Question 2: Designing a train ticketing system requires a user graphical input interface, including the ticket departure time, price, number of trips, and the current number of remaining ticket displays. requirements: 1. Tickets need to display the following information: departure time, price, number of trips, current number of remaining tickets; 2. Display of the remaining number of votes must immediately reflect the change in the number of votes; 3. The user interface is easy to change and even change at runtime. This problem is designed using the MVC architecture (using the observer mechanism), where the user input interface and the display view are displayed independently.

If a software team is planning to develop a user interface on a smart phone, you must explain how difficult it is to implement user interfaces. Explain in detail the kind of activities are performed throughout the design of the interface when an item or categories in a list are presented.
Create a precise description of what the system described belown should and should not do along with any constraints on its operation and implementation. A parking deck system manages an entry/exit gate, which opens to let a vehicle (i.e., car) into or out of the deck and closes when the car has passed through. A driver must push a button to print a parking permit. When the driver takes the parking permit, the system raises the gate. The system lowers the gate after the vehicle has passed through. A permit id and time of entry is printed on the parking permit, and is also encoded on the permit’s bar code. When the vehicle leaves the parking deck, the driver inserts the parking permit into a bar code reader, which scans the bar code, and then transmits the bar code to the parking system. The parking system calculates a fee that is based on the number of hours that have elapsed since the vehicle entered the parking deck, and displays the fee to the operator and driver. The driver must…

ASSIGNMENT QUESTIONSConsider this scenario: Instead of the Green Dam Escort project, the Chinese government hires a huge international Namibian-based company to develop its compulsory internet browser program. The project is top-secret, and even the programmers aren't sure what it'll be used for. Meanwhile, you're working for Microsoft Inc. on a top-secret project in which code is divided into teams working on modules, and team members are kept in the dark regarding the whole application's functionality and purpose. You have a feeling it's a military effort, but you're not certain. Consider the possibilities below.Question 1: Virtue Theory [50 marks]You're concerned that the software module you're developing could be utilized by the government (or military) to track citizen internet usage. Such government invasion of privacy runs counter to your ideals and ethics, but it's just a hunch thus far. You tried to bring up this topic with your boss in an oblique way but were told that it was…
If a software team plans to develop a user interface for a smartphone, you have a responsibility to explain how difficult it is to put interfaces into action.When a list item or category is offered in the interface design, please provide a thorough description of the types of actions that are taken.
If you're working on a software team to create a smartphone user interface, you'll need to have a conversation about the best approach to take.Do you think it's tough to design user interfaces for computers? Be as specific as possible when describing the nature of the acts taken.While designing an interface, how do you know when an item has been shown or a list's categories have been shown?
Project 4: PyGame Assignment Overview This assignment focuses on the design, implementation and testing of PyGame programs to build games. Assignment Specifications Go to Invent with Python, Making Games with Python & PyGame and choose either Chapter 4: Slide Puzzle or Chapter 5: Simulate to complete. Assignment Note These chapters have quite a bit more information than the previous projects you have completed but as you have figured out by now, making a game in PyGame is a more lengthy process. You are allowed to use the chapter as a tutorial as to what you need to do to create the game. You are allowed to use the files in the chapter, rather than build the code from scratch. You must then change something in the code to make the game different to create your own remix. Assignment Deliverable You must turn in a file called proj04.py – this is your source code solution; be sure to include your names, the project number and comments describing your code.
You are asked to do a detailed design of part of a system using class diagram, modeling interactions and behaviour for a part of a library system. This part can be described as a use case: checkout an library item. In this use case, a librarian use the system to check out an item for a legitimate borrower. The system need to check the borrower’s record first and then update the library data, the borrower’s record etc. Design the graphic user interface for this use-case.

Draw Data Flow Diagram up to level-2 for the given scenario The client's ultimate objective is to have an online software system that gives information about the movies that the client sells to customers online. The system gives information about movies and actors/actresses. That is, the system should be accessed online. Each movie is identified by title and year of release. A movie has a genre (drama, comedy, etc.), a running time, and one director. A movie is made at a movie studio and may have multiple producers (people in charge of the movie production). A movie studio has a unique name and address, and may make one or more movies. Producers are identified by name and date of birth and produce one or more movies. Directors are also identified by name and date of birth and direct one or more movies. Assume that directors don’t act or produce movies. Actors are identified by name and date of birth, and may appear in one or more movies. An actor who appears in a movie, has a role.…
