Chapter 5, Problem 2ARQ
Explanation of Solution
Database is a collection of information that is used to store and retrieve the data. Data is organized in tables.
Hierarchy of Data:
The hierarchy of data is specified in tree-like structure. The records are connected through links. The database elements are,
- Table or File
- Records or Rows
- Fields or Columns
- Bytes or Characters
Metadata:
Metadata gives information about other data or simply, it is a data about the data.
- It provides the description about the characteristics or properties of end user data and environment of the data.
- The environment includes the source of the data, where it is stored, usage, and so on.
- It gives all the information about a data.
Relationship among the rows:
- Using the examples of “student” and the “office_visit” tables the relationship can be described as one to one relationship.
- Because the student number in the “student” table and the student number in the “office_visit” table have the unique student number.
- If any modification is made concerning the student number in the “student” table, then it is automatically updated in the “office_visit” table...

1. Create a Person.java file. Implement the public Person and Student classes in Person.java, including all the variables and methods in
the UMLS.
Person
-name: String
-street: String
-city: String
+Person(String name, String, street, String, city)
+getName(): String
+setName(String name): void
+getStreet(): String
+setStreet(String street): void
+getCity(): String
+setCity(String City): void
+toString(): String
Student
-Id: int
+Person(String name, String, street, String, city, int Id)
+getId(): int
+setId(int Id): void
+toString(): String
2. Create a StudentTest.java file. Implement a public StudentTest class with a main method. In the main method, create one student
object and print the object using System.out.println().
Your printing result must follow the example output:
name: Mike, street: Morris Ave, city: Union, Id: 1000
Hint: You need to modify the toString methods in the Student class and Person class!

- Python - need help creating a python program that will sum the digits of a number entered by the user. For example if the user inputs the value 243 the program will output 9 because 2 + 4 + 3 = 9. The program should ask for a single integer from the user, it should then calculate the sum of all the digits of that number and output the result.arrow_forwardI need help with this in Python (with flowchart): Im creating a reverse guessing game. Then to choose a random number from 1 to 100 and the computer program will attempt to guess it, displaying the directions calculated or not. The guess will be displayed and the user will answer if it was correct or not. If correct, the game ends, if not then the computer asks if the guess was too high or too low. Finally inputting an answer and the computer generates a new guess within the proper range. Oh and to make sure the program doesnt guess outside of the ranges produced by the inputs of “too high” and “too low”. The program ending when the user guesses correctly or after the program takes 6 guesses. HELP ASAP!arrow_forwardI need help with this in Python (with flowchart): Im creating a reverse guessing game.
