- Draw an ER Diagram with cardinalities. In an organization, there are different Employee (EmpId, Ename, Job) are working in different Departments (DeptNo, DName, Loc). A particular Employee can work exactly in one department where as in a specific department there must be one employee at least employed. An employee may work on one more Project (ProjID, Proj_Name, Budget) or may not working on any project and there must be at least one employee working on a particular project. Organization also wishes to record enter-date and job for a particular employee working on a specific project.Create a class diagram to keep track of staff bookings.

- Question: For this assignment, you are required to draw use case diagrams and activity diagrams for the Professional and Scientific Staff Management (PSSM) case you were provided. Please make sure you provide thoughtful and professional diagrams. Additionally, provide use case descriptions. I highly recommend that you use Lucid chart (the free version is sufficient). This is the feedback I received: the main part of this assignment is missing (use case and activity diagram), and that missing part connects to the remaining part of this assignment (USE case description). Can you please add this to my report?Please draw a use case diagram from the below activity diagram .As a project manager of a Software project, you have received given data about the different type of Issues identified in the project: – Issue 1 – 85 occurrences; Issue 2 – 125 occurrences; Issue 3 – 28 occurrences; Issue 4 – 395 occurrences; Issue 5 – 185 occurrences; Issue 6 – 128 occurrences; Issue 7 – 85 occurrences; Issue 8 – 169 occurrences; Issue 9 – 148 occurrences; Issue 10 – 209 occurrences. Which diagram you will use to prioritize the Issues? Generate the diagram using any tool and paste it here.
- I'm designing an ER diagram for a project and I have to represent an entity called User, with the attributes: Username, Password and Role.

Either way, how would it be represented in the ER diagram? (if it was an attribute or two entities)System models, if you will. How should preliminary models be constructed?Develop an activity diagram based on the following narrative. Note any ambiguities or questions that you have as you develop the model. If you need to make assumptions, also note them. The shipping department receives all shipments on outstanding purchase orders. When the clerk in the shipping department receives a shipment, he or she finds the outstanding purchase order for those items. The clerk then sends multiple copies of the shipment packing slip. One copy goes to purchasing, and the department updates its records to indicate that the purchase order has been fulfilled. Another copy goes to accounting so that a payment can be made. A third copy goes to the requesting in- house customer so that he or she can receive the shipment. Once payment is made, the accounting department sends a notification to purchasing. Once the customer receives and accepts the goods, he or she sends notification to purchasing. When purchasing receives these other verifications, it closes the purchase…
- Create an ER/EER diagram for the following 1. Professors have an SSN, a name, an age, a rank, and a research specialty. Projects have a project number, a sponsor name (e.g., NSF), a starting date, anending date, and a budget. Graduate students have an SSN, a name, an age, and a degree program (e.g., M.S.or Ph.D.). Each project is managed by one professor (known as the project’s principalinvestigator). Each project is worked on by one or more professors (known as the project’s co-investigators). Professors can manage and/or work on multiple projects. Each project is worked on by one or more graduate students (known as the project’sresearch assistants). When graduate students work on a project, a professor must supervise their work on the project. Graduate students can work on multiple projects, in which case they will have a (potentially different) supervisor for each one. Departments have a department number, a department name, and a main office. Departments have a professor (known…Create an ER/EER diagram for the following 1.

Hilltop is an old-line dealership, and the prior owner was slow to change. A new management team has taken over, and they are eager to develop a first-class system. Right now, you are reviewing the service department, which is going through a major expansion. You decide to create a model of the service department in the form of a use case diagram. The main actors in the service operation are customers, service writers who prepare work orders and invoices, and mechanics who perform the work. You are meeting with the management team tomorrow morning. How would you create a draft of the diagram to present to them?
