Question 2:Develop a Domain Class diagram based on the following narrative. Note any ambiguitiesthat you have as you develop the model. If you need to make assumptions, also note them.Make sure to show attributes, multiplicities and aggregations/compositions, whereappropriate.Consider the world of libraries. A library has books, videos, and CDs that it loans to itsusers. All library material has an id# and a title. In addition, books have one or more authors,videos have one producer and one or more actors, while CDs have one or more entertainers. Thelibrary maintains one or more copies of each library item (book, video or CD).Copies of all library material can be loaned to users. Reference-only material is loaned for 2hrsand can't be removed from the library. Other material can be loaned for 2 weeks. For every loan,the library records the user, the loan date and time, and the return date and time. For users, thelibrary maintains their name, address and phone number.

The given problem is related to UML modelling where the description of the problem indicates the…

Synthesize the domain model of vending machine which has the following characteristics. Products can be purchased by inserting the correct number of coins into the machine. A user selects a product from a list of available products, adds coins, and either gets the product or gets the coins returned if insufficient money was supplied or if the product is sold out. Products can be restocked and money removed by an operator. Requirements for this system: Product Selection: Users will be able to choose a product from a list of available items. The system must display the product list with corresponding prices. Coin Insertion: Users can insert coins into the machine to pay for selected products. The machine will accept common denominations. Purchase Process: Upon sufficient coin insertion, the selected product will be dispensed. If the inserted coins are insufficient, the machine should return the coins. In case of a sold-out product, the machine will return coins. Restocking: Operators…

Create a student registration class diagram for all requirement that contains at least 15 class, necessary relations and types. Include important attribute of class. Use three of the patterns in your class design using at least one creational, structural, and behavioral in an integrated way. (it should be written and show which patterns are used). The design should be homogenate. Excessive usage of any property type, object type, or function type is not suitable. For example, for creating 10 relations between classes, the number of relation types for aggregation, composition, etc. should be near to each other.

The requirements below partially describe a game management system (such as Steam) that is used for managing game installations of a player. 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. 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. Each…
