Using UML class diagrams, create a design for the following (you can defer declaring the types for any instance variables and instance methods as long as you represent the concepts appropriately). NB: You may hand-draw your diagram or use a drawing program (your choice). Upload your finished answer for (a) and (b) as one file. (a) An Employer has one or more Employees. An Employee has exactly one Employer. Employees have attributes for their name, salary and job title (b) We are producing a vehicle registration system for the local DMV/RMV. Model the following using a UML class diagram. Read the entire specification before proceeding (this is ONE question, broken into 4 segments for readability): (i) Our interface (protocol/contract) IVehicle states that all vehicles can register() and calculateExciseTax(). These operations are public and the Vehicle contract is stable – it will not change. (ii) We think we’ll be able to take advantage of code-reuse, so your team must introduce an…

1. Design and implement the class modeled in the diagram in figure 1 in C ++. Review some basic requirements that you should consider in the Specifications section. 2. Design test cases that allow you to test general cases of your class. 3. Place in the diagram (figure 1) the type of appropriate relationship between the| classes if a Date class attribute is used in the Employee class. 4. Based on the test cases, add a console application that allows you to implement the test cases.

You will be required to submit an informational abstract by the end of unit 6. Your abstract should be no longer than one (1) page and it needs to include the key elements of an informational abstract. The abstract will be written based on the topic you have selected. The main goal of an informational abstract is to inform the viewer on your research. Its main purpose to provide your audience with a clear idea of what you research is about through the summarization of your main points, key information, and findings. Your abstract must include the following:• Background: Write two or three sentences introducing your research. Provide your audience with context for your project.• Goals: Write two to three sentences providing the purpose of your research.• Methods: Write two to three sentences explaining how you performed your research. You are not expected to carry out any experiments here, and it is anticipated that most of your research will come from reading various online sources.…
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.
