Answer:
1) Yes, Publisher relation should have a publisherID primary key.
2) NOT NULL and UNIQUE for the BookID, BranchID, CardNumber and name of the borrower in the Book, Book_Copies, Library_branch, and Borrower relations respectively. The DueDate field of the book_loan relation must be a time constraint. The BookID of the Book relation must be serial number for automatic addition and update of bookid across the database.
Explanation:
The Publisher relation should have primary key publisherID which should replace the publisherName in the Book relation to easily make a join query and attain a third-level database model.

What is one similarity between compiled and interpreted programming languages? (5 points)
Both compiled and interpreted languages are translated one line of code at a time before moving to the next line.
Both compiled and interpreted languages can be shared with others while keeping the source code private.
Both compiled and interpreted languages are high-level languages and translate code for a computer to understand.
There are no similarities between compiled and interpreted programming languages.
Answer:
Both compiled and interpreted languages are high-level languages and translate code for a computer to understand.
Explanation:
The one similarity between compiled and interpreted languages is that they are both high-level languages.
A high-level language is a computer language written in easy to understand human language which is then converted to machine code for the computer to understand.
A high-level language can either be interpreted or compiled.
An interpreted is a language in which the code is translated line by line before execution while a compiled language is one in which the source code is converted directly into machine language before execution.
So, the similarity between both languages is that they are high level languages and translate code for a computer to understand.
By limiting the number of times a person can use a type of software before registering as the authorized owner of that software, software firms are dealing with problems associated with:
Answer:
Software piracy.
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.
Simply stated, it's a computer program or application that comprises of sets of code for performing specific tasks on the system.
Basically, softwares are categorized into two (2) main categories and these are;
I. Open-source software.
II. Proprietary software.
A proprietary software is also known as a closed-source software and it can be defined as any software application or program that has its source code copyrighted and as such cannot be used, modified or distributed without authorization from the software developer. Thus, it is typically published as a commercial software that may be sold, licensed or leased by the software developer (vendor) to the end users with terms and conditions.
Some examples of proprietary software are Microsoft Windows, macOS, Adobe photoshop etc.
Furthermore, a proprietary software license avail end users the opportunity to install and use the software after agreeing to the terms of its license.
Software piracy can be defined as an act which typically involves the unauthorized use, duplications, or distribution of a software that is legally copyrighted or protected, without an express permission from the software manufacturer (owner).
Generally, software manufacturers (owners) deal with problems associated with software piracy by placing a limit on the number of times or durations that an end user is allowed to use a particular software before registering (subscribing) as the authorized owner of that software.

Roger wants to give semantic meaning to the contact information, which is at the bottom of the web page. To do this he will use a footer element as a ______ of the contact information.
Answer:
Parent
Explanation:
HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.
Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of a HTML document contains the contents or informations that a web page displays.
In this scenario, Roger wants to give semantic meaning (an element conveying informations about the type of content contained within an opening and closing tag) to a contact information placed at the bottom of a webpage. Thus, in order to do this, he should use a footer element as a parent of the contact information and as such all instance variables that have been used or declared in the footer class (superclass) would be present in its contact information (subclass object).

The program should contain the following:
Welcome message- Display your full name, project name and give a small description on your project (definition of the BMI) [2 marks]
Variables :
height variable , input by the user [2 marks]
Weight variable , input by the user [2 marks]

Write an expression that evaluates to true if the value of the int variable widthOfBox is not divisible by the value of the int variable widthOfBook. Assume that widthOfBook is not zero. ("Not divisible" means has a remainder.)
Answer:
The expression is:
if widthOfBox % widthOfBook != 0
Explanation:
Given
Variables:
(1) widthOfBox and
(2) widthOfBook
Required
Statement that checks if (1) is divisible by (2)
To do this, we make use of the modulo operator. This checks if (1) is divisible by 2
If the result of the operation is 0, then (1) can be divided by (2)
Else, (1) can not be divided by (2)
From the question, we need the statement to be true if the numbers are not divisible.
So, we make use of the not equal to operator alongside the modulo operator
