Unit title(s): Creating Database Driven Web PagesUnit code(s):
Learner:Tutor/Assessor:
Description of Assignment: This assignment is both a written and practical assignment that will demonstrate your skills in the creation of database driven web pages TASK 1 Create a MySQL database containing a single table (games) for an online games store. The games table will store information about games with the minimum of the following fields: game title, genre, year of release, publisher, screenshot, and a written review and (possibly) other fields of data relating to games. Choose appropriate data types and widths for each field. Note 1) As your database server might not allow you to choose the database name any name is acceptable for this Note 2) The screenshot data does not need to be stored inside the table. Commonly this will contain a local file path or URL that can be used as a web hyperlink Use PhpMyAdmin to add 5 records to the games table based on existing information which you will research on existing games websites. Create a username and password that can access this database using your firstname+lastname and a password of your own choice. This account should have full access to the database. Create a webpage that connects to your database using PHP. Store the information the connection needs (database name, table name, username /password) in PHP variables. Display a message in the webpage when a successful connection is 2.3] Create a Word document Task1 that contains A screenshot of your working webpage A well commented listing of your HTML/PHP code
Show this to your tutor to progress to the next stage
TASK 2
You will build on your work in task 1 and develop the database to the next stage Using the existing records in your games db you will need to create the following: You will create a display all records page which lists all the items in the database in a html table using a control structure [1.3] You will create an insert form to allow games to be added to the database, implement validation checks so that data is correctly entered. [4.2] [5.4] Create a complex query by creating an update page which will allow users to edit the games in the database [4.3] You will create a delete page which will allow you to delete games records in the database. [4.4] You will create a basic search engine form which allows the user to search on multiple fields on the database and give back a results page based on those fields For this You will need to create a complex query using SQL and execute this query on the remote database. This results page will use single control structures for selection and iteration such as conditional statements and loops to go through all the records. [3.1] [4.1] You will extend this page to show a list of games titles outputted as hyperlinks which then take you to more detail about the game that is chosen [3.2] [3.3] You will make a single page which has links to all these different pages you have made – all records, insert record, delete record, update records and search . Finally you will password protect access to this page [6.1] Show this all working to your tutor to progress to the next stage To document this work, you will create software documentation for the user, this will have three parts. Task 2a) Write an introductory section which explains how requirements can vary between the client (games store owner) and end user and explain the importance of an effective user experience [1.1] Task 2b) Create and justify your user interface by producing design documentation in the form of wireframes and sketches to meet the specific client requirements as outlined below. [1.2] The client requirements are The website application should work on mobile phones There should be a main menu to move between the different pages such as display all records, insert, delete What are the differences and similarities between clientside and server-side scripting, update and search Instructional text and menu labels should be intuitive There should be prompts where forms are not filled out correctly prompting the user to enter data correctly Task 2c) Create a user guide document with live links and screenshots of your working pages and well commented page listings to show your understanding. Use current web development conventions in your approach. TASK 3 You will write a report which addresses the following questions within a word limit of 1500 words. Please indicate supporting references. What are the differences and similarities between clientside and server-side scripting. Draw your conclusions by giving some practical examples of code within the types of languages involved and explain where you may use these giving real examples [2.1] Explain the environment or framework you have chosen to develop your web database application [2.2] What are the differences between (GET and POST) in relation to the published and tested multi-page scripting you have completed using request.form and query strings. [5.3] Why would you need to password protect parts of a website? [6.1] Why would you use a hidden form element on a website [6.2] Why would you need to validate user input for a website with a database? Describe the validation checks have you implemented? [5.4] Finally review and evaluate the success of your uploaded files for your web database application suggesting areas for future development [7.2]
File naming. Your tasks should be labelled in the following format

Server Hosting vs. On Premises Server Operations for Microsoft Systems

five-page paper (not including the title page or executive summary). Overview and instruction explain everything about the paper.

LRS Position Paper: Server Hosting vs. On Premises Server Operations for Microsoft Systems

Overview

A long-standing debate in the IT industry with respect to Server Hosting pertains to the debate regarding hosting servers in the cloud versus hosting them on premises. There are pro’s and con’s on both sides, both on the surface and some that will require research into current industry trends.

The objective of this exercise is to take a position in this debate and argue the merits in this debate. This paper is not designed to be a balanced report on the facts, but designed to engage you, the student, in the debate, and which solution would you choose.

Instructions

You are to construct a properly formatted research paper of five pages (not including the title page or executive summary) conforming to APA format, stating your opinion as a thesis, having at least three supports and a well-written conclusion. The supporting material should not be general talking points, but rather, demonstrate proper research and clear thought.

