The owner of Lunara restaurant decided to build an application for managing the food orders placed by their customers. The proposed application will allow customers to register their details like name, location, phone number and email in the customer file, and receive a registration confirmation letter. Also it will allow them to make orders by browsing the food menu and select their food and add them to the orders file. In addition, it will allow them to complete the payment process either by visa or cash and finally they will receive the receipt. The employees also will be able to add new items to the menu, edit the…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…Task: Maldives Disaster Management wants to build a software to track vessels in danger at sea.They want to track the vessels location. If an emergency occurs the vessel should contact theconcerned authorities automatically. They should provide the location to the nearest coastguard unit available and the location of the vessel should be constantly communicated to thedepartment in an emergency.For this application you are to write:1. A detailed user specification. Must clearly identify the functional requirements, nonfunctional requirements and user requirement2. A brief design plan of how the system should work. 3. A discussion on the methodologies and the methodology you will choose to build thissoftware application. You must discuss the relative merits and drawbacks of thefollowing. a. Plan driven development methodologyb. Agile development methodology Introduction ReferencingWord count: 3000 words

Draw a UML class diagram describing an object-oriented system using the list of requirements below. Each user can own many games. Games have many copies in the system. Games have many achievements and collectibles. Each achievement can be accomplished by many players. There are two types of items in the system: seasonal item and collectible item. Users can obtain many items. There are three types of user interactions: post, reply and (game) review. Users can create many posts. Users can reply to a post. Posts can receive many replies. Reviews are written by users for a game. A user can write many reviews. A game can have many reviews. HINTS: RQ1: Users own game copies not the actual games. RQ1: All user objects are managed by a user manager object in the system (design decision). RQ5&RQ6: Users own collectible items not actual collectibles.…

Engg From the , pick any one use case of your own choice and derive test cases for it Scenario An automated teller machine (ATM) or the automatic banking machine (ABM) is a banking subsystem that provides bank customers with access to financial transactions in a public space without the need for a cashier, clerk or bank teller. Customer uses bank ATM to check balances of his/her bank accounts, deposit funds, withdraw cash and/or transfer funds after authentication. ATM Technician provides maintenance and repairs and Bank provides money and other services. If needed, customer may ask ATM for help. Authentication is done by inserting a plastic ATM card and entering a personal identification number (PIN). Maintenance includes Replenishing ATM with cash, ink or printer paper, Upgrades of hardware, firmware or software, and remote or on-site Diagnostics. Diagnostics also includes in (shared with) Repair use case
- Assume you were hired to design a Car Rental System. The system will keep track of the cars and the customers who will rent the cars. The system will be managed by an administrator and will be operated by several employees.(A) Choose any of the Use Cases that you have used and write the use case textual description for it with all the main sections(Identifier and name, Initiator, Goal, Precondition, Postcondition, Assumptions, Main Success Scenario, Extensions). please expain this definations. (B) Develop an Activity Diagram for the Main Success Scenario and its Extensions that you have listed in above and make sure to have at least 10 activities. Note: for a good grade, you need to make good use of the different design symbols (Such as Decision nodes, Merge Node, Swimlane, Synchronization bar) if possibleA rental company has the following procedure: A customer reserves a car, picks it up and the returns it after a certain period. At the time of pickup, the customer has the option to buy or waive collision insurance on the car. When the car is returned; the customer receives a bill and pays the specified amount. Corporate customers are not billed directly, rather the companies they work for are boiled and payments are made some time later.
