Coding Task Question

Coding: HTML/CSS, Javascript, MySQL, EJS 

Task 1

In this task we will come up with initial design for a software application that you will build in this semester. 

We will not be writing any code in this task, but only looking at some initial design ideas and high level architecture.

Description: 

A partner of your company has requested to build a software application that will predict the rate of the fuel based on the following criteria:

  • Client Location (in-state or out-of-state)
  • Client history (existing customer with previous purchase or new)
  • Gallons requested
  • Company profit margin (%)

Software must include following components:

  • Login (Allow Client to register if not a client yet)
  • Client Registration (Initially only username and Password) - Client Profile Management (after client registers they should login first to complete profile)
  • Fuel Quote Form with Pricing module (Once user enters all required information pricing module calculates the rate provides total cost)
  • Fuel Quote History

Answer these questions:

  1. Discuss your initial thoughts in details on how you will design this application?
  2. Discuss what development methodology you will use and why?
  3. Provide high level design / architecture of your solution that you are proposing?

Task 2

In this task you will build the front end for the web application that you designed in task 1. 

Remember, we are only building front end in this task.

Description: 

Same as task 1.

Additional Details:

Front end must include following components:

  • Login (Allow Client to register if not a client yet)
  • Client Registration (Initially only username and Password) - Client Profile Management (After client registers they should login first to complete the profile). Following fields will be on Profile page / form:
  • Full Name (50 characters, required)
  • Address 1 (100 characters, required)
  • Address 2 (100 characters, optional)
  • City (100 characters, required)
  • State (Drop Down, selection required) DB will store 2 character state code
  • Zipcode (9 characters, at least 5 character code required)
  • Fuel Quote Form with following fields: (We are not building pricing module yet)
  • Gallons Requested (numeric, required)
  • Delivery Address (Non-editable, comes from client profile)
  • Delivery Date (Calender, date picker)
  • Suggested Price / gallon (numeric non-editable, price will be calculated by Pricing Module - we are not building pricing module yet) - Total Amount Due (numeric non-editable, calculated (gallons * price))
  • Fuel Quote History
  • Tabular display of all client quotes in the past. All fields from Fuel Quote are displayed.
  • You should have validations in place for required fields, field types, and field lengths.

Answer these questions:

Discuss if your design and development methodology has changed since task

1 and why? 

List what front end technologies you are using and why.

Provide screen shots of your front end, each page

Task 3

In this task you will build the back end for the web application that you designed in task 1. 

Remember, we are only building back end in this task.

Description: 

Same as task 1.

Additional Details:

Back end must include following components/modules:

  • Login module
  • Client Profile Management module
  • Fuel Quote module, includes list of quote history for a client.
  • Pricing module. Only create a class. You will implement this in last task.

Important deliverables:

  • You should have validations in place for required fields, field types, and field lengths in backend code as well.
  • All backend code should be covered by unit tests. Code coverage should be grater than 80%.
  • Research how to run the code coverage reports. Each IDE has plugins to generate reports. Here are few pointers. https://stackify.com/codecoverage-tools/
  • All front end should be connected to back end. Form data should be populated from backend. Backend should receive data from front end, validate, and prepare to persist to DB. - WE ARE NOT IMPLEMENTING DB yet. For this task you can hard code the values.

Answer these questions:

List what backend technologies you are using and why? 

Provide code coverage report. 

Task 4 

In this task you will create the database and connect it to your web application.

Description: 

Same as task 1.

Additional Details:

Database must include following tables: - UserCredentials (ID & password), password should be encrypted.

  • ClientInformation
  • FuelQuote
  • Any additional tables you feel, like States.

Important deliverables:

  • You should have validations in place for required fields, field types, and field lengths.
  • Backend should retrieve data from DB and display it to front end. - Form data should be populated from backend. Backend should receive data from front end, validate, and persist to DB.
  • Any new code added should be covered by unit tests. Keep code coverage above 80%.

Answer these questions:

Provide SQL statements to create database.

Rerun the code coverage report and provide it.  

Task 5

In this task you will create the pricing module for Fuel Quote Form and put together the complete project that you have built so far.

Description:

Same as task 1.

Additional Details:

Create a pricing module that should calculate the price per gallon based on this formula.

Suggested Price = Current Price + Margin

Where,

Current price per gallon = $1.50 (this is the price what distributor gets from refinery and it varies based upon crude price. But we are keeping it constant for simplicity)

Margin =  Current Price * (Location Factor - Rate History Factor +

Gallons Requested Factor + Company Profit Factor)

Consider these factors:

Location Factor = 2% for Texas, 4% for out of state.

Rate History Factor = 1% if client requested fuel before, 0% if no history (you can query fuel quote table to check if there are any rows for the client)

Gallons Requested Factor = 2% if more than 1000 Gallons, 3% if less

Company Profit Factor = 10% always

Example:

1500 gallons requested, in state, does have history (i.e. quote history data exist in DB for this client)

Margin => (.02 - .01 + .02 + .1) * 1.50 = .195

Suggested Price/gallon => 1.50 + .195 = $1.695

Total Amount Due => 1500 * 1.695 = $2542.50

Additional Validations:

  • Make suggested price and total amount fields in your Quote form read-only, i.e. user cannot enter these values.
  • Create another button on Quote Form before Submit, call it "Get

Quote".

  • After user enters all other fields in the form other than Suggested

Price and Total Amount, allow user to click on "Get Quote", i.e. Get Quote and Submit Quote buttons should be disabled if there are no values entered in the form. 

  • When user clicks on "Get Quote" button make a call to Pricing Module and populate the suggested price and total.
  • Display Suggested Price and Total Amount once you get the values from pricing module.
  • Make sure you do not lose any form values when you make a call to

Pricing module.

  • You can use AJAX call to achieve this i.e. partial form submission. 
  • Then user clicks on Submit Quote and you save the quote.

Deliverables:

Rerun the code coverage report. Code coverage must be above 80%. Demo prior to project due date.
