Expert Solution & Answer
Check Mark
Program Plan Intro

E-R model:

  • It is a tool for creating data model.
  • It is used for developers to describe the content of data model by using two functions called entities and relationships.

Entity:

  • It helps the user for tracking something in database.
  • Example entities in student database system are Student, Grade, Course, etc.

Relationships:

  • Entities have relationships among each other.
  • For example, in student database, a Student has a relationship to Major and Student has a relationship to Advisor.

Attribute:

  • It used to describe the entity characteristics.
  • Example attributes of student entity is Student_id, Student_name, Student_address, etc.

Identifier:

  • It is an attribute or group of attribute, but its value is related with one and only one entity instance.

Explanation of Solution

Entity Relationship diagram that displays relationship among the database, database application and users:

The below is the E-R diagram that shows the relationship that is laid among the database, database application and users:

Using MIS (10th Edition), Chapter 5, Problem 5.1UYK , additional homework tip  2

User:

The person or end user that can process the application that is stored in the database.

Database application:

A database application is a collection of four elements namely forms, reports, queries and application which acts as an intermediate between the user and data of the database

Database:

Database is a collection of information that is used to store and retrieve the data. Data is organized in tables.

Explanation of the E-R diagram:

  • Many user can use the database application.
    • Example of the user entity could be “students”, “faculty”.
  • Many database applications can be present in a single database.
    • Example of the database application could be “Bookstore”,”Library”.
  • Only one database can contain many database application.
    • Example of the database could be “studentDB”,”BookStoreDB”.
  • The relationship between the user and the database application is “M:N (Many to many )relationship.
  • The relationship between the database application and theDatbase is “N:1”(Many to One) relationship.

Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…
