    M359 Relational databases: theory and practice TMA Fall 2013-2014 Cut-off date: 11, December 2013 Question 1 10 MarksBriefly describe the term “Cloud Database”. Your answer should include definition, different methods to run cloud database, benefits and examples of cloud database services. You need to check your e-library or external resources to provide an adequate answer to this question. Zero mark will be awarded for the answers without proper referencing. Question 2 20 MarksThis question assesses your understanding of the Conceptual Data Model (CDM) presented in section 5 of Block 1. Give a conceptual data model (CDM) for the following given scenario using the Entity-Relationship model, including the complete E-R diagram, the entity types and any required constraints and assumptions. A social recreation club would like to create a database to keep track of club members, committees and activities. Suppose that after requirements collection and the analysis phase the database designers provide the following descriptions to be represented in the database.The club forms committees for different activities. Committee is formed by several members. Each committee has a unique name, a unique number, and a particular member who manages the committee. The system keeps track of the start date when that member began managing the committee. A committee controls a number of activities, each of which has a unique name, a unique number and description of the event. A committee may organize activities for several events. The database stores the member’s unique identification number, member name, address, gender and birth date. A member is assigned to one committee, but may participate on several activities, which are not necessarily controlled by the same committee. The system keeps track of the direct head of team members (who is another member). For payment purpose the system also keeps track of details of non-club members participating in the activities, in special circumstances. Their details to be stored in the system are artist’s first name, gender, birth date and the club member who recommended them to the club. Question 3 20 MarksThis question assesses your understanding of E-R conceptual modeling as discussed in Section 5 of Block 1 and assesses your knowledge of Block 2, Sections 2 and 4, and in particular, your understanding of the relational representations.

              Question 1
              Briefly describe the term “Cloud Database”. Your answer should include definition, different methods to run cloud database, benefits and examples of cloud database services. You need to check your e-library or external resources to provide an adequate answer to this question. Zero mark will be awarded for the answers without proper referencing.
              Question 2
              This question assesses your understanding of the Conceptual Data Model (CDM) presented in section 5 of Block 1.
              Give a conceptual data model (CDM) for the following given scenario using the Entity-Relationship model, including the complete E-R diagram, the entity types and any required constraints and assumptions.

              A social recreation club would like to create a database to keep track of club members, committees and activities. Suppose that after requirements collection and the analysis phase the database designers provide the following descriptions to be represented in the database.
              The club forms committees for different activities. Committee is formed by several members. Each committee has a unique name, a unique number, and a particular member who manages the committee. The system keeps track of the start date when that member began managing the committee. A committee controls a number of activities, each of which has a unique name, a unique number and description of the event. A committee may organize activities for several events. The database stores the member’s unique identification number, member name, address, gender and birth date. A member is assigned to one committee, but may participate on several activities, which are not necessarily controlled by the same committee. The system keeps track of the direct head of team members (who is another member). For payment purpose the system also keeps track of details of non-club members participating in the activities, in special circumstances. Their details to be stored in the system are artist’s first name, gender, birth date and the club member who recommended them to the club.
              Question 3
              This question assesses your understanding of E-R conceptual modeling as discussed in Section 5 of Block 1 and assesses your knowledge of Block 2, Sections 2 and 4, and in particular, your understanding of the relational representations. Questions a and b assess your ability to transform a simple E-R fragment into a corresponding relational representation and questions c and d assess your ability to transform relational representation into corresponding E-R fragment
              a. Convert the following E-R fragment into a relational representation.

                T324: Keeping ahead in ICTs
                Tutor-Marked Assignment, Fall 2013 2014




                Q1. Investigating socio-technical system
                You have studied in block three of the course materials the socio-technical system approach for investigating system failures. To demonstrate your understanding of this part of the course, answer to the following questions:
                1. Select a socio-technical system that you use in your daily life.
                2. Draw the system map that you think representative for the selected system.
                3. Present briefly two processes of the selected system.
                4. Discuss the major criteria of failure of such system.
                5. From your point of view, what is the major reason(s) that may lead such system to failure?
                6. Based on your answer in the previous part, which system questions can be regarded as counterparts to these?