1) DNS – Basics

Imagine that you are trying to visit www.enterprise.com, but you don’t remember the IP address the web-server is running on.

Assume the following records are on the TLD DNS server:

· (www.enterprise.com, dns.enterprise.com, NS)

· (dns.enterprise.com, 146.54.33.180, A)

Assume the following records are on the entreprise.com DNS Server:

· (www.enterprise.com, west3.enterprise.com, CNAME)

· (west3.enterprise.com, 142.81.17.206, A)

· (www.enterprise.com, mail.enterprise.com, MX)

· (mail.enterprise.com, 247.29.126.93, A)

Diagram  Description automatically generated

Q1: What transport protocol(s) does DNS use: TCP, UDP, or Both?

Q2: What well-known port does DNS use?

Q3: How many types of Resource Records (RR) are there?

Q4: Can you send multiple DNS questions and get multiple RR answers in one message? Answer with Yes or No

Q5: To which DNS server does a host send their requests to? Answer with the full name

Q6: Which type of DNS server holds a company’s DNS records? Answer with the full name

Q7: In the example given in the problem, what is the address of the DNS server for enterprise.com?

Q8: When you make the request for www.enterprise.com, your local DNS requests the IP on your behalf. When it contacts the TLD server, how many answers (RR) are returned?

Q9: In the previous question, there were two responses, one was a NS record and the other an A record. What was the content of the A record? Answer with the format: “name, value”

Q10: Assume that the enterprise.com website is actually hosted on west3.enterprise.com, what type of record is needed for this?

Q11: Now imagine we are trying to send an email to admin@enterprise.com, and their mail server has the address mail.enterprise.com. What type of record will we receive?

Q12: In that MX record, what are the contents? Answer with the format: “name, value”

Q13: Does your local DNS server take advantage of caching similar to web requests? Answer with Yes or No

2) Comparison of client-server and peer to peer file distribution delays

In this problem, you’ll compare the time needed to distribute a file that is initially located at a server to clients via either client-server download or peer-to-peer download.

The problem is to distribute a file of size F = 5 Gbits to each of these 8 peers. Suppose the server has an upload rate of u = 85 Mbps. The 8 peers have upload rates of: u1 = 11 Mbps, u2 = 20 Mbps, u3 = 17 Mbps, u4 = 20 Mbps, u5 = 20 Mbps, u6 = 24 Mbps, u7 = 17 Mbps, and u8 = 26 Mbps The 8 peers have download rates of: d1 = 15 Mbps, d2 = 34 Mbps, d3 = 38 Mbps, d4 = 18 Mbps, d5 = 13 Mbps, d6 = 38 Mbps, d7 = 23 Mbps, and d8 = 40 Mbps

Q1: What is the minimum time needed to distribute this file from the central server to the 8 peers using the client-server model?

Q2: What is the minimum time needed to distribute the file using peer-to-peer download?

 NIT1204 Web Application and Server ManagementPractical Assignment
Due: Session 9 (Demo in lab 3)
Weight: 30% of the final grade
Group assignment:
This is a group assignment to be completed in a group of two.
Description of task:
This project will be a comprehensive Web site that demonstrates application of many of the PHP concepts covered in this unit.
You are required to develop a PHP web application to manage a shopping list i.e. Shopping List Manager application. This application requires items to be stored in a database, every item you add/modify/delete, the application updates the item in the database accordingly.
Create a user interface
The user interface for the Shopping List Manager shows the items at the top of the web page in a numbered list. The user interface also includes an add form that lets the user add a new item to the list, and it includes a delete form that lets the user delete an item from the list.
Please note that the given screenshots are sample only.
Figure 1: When the application runs for the first time
Figure 2: After adding two items in the shopping list
Implement Add, Delete and Modify Buttons
Implement “Add Item” button which is used to add shopping items in the list. Delete button is to delete the selected shopping item. Use the array_push() function to add a new item to the list. “Modify Item” button lets the user modify an existing item. If the user clicks on the Modify Item button, this code should hide the form that contains the Modify Item button, and it should display the form that displays the current item in a text box and includes buttons that lets users save or cancel their changes. Please note that add, delete and modify items should update the database accordingly.
Figure 3. When you click modify item
After you click, Save Changes, the item is updated and the page looks like as in the Figure 4.
Figure 4: After you update an item
Implement the Sort Item button
Implement that code that allows a user to sort all items alphabetically. The Sort button should be displayed only if the item list contains two or more items.
Test the application
Test your application to make sure that everything works correctly.
What to submit:
?? A cover page (A4 format) – displaying course code, course name, assignment title and student id with student’s signature.
?? Student contribution report with meeting minutes
?? Documentation including installation/usage instructions, source code, screen capture of a database and database dump file (.sql) and test report with test cases and an acknowledgement for source of external resources etc.

