Answer the following questions (please copy the question’s text before each of your answers) and submit them to your professor for grading.  1. Assume that at Pine Valley Furniture products are composed of components, products are assigned to salespersons, and components are produced by vendors. Also assume that in the relation PRODUCT (Prodname, Salesperson, Compname, Vendor), Vendor is functionally dependent on Compname and Compname is functionally dependent on Prodname. Eliminate the transitive dependency in this relation and form 3NF (third normal form) relations. 2. Transform the E-R diagram of Figure 8-3 into a set of 3NF relations. Make up a primary key and one or more non-keys for each entity. 3. Transform the E-R diagram of Figure 9-21 into a set of 3NF relations. 4. Consider the list of individual 3NF relations below. These relations were developed from several separate normalization activities. PATIENT(Patient_ID, Room_Number, Admit_Date, Address) ROOM(Room_Number, Phone, Daily_Rate) PATIENT(Patient_Number, Treatment_Description, Address) TREATMENT(Treatment_ID, Description, Cost) PHYSICIAN(Physician_ID, Name, Department) PHYSICIAN(Physician_ID, Name, Supervisor_ID) (a) Merge these relations into a consolidated set of 3NF relations. State whatever assumptions you consider necessary to resolve any potential problems you identify in the merging process. (b) Draw an E-R diagram for your answer to part “a”. 5. Consider the following 3NF relations about a sorority or fraternity: MEMBER(Member_ID, Name, Address, Dues_Owed) OFFICE(Office_Name, Officer_ID, Term_Start_Date, Budget) EXPENSE(Ledger_Number, Office_Name, Expense_Date, Amt_Owed) PAYMENT(Check_Number, Expense_Ledger_Number, Amt_Paid) RECEIPT(Member_ID, Receipt_Date, Dues_Received) COMMITTEE(Committee_ID, Officer_in_Charge) WORKERS(Committee_ID, Member_ID) (a) Foreign keys are not indicated in these relations. Decide which attributes are foreign keys and justify your decisions. (b) Draw an E-R diagram for these relations, using your answer to part “a”. (c) Explain the assumptions you made about cardinalities in your answer to part “b”. Explain why it is said that the E-R data model is more expressive or more semantically rich than the relational data model. 6. Consider the following functional dependencies: Applicant_ID --> Applicant_Name Applicant_ID --> Applicant_Address Position_ID --> Position_Title Position_ID --> Date_Position_Opens Position_ID --> Department Applicant_ID + Position_ID --> Date_Applied Applicant_ID + Position_ID + Date_Interviewed --> (Nothing) (a) Represent these attributes with 3NF relations. Provide meaningful relation names. (b) Represent these attributes using an E-R diagram. Provide meaningful entity and relationship names. 7. Suppose you were designing a file of student records for your university’s placement office. One of the fields that would likely be in this file is the student’s major. Develop a coding scheme for this field that achieves the objectives outlined in Chapter 10 for field coding. 8. Suppose you created a file for each relation in your answer to question “3” above. If the following queries represented the complete set of accesses to this database, suggest and justify what primary and secondary key indices you would build. (a) For each PART in Item_Number order list in Vendor_ID, sequence all the vendors and their associated prices for that part. (b) List all PART RECEIPTs, including related PART fields for all the parts received on a particular day. (c) For a particular VENDOR, list all the PARTs and their associated prices that VENDOR can supply.

how would I write these functions recursively in c++int account::findAccount(int acctNumber, account accts[MAX], int count){for (int i = 0; i < count; i++){if (accts[i].acctNumber == acctNumber)return i;}return -1;}And this function as wellvoid account::displayAll(account accts[MAX], int count){for (int i = 0; i < count; i++){accts[i].displayAccount();cout << endl;}}

Answer the following questions (please copy the question’s text before each of your answers) and submit them to your professor for grading. 1. Consider software applications that you regularly use that have menu interfaces, whether they be PC- or mainframe-based applications. Evaluate these applications in terms of the menu design guidelines outlined in Table 11-1 of our textbook.2. Consider the possible design of a registration system for a hotel aimed at front-desk hotel employees. Following the design specification items in Fig. 11-2, briefly describe the relevant users, tasks, and displays involved in such a system.3. Imagine the possible design of a system used to register students at a university. Discuss the user, task, system, and environmental characteristics (see Table 10-10 of our textbook) that should be considered when designing the interface for such a system.4. For the three common methods of system interaction --command language, menus, and objects-- recall a software package that you have used recently and list what you liked and disliked about the package with regards to the interface. What were the strengths and weaknesses of each interaction method for this particular program? Which type of interaction do you prefer for which circumstances? Which type do you believe will become most prevalent? Why?5. Briefly describe three or more different business tasks that are good candidates for form-based interaction within an information system.6. Propose three or more specific settings where natural language interaction would be particularly useful and explain why.7. Examine the help systems for three or more software applications that you use. Evaluate each using the general guidelines provided in Table 12-11 of our textbook.8. List four contributing factors that have acted to impede the design of high-quality interfaces and dialogues on Internet-based applications.