                7. Explain briefly how investigating the system questions of the previous part could help in avoiding failure or identifying its reasons.


                Q2. Innovation in IEEE 802.11
                IEEE 802.11ac is the fifth generation of WiFi which is faster and more scalable version of 802.11n. IEEE 802.11ac couples the freedom of wireless with the capabilities of Gigabit Ethernet. Using the AOU e-library and Internet resources, you are asked to write an essay presenting an overview on the standard IEEE 802.11ac while providing its major physical layer specifications (e.g., throughput, RF bandwidth, channel bonding, number of MIMO spatial streams, modulation technique). Your essay should contain at least 500 words and the list of references. It should not include unapproved websites as Wikipedia or like citation. Marks will be deducted in case of essay lacking reliable references or containing errors in syntax, structure, and style.


                Q3. Sniffing wireless traffic using Wireshark
                Wireshark is the world’s most popular network protocol analyzer. It is used for troubleshooting, analysis, development and education. The software and its user guide could be downloaded from its home page (i.e., Wireshark آ· Go Deep.). In this question, you will investigate the 802.11 wireless network protocol using this passive measurement tool. For more information on 802.11 management frame types, you can find many references as for example “Understanding 802.11 Frame Types” by Jim Geier (i.e., Understanding 802.11 Frame Types).


                Unfortunately, most of the device drivers for wireless 802.11 NICs (particularly for Windows operating systems) don’t provide the hooks to capture/copy received 802.11 frames for use in Wireshark. Therefore, we will provide you in this question a trace of captured 802.11 frames to analyze; assume in the following questions that you are using this trace. If you are able to capture 802.11 frames using your hardware settings, we encourage you to train on this software using your proper tests. An alternative solution for packet capture that you can use in your upcoming projects is to use a small USB device, AirPcap, (i.e., Riverbed آ· CACE is now part of Riverbed Technology) that captures 802.11 frames and provides integrated support for Wireshark under Windows.


                To start the experiment, open in Wireshark the trace Wireshark_802_11.pcap which is attached to the TMA files. You can load the trace into Wireshark using the File pull down menu, choosing Open, and then selecting the Wireshark_802_11.pcap trace file. The resulting display should look just like Figure 1.





                Figure 1: Wireshark window, after opening the Wireshark_802_11.pcap file


                For answering the following questions, you should look at the details of the IEEE 802.11 frame and subfields in the middle Wireshark window.




                To deal with the plagiarized answers in this question, the student must make an oral demo of the software for his/her tutor showing him/her how he/she has opened the trace and manipulated the packets to find the answers provided in the submitted TMA. Then, tutor can decide to deduct (or not) part or whole of the marks awarded based on the quality of the demo.
                1. Given that beacon frames are used by an 802.11 AP to advertise its existence. What are the SSIDs of the two access points that are issuing most of the beacon frames in this trace?


                2. What are the intervals of time between the transmission of the beacon frames from the
                linksys_ses_24086 access point? From the 30 Munroe St. access point? (Hint: this interval of time is contained in the beacon frame itself).


                3. What (in hexadecimal notation) is the source MAC address on the beacon frame from 30 Munroe St?


                4. What (in hexadecimal notation) is the destination MAC address on the beacon frame from 30 Munroe St?


                5. What is the BSS ID of 30 Munroe St?


                6. The beacon frames from the 30 Munroe St access point advertise that the access point can support four data rates and eight additional “extended supported rates.” What are these rates?


                7. What is the Channel number used for WiFi communication?


                8. Consider the first PROBE REQUEST and the soonest subsequent PROBE RESPONSE PAIR occurs after t = 2.0 seconds in the trace. When these frames sent and what are the sender, receiver and BSS ID MAC addresses for these frames? What is the purpose of these two types of frames?
