- You are designing the access control policies for a Web-based retail store customers access the store via the web, browse product information, input their address and payment information, and purchase products. Suppliers can add new products, update product information, and receive orders. The store owner sets the retail prices, makes tailored offers to customers based on their purchasing profiles and provides marketing services. Draw a class diagram, sequence diagram for the given scenario also write down the access control policy for the roles of customer, supplier and store administrator.1. Create the initial ER diagram for a car dealership. The dealership sells both new and used cars, and it operates a service facility.

You can submit an application through the CEN website's online portal. following the creation of a new user account the user can select his own measurements, such as arm length, hand length, shoulder breadth, and so on. Customers can choose from a range of styles on the website. The order is placed in the shopping cart after the user selects the suit style. After making the user selections, the user can select the appropriate customizations, such as fabric color, fabric type, and other options. After the suit has been customized, the site tailors the suit that the customer has chosen, which takes around 5 weeks, and the order is delivered to the customer. Payment is due when the order is received.Given the following Business case scenarios I need help creating UML activity diagrams to highlight the main activities. Business Use Case 1: Patient Admission Scenario: Patient Arrival: A patient arrives at the hospital for treatment. Registration: The front desk staff registers the patient in the HIS, capturing personal information and assigning a unique identifier. Insurance Verification: The HIS verifies the patient's insurance information to facilitate billing processes. Medical History Entry: The healthcare provider enters the patient's medical history into the HIS. Assigning a Room: Based on the patient's condition and availability, the system assigns a hospital room. Treatment Plan: The healthcare provider develops a treatment plan, documenting it in the HIS. Medication Orders: Medication orders are entered into the system for the pharmacy to prepare. Nurse's Care: Nursing staff access the HIS to view the treatment plan and administer…

Describe the participants and collaborations. Please respond to all of the above 4. There is a system configured to work with three pretzel stores: Pretzel Maker, Wetzel, and Auntie Anne's. They create similar yet custom-made pretzels, and the system needs to be independent from the way the pretzels are created. Each pretzel store uses its own ingredients (products), yet similar to the other stores. They each use their own kind of dough, cheese, and sauce.Items for mobile users are controlled through a "Application Store" interface. Users may browse, download, and install items of interest on their mobile device from the "Application Store." To portray the aforementioned scenario, you must create an Entity Relationship Diagram (ERD). Use proper cardinality and modality among ERD entities.
