used? –what output is produced?

-Use Case actors:

· Customer

· Employee (Driver)

· Bill

-Use Cases:

· Requesting a package pickup

· Picking up a package

· Generate Bill

· Print Label

Use Case Diagram

Access Controls

a. Bill (Owner): Should be given access to all financial records, as well as payroll, customer info, and shipping info.

b. Customers: A user control for the customer is customerID so only they have access to their account.

c. Warehouse workers: warehouse workers do not require access to any controls, therefore have no access controls.

d. Delivery Driver: security locks and safeguards must be placed on handheld scanners to protect shipping info in case of loss or theft.

e. Suppliers: Should be given limited access to view weather the shipment has arrived or not.

All data should be encrypted, especially on handheld devices or anything that leaves the main office or warehouse. If any of the encryptions were hacked, then all customer and supplier info could be at risk of being stolen. Especially billing and payment info.

Domain Model Classes

· Payment