2,000 end stations and all server data

You are the network engineer contracted to established a WAN connectivity between two office locations for a local corporation. The main corporate headquarters has 2,000 end stations and all server data. The remote office has 550 workstation users. All users from the remote office will be connecting into headquarters to access resources. However, your boss is concerned with this. He does not understand how all of the users will be able to access the resources from HQ using only one link. In 1– 2 pages, explain the following to him:

• The technology that allows this to happen
• How this technology will allow the data request from multiple users to flow across a single link
To aid your explanation, use a Visio diagram (or similar software) of the layout of the two LANs to be connected by the WAN links.

SQL Server Management Studio

read and understand these pages:

Basic Project Requirements (Read This)
Week 2 – Keeping Data Separate from Analysis

Project Instructions:

When the assignment asks for analysis, description, or explanation – please put this in a separate MS Word (*.doc or *.docx) document and submit in addition to the main assignment file.

In order to complete this assignment, you will need to log into the virtual machine and use the Adventure Works database within SQL Server Management Studio.

For each question include:

the text version of the SQL script itself (in the Word Doc as mentioned above)
a screenshot of the SQL script in action (in the Word Doc as mentioned above)
Your screenshot should include both the query and the results
Make sure your screenshot includes the results from the GETDATE() function
Each script must include the GETDATE() (Links to an external site.)Links to an external site. function in the select statement
To keep the queries more straightforward, use aliases.

Section A

Create SQL Scripts that:

Selects ALL the BusinessEntityID, LastName, and FirstName fields for the Person’s table
Fields should be in the above order
Add a sort to the query so LastName is alphabetized A – Z
Add the person’s email address to Query #A1
Add the person’s phone number to Query #A2, include the PhoneNumberType Name field (etc. cell, home, work)
Add in the AddressLine1, City, StateProvinceID, and PostalCode fields to Query #A3
Note: two different people could have the same address. This database is designed to store each unique address individually, so SQL Server Management Studio while in this case this detail for this address would only exist once in the database, it would be assigned to all individuals with that address.
Note2: You will have to bring in two different Address tables to get this to portion to work.
Modify the Query from #A4 to include the StateProvinceCode, CountryRegionCode, and Name

Section B

Create a query that calculates a count of Departments by Group Name from the HumanResources.Department table.
Create a completely different query that shows the distinct listing of Product Subcatgories ( Production.ProductSubcategory), include ProductSubcategoryID and Name in the query
Modify the #B2 query to count the number of products from Production.Products by Subcategory, call the column “ProductCount”
Modify the #B3 query to include the Average StandardCost and the Average ListPrice, make sure to name the columns respectively. Order the results by the SubCategory Name (A-Z).
Add a column for the total product inventory quantity for each ProductSubcategory, make sure to name it as well.
Section C

Take your final query from #A5, modify the original query to filter out any people without an address, and load that query into Power BI.
You can copy and paste the SQL Statement in the Connection window (see below for connection details). This is the suggested (and easiest) approach.
Map those people by addresses in a Power BI visualization. Make sure the size of the bubble is indicative of the number of people in that city/state.
Are there any patterns or clusters that you can see in the mapped addresses? If so, what are a few of them?
Are there a significant number of people in the data set who live in countries outside of the US? If so, which continents include significant portions of people?
Use the best visualization that shows a count of people by state, show only those in the United States.
Take your final query from #B4 and load that query into Power BI. Create the best visualization(s) that shows each subcategory name, the price average and the cost average. Create a second visualization that shows the subcategory name and the product count. Do not simply create a table or matrix for these visuals.
Connection Information for Section C:

You will need the IP address of your Immersion lab (set up in week 5) and the username and password to accomplish Section C.

Remember to log into the Aloft Virtual Machine (VM) you need the following URL: https://maryville.okta.com/ (Links to an external site.)Links to an external site.

Once you are logged into the VM, you will need the following information to connect Power BI to SQL Server:

Your Immersion lab IP address
Database: AdventureWorks2016
The username and password are the default:
username: sa
password: pa55word
Make sure you have “Database” selected in your Authentication method in Power BI’s Access a SQL Server Database connection screen. Otherwise, the system won’t recognize your login.

Note: You cannot log into SQL Server from Power BI that may be installed on your computer. You can only connect to this instance of SQL Server from Power BI that is within the Virtual Machine
