Q1. Draw an E-R Diagram for the following situation. At the university system each STUDENT must be assigned an ADVISOR who counsels students about degree requirements and helps students register for classes (COURSE). Each student must register (REGISTRATION) for classes with the help of an advisor, but if the student's assigned advisor is not available, the students may register with any advisor, We must keep track of students, the assigned advisor for each, and the name of the advisor with whom the students registered for the current term. Tips: Attributes of STUDENT include Student ID (the identifier), Name, and Major. Attributes of ADVISOR include Advisor ID (the identifier), Name, and Department. Attributes of COURSE include Course ID (the identifier), Title, and Credits. Attributes of REGISTRATION include Semester, and Year. Based on your background, think of logical and standard relationships between the given entities.

Create UML diagram for this:  Layers of gasses are given, with certain type (ozone, oxygen, carbon dioxide) and thickness, affected by atmospheric variables (thunderstorm, sunshine, other effects). When a part of one layer changes into another layer due to an atmospheric variable, the newly transformed layer ascends and engrosses the first identical type of layer of gasses over it. In case there is no identical layer above, it creates a new layer on the top of the atmosphere. In the following we declare, how the different types of layers react to the different variables by changing their type and thickness. No layer can have a thickness less than 0.5 km, unless it ascends to the identical-type upper layer. In case there is no identical one, the layer perishes.

19. Most activities in a network diagram have a finish-finish relationship.     True   False

Create an Interaction Model Use Case Model 1. Create use case summaries for a Employee Payroll System, Some suggested names are: Enter employee information, Print employee pay Snub, Perform maintenance, Perform backup, View employee records, etc. 2. Create a use case description for “Print Employee Pay Snub"...You should have several use case descriptions but only list one for this assignment. 3. Create a Use Case diagram for an Employee Payroll System, Include at least 3 actors. Sequence Model 1. Create a Scenario for a sequence of events that occur during one particular execution the system This should be listed as one of the actors (or whatever you chose to name them) in the use case diagram. 2. Create a Sequence Diagram Note: there should be a Sequence diagram for each Use Case listed in your use case summary, (if there are 4 Use Cases there should be 4 Sequence Diagrams).

Draw an ER Diagram for the following Business Situation: A bank has a phone call system in which the costumer can call and talk to one employee and inquire of their existing account. Costumer can have two type of accounts, checking account or savings account, client can own both type of accounts. One of the assumptions which is being made with this project is all interactions will be over the phone. Clients would call in to the business’ account representatives who will have to search the client in internal database. Once the client has been searched in the database, representative will go forth and verify the client via personal information displayed through the database. Personal Information would include, full name, address, last 4 of social security, and account number. The project will assume that the business is domestic, and all clients are in the United States. Once the client is verified, representative can discuss business related queries, including transactional questions…

1. Create an EER diagram to keep track of information for an art museum given that the following criteria is met:   The museum has a collection of art objects. Each art object has a unique identification, an artist (if known), a year (when it was created, if known), a title, an epoch (Renaissance, Modern, Ancient, etc.), and a description. The arts objects are classified in the museum in several ways as discussed below:  Arts objects are categorized based on their type. The main types are: painting and sculpture, plus another type they called “other” to accommodate objects that do not fall into one of the two main types.   A painting has a paint type (oil, watercolor, etc.), material on which it is draw on (paper, canvas, wood, etc.), and style (modern, abstract, impressionism, etc.).   A sculpture has a material from which it was created (wood, stone, iron, etc.), height, weight, and style.   An art object in the other category has a type (print, photo, etc.) and a style.  Art objects…

Can you please explain this with a diagram and the steps to follow together with the diagram?

here are many different types of interaction diagram, each of which emphasizes a different aspect of the interaction.
