using both order number and product code together as a primary key for an order entry system is used to elimiate what type of relationship

Answers

Answer 1

Using both order number and product code together as a primary key for an order entry system is used to eliminate the many-to-many relationship.

What is a primary key?

A primary key is a unique identifier that allows a user to recognize individual records in a database table. In a database, a primary key is used to define a specific record in a table. This identifier is a distinct set of one or more fields or columns that are used to retrieve records.

The purpose of using both the order number and the product code together as a primary key is to create a unique identifier for each order and eliminate any duplicate records.

It is possible for an order entry system to have a one-to-many relationship with product codes, implying that a single order number might have several product codes or items associated with it.

A(n) ________ is a specific piece of information that is stored in every record.

Answers

A(n) attribute is a specific piece of information that is stored in every record. Attributes are used to describe and characterize the data in a database. They define the properties and characteristics of the entities in the database and provide details about them.

In other words, attributes define what kind of information can be stored in a particular field within a record. Attributes can be of different types, such as alphanumeric, numeric, date, or boolean, depending on the nature of the data they represent. For example, in a database of employee records, attributes could include the employee's name, ID number, date of birth, salary, and job title. Attributes are essential in organizing and structuring data within a database. They enable efficient retrieval, sorting, and filtering of data based on specific criteria.

Furthermore, attributes play a crucial role in establishing relationships between entities in a relational database. By defining attributes, we can establish the connections and dependencies between various records and ensure the integrity and accuracy of the data. In summary, attributes are specific pieces of information that are stored in every record. They provide detailed descriptions of the data and enable efficient data retrieval and organization within a database.

write a recursive, string-valued method, replace, that accepts a string and returns a new string consisting of the original string with each blank replaced with an asterisk (*)

Answers

The recursive, string-valued method, replace, that accepts a string and returns a new string would be one that checks if the string 's' is empty.

How to write the method?

An example of a recursive method written in Java is :

public class Main {

public static void main(String[] args) {

System.out.println(replace("This is a sample string."));

}

public static String replace(String s) {

if (s.isEmpty()) {

return s;

} else {

char first = (s.charAt(0) == ' ') ? '*' : s.charAt(0);

return first + replace(s.substring(1));

}

In this code, the replace method checks if the string s is empty. If it is, it simply returns the empty string (this is the base case of the recursion). If s is not empty, it checks if the first character of s is a blank space.

you are connecting a switch to a router. you just made a cable with each end configured differently, one 568a and the other 568b. when you plug in the cable, the devices cannot communicate. what is the most likely cause?

Answers

The most likely cause for the devices not being able to communicate when connecting a switch to a router with a cable that has one end configured as 568A and the other end configured as 568B is a mismatch in wiring standards.

What are the 568A and the 568B wiring?

The 568A and 568B are two different wiring standards used for Ethernet cables. In order for devices to communicate properly, both ends of the cable need to follow the same wiring standard.

Considering the given situation, maintaining uniformity in the wiring standard used on both ends of the cable would be the best course of action. Either utilize a pre-made cable with consistent wiring standards with either 568A or 568B on both ends or re-terminate one end of the cable to match the same standard as the other end.

Mary needs to buy 4 yards of fabric if she wants to sew 2 shirts. Since the given quantity of fabric can only make 1 shirt, she would need to double that amount to accommodate the production of 2 shirts. Each shirt requires a certain length of fabric to cut out all the necessary components, including the front, back, sleeves, and any additional details. By purchasing 4 yards of fabric, Mary ensures that she has enough material to complete both shirts without running out. This accounts for any variations in fabric patterns, potential mistakes during cutting, and allowances for seams and hems. Having a sufficient quantity of fabric eliminates the risk of not having enough to complete the second shirt, ensuring that Mary can successfully sew 2 shirts for her school's drama department.
