An Entity Relationship (ER) Diagram is a type of flowchart that illustrates how “entities” such as people, objects or concepts relate to each other within a system. Consider the following description of a system: A university registrar’s office maintains data about following entities: Courses, including number, title, credits, syllabus, and prerequisites. Course offerings, including course number, year, semester, section number, instructor, timings and classroom. Students, including student-id, name, and program. Instructors, including identification number, name, department, and title. Furthermore, the enrollment of students in courses and grades awarded to students in each course they are enrolled for must be appropriately modeled. Construct an ER Diagram for the registrar’s office. Document all assumptions that you make about the mapping constraints.
Case 1: Create a use case diagram based for the system that follows. Consider the following Pet Groomers Appointment system: When making a booking, pet owners need to fill a booking form that states their name, address, phone number, and the pets' details such as pet name, breed and age. Owners will also enter their preferred date of appointment such as day and time. The admin receives the booking form and checks the groomer's schedule to see whether the time slot is booked. If the slot is free, the booking is scheduled and confirmation will be given. However, if the slot is booked, the admin will suggest the next available slot based on the day and time entered. If the pet owner agrees, they will confirm the booking and it will be scheduled. An assigned groomer will receive the booking under their schedule. The system will send a reminder to the owner 3 days before their appointment.
Modify the following system sequence diagram to reflect the following: 1)The sales clerk can add more than one item to the ticket, every time they add an item, the system returns the price and description. 2) After displaying the total, only if the receipt was requested, the system returns the receipt. Sales Clerk validate Contractor (name or ID) contractor information create Ticket () additemto Ticker (item ID, quantity) price, description total := endSale () printReceipt() receipt System
Create an Activity Diagram for the “Order Item(s)” or “Purchase Item(s)” use case (or chain of use cases). The name that you have given this Use Case or group of Use Cases may differ, but it should be quite a comprehensive Use Case(s) that should encapsulate the following: Customers buying non-prescription items. Customers buying prescription items. Customers buying any number of items at once (i.e. 1 or more). Order fulfillment by warehouse staff. Order fulfillment by pharmacists. This Use Case does NOT need to encapsulate: Customers browsing or searching for items. Customers logging into or creating accounts. Customer payment.Attached will be more information on the Pharm@Home System
Create a use case sequence diagram using the information below. Buy Parts Customer/Store Employee Description: This use case describes car parts dealer purchasing. Successful Finish: client requests vehicle component 2. Store associate verifies availability 3. component is available and client pays cost 4. Customer receives part; stock adjusted. 1. Customer asks auto part 2. Store Associate checks part availability 3. Part is unavailable and customer chooses to order part or no part 4. Customer receives part and stock is updated (if alternate part ordered) or leaves without part. Alternative: Customer wants component. No post-condition No assumptions
You are asked to design a sequence diagram to describe the interactions of a part of a library system. This part can be described as a use case. In this use case, a librarian uses the system to check out an item for a legitimate borrower. First, the system needs to check the borrower's record. Second, check if the item is available or not, then update the library data, the borrower's record, etc. Use the following class diagram and details to get information about the system. Record CheckOut LibraryData recordlsGood checkRecord() addToRecord() checkData() changeData() available 1 1 requestCheckOut() 1 *
Generate an Activity UMLdiagram that starts with the customer connecting with the web site and ends with the order available for pickup or ready for delivery. This should be a very focused and specific UML Activity diagram. Note that the workers will also interact with the process at some point - identify the step or steps where the workers interact with the system. The activity diagram must contain a minimum of 15 elements. *** Number each element of the activity diagram. ***

Write an algorithm on how to withdraw money from an ATM. Shopping Made Easy System A customer uses Shopping Made Easy System for online shopping. System requires the customer to sign up and sign in to be able to interact with the system. Customer registration is verified by the administration. A customer may use the portal as a guest without signing up but is only able to view catalogues in case of a guest. A customer can manage his/her account which involves signup/sign in and profile management. A customer can browse through catalogues to view different products; customer can also search for a specific catalogue by name or code number. Customer can view the products and can log out without buying. Another main feature of the system is Shopping cart management. Customer can add or remove items in cart. Customer can…
Review the UML diagram provided for a game software application. A text version is available: Text Version for UML diagram Word Document. You may notice that it is incomplete - it is missing attributes and methods, and only includes a small portion of a complete game application. This is quite common! As a software developer, typically you will be given pieces of the puzzle or tasks to complete as part of a larger project and as a member of a larger team. It takes practice to focus on the information you are given to determine what you have and what steps you need to take to complete the task. Specifically, the game application requires that only one instance of the game be able to exist in memory at any given time. This can be accomplished by creating unique identifiers for each instance of the game. Complete the UML diagram to accurately represent a singleton pattern for the Game Service class. You should replace the question marks in the UML diagram with appropriate static and…

Entity-Relationship Diagram (ERD) is one of the data modeling tools that provides a software engineer with the ability to represent data objects, their characteristics, and their relationships. Use an ERD to describe the following scenario. A teacher is identified by an ID number (TID), last name (LName), and first name (FName). A project is identified by a project ID (PID) and title (T). A student is identified by an ID number (SID), last name (LName), and first name (FName). A teacher can supervise zero, one, or many students and a student is supervised by one teacher. A teacher must propose one or many projects and every project is proposed by one teacher. A student must work on one project and every project is worked by only one student.
