Database – Discussions

Create a discussion thread (with your name) and answer the following question(s):

Discussion 1 (Chapter 13): What are the differences between structured, semistructured, and unstructured data?

Instructions:  Your response to the initial question should be 250-300 words.  Next respond to two postings provided by your classmates. The first post should be made by Wednesday 11:59 p.m., EST. I am looking for active engagement in the discussion.  Please engage early and often. You are require to create your initial thread in order to view and respond to the threads posted by other students.  There must be at least one APA formatted reference (and APA in-text citation) to support the thoughts in the post as needed.  Do not use direct quotes, rather rephrase the author’s words and continue to use in-text citations.

Review the contributions and determine if they have any gaps in their understanding of what happens at each layer.. 50-75 words

 

 As we deep dive into TCP/IP and OSI protocols, looking at each one’s  architecture.  TCP/IP consists of four to five layers application,  transport, network, data link, and physical. OSI (International  Organization for Standardization) consists of seven layers application,  presentation, session, transport, network, data link, and physical.   

     Both Protocols use application for their first layers.  The  application layer supports applications and sometimes support services  such as encryption and compression.  Which user applications like  browser and word processing applications are not found within this layer  they use protocols that function within the application layer.   Application Protocols used for TCP/IP and OSI include HTTP (Hypertext  Transfer Protocol) which allows browsers and servers to send and receive  web pages.  SMTP (Simple Mail Transfer Protocol) enables users to send  and receive emails.  FTP (File Transfer Protocol) moves files from one  computer to another.  SSH (Secure Shell) allows remote computers to  securely log in to other computer systems.  SNMP (simple Network  Management Protocol) manages the numerous elements in a computer network  to be managed at a single point. 

     Looking at the second layer of TCP/IP and OSI which they differ.    TCP/IP second layer is the Transport Layer.  Which uses TCP  (Transmission Control Protocol) this allows for an error free end to end  connection.  TCP protocol is not the only protocol found in the  Transport Layer.  You can also find UDP (User Datagram Protocol) this is  not commonly found within this layer and usually used when steaming  data like music or videos.  OSI uses the presentation layer for its  second layer.  We do not find this layer within TCP/IP.  Which it  performs functions for presenting data properly to the sender or  receiver.

     The Third layer of TCP/IP and OSI differ also.  TCP/IP has the  Network layer thirdly.  The Network layer also known as Internet layer  or IP layer is used to transfer data within, and between networks.  IP  (Internet Protocol) software which prepares packets of data for  transmission between the networks. OSI third layer consists of the  session layer and is not found within the layering of TCP/IP protocol.   The session layer consists of transferring large amounts back and forth  between two systems.  It uses a point after each small section of  transmission to ensure proper data transmission.

     Now we are at the fourth layer of TCP/IP and OSI protocols.   TCP/IP uses Data Link at this layer.  Data Link layer which gets data  from user’s workstations and passes it to the router connected to the  Internet.  Commonly the LAN gets the data from workstation to Internet.   The Data Link Layer prepares data for transmission to a router sitting  between the LAN and internet.  OSI’s fourth layer is the second layer of  TCP/IP, Transport Layer.  Which verifies the data that arrived at the  destination is the same sent from the original station.

     Diving into the fifth layer of TCP/IP and OSI we see they also  differ.  With TCP/IP we find the Physical Layer which is the final layer  of its architecture.  This is where the data transmission occurs.  This  can be through physical wiring, or radio signal.  OSI uses the same  layer TCP/IP uses at its third layer.  Network layer also known as  Internet layer or IP layer is used to transfer data within, and between  networks.  IP (Internet Protocol) software which prepares packets of  data for transmission between the networks.

     OSI architecture only contains two more layers which are  included in the architecture of TCP/IP.  The sixth layer of OSI is the  Data Link layer it prepares data for transmission to a router sitting  between the LAN and internet.  OSI’s fourth layer is the second layer of  TCP/IP, Transport Layer.  Which verifies the data that arrived at the  destination is the same sent from the original station.  The seventh  layer is the Physical layer which is the final layer of OSI  architecture.  The physical layer where the data transmission occurs.   This can be through physical wiring, or radio signal.  

     After deep diving into both TCP/IP and OSI protocols we can see  that OSI architecture is bigger and more in depth then TCP/IP.   Understanding their architecture really brings why and what purpose  would you want to use ether.  My opinion is that you would use OSI in a  more secured networked area and TCP/IP within a expansion and smaller  less secure networked area.

Discussion 3- Planning

Chapter 7: Project InitiationChapter 8: Overview of Project PlanningInitial Postings: Read and reflect on the assigned readings for the week. Then post what you thought was the most important concept(s), method(s), term(s), and/or any other thing that you felt was worthy of your understanding in each assigned textbook chapter.Your initial post should be based upon the assigned reading for the week, so the textbook should be a source listed in your reference section and cited within the body of the text. Other sources are not required but feel free to use them if they aid in your discussion.Also, provide a graduate-level response to each of the following questions:

  1.  Your manager recently gave you the responsibility of selecting the next project, which you will manage as the project manager.  There are currently 3 projects on hold to choose from.  Using the weighted scoring models method, you determine that Project A has a weighted score of 16, Project B has a weighted score of 14, and Project C has a weighted score of 17.  Which project do you choose and why?

Canvas Cloud Architecture Security Risks

 

Introduction

O’Keefe State University located in New Mexico has recently started using Canvas for online course delivery. Canvas hosts all the data in its own cloud storage. Students may log in to the systems form any personal device (laptops, phones, etc.). On-campus students can also use library computers. Note that the browsers may store student credentials (IDs and passwords) in a browser.

Directions 

Write a two-page security risk analysis to identify all possible security risks associated with the usage of Canvas in the library or on home computers.

Specifically address whether Canvas cloud architecture increases or decreases the cybersecurity risks associated with it, when compared to an old learning system that stored all student data on a servers located on-campus and managed by the university IT personnel.
