Specific task instructions
Scenario
You have been contracted as a software developer for an IT company to develop an application that calculates the cost of a travel package for one of their clients.
User requirements
• The user wants a piece of software for importing travel package items from a .csv file
• The comma delimited file contains data for three types of travel package items:
o Travel (flights, train, ferry, bus) o Accommodation (hotels, motels)
o Activities (visiting a museum, going on a tour, etc.)
• The method for calculating the cost of the package item is different for each type. The program must account for this and calculate the cost accurately, to ensure the cost of the entire package is correct.
• The start date and end date of a package are determined by the package items. The start of the earliest package item is the start of the package, the end of the latest package item is the end of the package.
• Once the total cost, start date, and end date have been calculated, the name of the package, its description, start date, end date, and total cost are written to: o A comma delimited file (.csv) using the naming convention timestamp packages.csv
? For example: 20200601093000-packages.csv
? For more information on getting a datetime in a specific string format, refer to the strftime method. o The console window.
• The IT company prides itself on providing high-quality software to customers and requires that unit tests be written for testing by: o Importing the data from the comma delimited values file and loading the data into a list of objects
o Checking the correctness of the values calculated for the start date, end date, and cost of each travel package.
Calculating Cost and Dates
Each package item should be responsible for calculating its cost. The package items have different logic for performing this calculation, as listed below.
Travel
Each form of travel has a flat cost, which will be found in the file.
Accommodation
The cost for accommodation is calculated by taking the number of nights stayed in that accommodation, multiplied by the daily rate. The daily rate is determined by the type of room.
Activity
Each activity has a flat cost, which will be found in the file. (research this more to see if there’s a better way to handle it)
Organisational development principles and practices
• The IT company uses an iterative approach to software development. Each stage must be checked as it is completed, with issues corrected in previous stages as necessary.
• All coding must comply with the coding standards as described in the PEP 8 -- Style Guide for Python Code.
• All modules, classes, functions, and methods should use type hints.
• All methods must have internal documentation as illustrated below in Figure 1 - C# Internal XML comments (example); further information is available at PEP 257 -- Docstring Conventions.
create an image of proper use of Python docstrings
Figure 1 - C# Internal XML comments (example)
• All tests must be documented using the Software testing documentation template (Software testing documentation.docx).
You must follow the listed Organisational development principles and practices in the appropriate stages of the project.
Download and unzip the resource folder (Dip_Nwk_Programming_AE_Pro_1of3_SR1.zip) for files referred to within the assessment.
Part 1: Review and clarify requirements
Meet with the client in a role play (10-15 minutes) to review and clarify the user requirements.
Your assessor will observe the role play and complete Observation Checklist 1.
Role play participants:
• Client – Your assessor will arrange for another person to participate as the client.
• Software Developer (this is you).
Ensure that you include the following in your role play:
1. Review and clarify the user requirements with the client, asking questions if necessary to ensure that you have correctly understood what is needed.

Part 2: Design the application
Using the information you have gathered through research and discussion with the client, create the project design documentation by including the following tasks in a wordprocessed report.
Task 1
Table 4 - Classes contains the information needed to plan and determine the application design. Create a class diagram of this information using software, MS Paint or even pen and paper. Ensure that the classes, relationships, methods and properties are captured in the diagram.
For more information on class diagrams read the web page UML Class Diagram Tutorial with Examples.
Table 2 - Classes

Task 2
The required application will be run on desktop computers, however the client would like to know what would be required if they wanted to convert it into an app.
Identify some systems (this may include IDEs, operating systems) and devices that have the potential to meet their future needs. You can use a table similar to below.
Systems Devices

Part 3: Develop the application
Task 1
Implement your application design to develop the application, ensuring that you follow the code and documentation conventions in the organisational requirements. You have been supplied with the payroll data file (employee-payroll-data.csv).
Note: Each row in the file denotes a single package item, however a package record for a single package can contain many package items.
1. Create a new Visual Studio Console Application using the following naming convention:
a. Project name: MyTravelPackageProject
2. Add a folder named Import to the root directory of the project and copy the provided file employee-payroll-data.csv into it (see Figure 2 – Import folder)
Figure 2 – Import folder
3.
Task 2
Task 3
Generate appropriate code metrics for your software to help with its maintenance.
Task 4
Ensure that your code follows the coding standards and is documented according to the Organisational development principles and practices listed in the scenario.
Part 4: Test the application
Develop and perform unit test cases to ensure that the application logic and syntax meet the user requirements and the re-use components work correctly within the project.
Task 1

Part 5: Evaluation
1. Before handing over your application to the client, write an evaluation report for the IT company in a word-processed document, using a style appropriate to the audience and purpose. Include the following in your report:
a. Evaluate how well you have met the user requirements and specifications.
This may be listed in a table, such as:
Specification Evaluation
[Specification as listed in the software specifications] [How well does your application meet this specification?]
b. Using examples from your code, identify different data types, operators and expressions that you used. Explain why you used them compared with other options.
Part 6: Perform handover
Meet with the client in a role play (10-15 minutes) to hand over the application.
Your assessor will observe the role play and complete Observation Checklist 2.
Role play participants:
• Client – arrange for another person to participate as the client.
• Software Developer (this is you).
Ensure that you include the following in your role play:
1. Present and demonstration the application to the client.
2. Obtain the client’s acceptance of the application.
