develop an Entity Relationship Diagram for the application described in the following paragraph. Pick and Shovel Construction Company is a multi-state building contractor specializing in medium-priced town homes. Assume that Pick and Shovel's main entities are its customers, employees, projects and equipment. A customer can hire the company for more than one project, and employees sometimes work on more than one project at a time. Equipment, however, is assigned to only one project at a time. Draw an ERD showing those entities.

Make a UML Class Diagram based on the following scenario: As a Software Analyst in Techno Bhd., you have been assigned by your Project Manager to model an SUV Rental Provider App using UML. The SUV Rental Provider App has two types of system users namely Client and Admin. The client, who can be Member or Non-Member can search for SUV models and daily rental. Each SUV model consists of SUV model details and daily rental. Thus, the Client can choose to view the SUV model details such as description and images and daily rental based on the types of the selected model. Only Member and Admin are required to log in to access the system. Member gains access to additional services. The additional services for members are: manage a reservation, check membership details, change password, manage credit card and banking information, and log out. Each Member is entitled to reserve up to 10 SUVs. When a member makes a reservation, he/she has to specify the selected SUV model and the number of rental…

Draw a complete ER-diagram for the following case. A lecturer (having an ID, name and room number) is responsible for organizing a number of course modules. Each module has a unique code and also a name and each module can involve a number of lectures who deliver part of it. A module is composed of a series of lectures and sometimes lectures a on a given topic can be part of more than one module. A lecture has a time room and date and is delivered by a lecturer and a lecturer may deliver more than one lecture. Students, identified by number and name, can attend lectures and a student must be registered for a number of modules. We also store the date on which the student first registered for that module. Finally, a lecturer acts as a tutor for a number of students and each student has only one tutor. Also show relational database schema including Primary and Foreign key constraints. (Please draw this on a paper)
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.
Question 2 Draw an activity Diagram in draw.io and screenshot it for me. Scenario Each subject has 1 lecture class and 4 tutorial classes. Each lecture class can have a maximum of 80 students only and each tutorial class can have a maximum of 20 students only. From the system, the faculty will generate a list of subjects that have registered students. Then the list of academicians for the faculty is displayed. For each academician, the faculty can assign either 1 lecture class or 3 tutorial classes. The faculty will keep assigning duty to the academicians until there are no more lecture or tutorial classes.
