Create a CRUD matrix to check the consistency between your domain model class diagram (create it) and your complete list of use cases (create and list them). Set this out in the form of a table with classes as the columns and use cases as the rows. Weddings, Parties, Everything is a rapidly-growing online business that links together customers who need a caterer for their event with businesses that provide catering. Customers input their location and requirements, and are presented with a shortlist of potential caterers who may be able to provide what they need.WPE has been partly manual for the first few months of their operation, but now needs new system to automate business of putting together the right customer with right caterer. intend to roll system out nationally, from original base in WA. Edison Guacamole, owner/manager of WPE, has contacted you for help.two sides to system are, caterers & customers.Caterers register on WPE system by providing business name, description,…
Can you please create an ER diagram model for the Open Kattis System website. For the ER diagram, you need to model the data that would be needed to recreate all of the web pages that are displayed to ordinary contest observers or participants on OpenKattis. You do not need to model any additional data that is revealed only when you set up a contest, or create a new problem.

Add the CRC index cards to Appendix E of your SRS document under class diagrams. B Based on the responsibilities and collaborations identified in your CRC index cards update your first cut domain class diagram with the following: a. Class attribute descriptions and visibilities b. Signature methods with the respective parameters and visibilities Add the class diagram to Appendix E of your SRS document under class diagrams.

From the below Class Diagram it looks that the number of registrations are unlimited as the number of attendants are specified from 0 to *. However, this is actually a flaw in the UML that we cannot put constraint on objects or on the instances. Suppose that the No of Registrations is restricted to 50 or 300 depending on the type of Webinar. Draw an OCL model for the supposition we made i.e. put a constraint on the number of registrations in the webinar.
Think of a classification problem from your own experience and interest (e.g., distinguishingbetween two types of things/living beings/weather/personality/vehicle/industry/sports/houses/professionals etc.) Collect some real-world data to solve that classification problem. Have at least two classes, two attributes and atleast 5 instances per class. Create a dataframe with this data and paste a screenshot of it. Also give a short description of the data (number of instances, number of attributes and the list of attributes and list of classes). The attributes should be numerical. The classification problem should be a new one, but the dataset may contain data that are new (generated by you by any rough measurements) or collected from public domain. Please cite the references/sources from which you collect the data.
Draw a partitioned activity diagram for the rent car use case of Rent-A-Car. Rent-A-Car company has a website through which a user is allowed to book and pay for their rental cars. When a customer makes a request to rent a car the customer is presented with different car models from the catalog. The customer selects a model. The system checks if a car is available for the model selected. If a particular car is not available, the customer is requested to choose a different model. If the chosen model is available, the rental price is displayed to the customer. The customer needs to confirm if they would like to proceed with renting the car at that price or would like to opt for a different model. If the customer decides to proceed with booking the car, they must upload their driver’s license for verification. The driver’s license is verified by a staff member once it is uploaded. Only if the license is valid, does the system deduct payment and deposit from the clients credit card. If…

By using Creately tool, draw the class diagram corresponding to the following scenario:• Each university has one or more department• Each department has a chairperson which is a lecturer and surely it assigns others• Each course object maintains a list of the students on that course and the lecturer who has beenassigned to teach that course• The course has behaviour that allow the adding and removing of students from the course,assigning a lecturer, getting a list of the currently assigned students, and the currently assignedlecturer.• The “taughtBy” relationship shows that a Course only has a single lecturer, but that a lecturermay teach several Courses.• Each Lecturer object also maintains a list of the Courses that it teaches.• There is a similar relationship between Course and Student. A course is attended by zero ormore Students, and a Student may attend multiple courses.• Both Lecturer and Student are shown to be types of Person.
