  • Q12:To work on their projects, each student group (who sit in numbered tables, as described in HW1) can also (in addition to working at those numbered tables) reserve one of ten available rooms to work on their project. The rooms can be reserved for a block of a few hours (eg. 3 hours), with a start time and end time, eg. 3pm-6pm. 9am-2pm etc. At the end of the day, everyone goes home, so there's no possibility of rooms being booked for multiple days. The table structure you are asked to use, is this [you might need to change the syntax slightly, to make it work on your specific platform - same for other questions that follow]: CREATE TABLE ProjectRoomBookings (roomNum INTEGER NOT NULL, startTime INTEGER NOT NULL, endTime INTEGER NOT NULL, groupName CHAR(10) NOT NULL, PRIMARY KEY (roomNum, startTime)); There are two issues with the above. First, the start time could be incorrectly entered to be later than the end time. Second, a new entry (for a new group) could be accidentally put in to occupy a room, even before the existing group in that room is done using that room. For simplicity, you can express times in the 24h military-style format, eg. 9 for 9AM, 17 for 5PM, etc. For further simplicity, all bookings start and end 'on the hour', so, ints between 7 (7AM) and 18 (6PM) should be sufficient. How would you redesign the table to fix both these issues? For your answer, you can either provide a textual explanation, and/or provide SQL statements. Hint - "do not be concerned with efficiency" - ANY working solution is acceptable :) Another hint - no need to learn new techniques/syntax.See Answer
  • Q13:The owners decide to reward instructors with a bonus, at the end of the term. The bonus (a one-time payout) is calculated, like so: bonus = hourly_rate * sum_of_class_counts * 0.1 'sum_of_class_counts' is simply a total, of student count from each class an instructor taught - eg. if instructor Dat taught JavaScript, Python and Scratch, with enrollments of 20, 20 and 15 students respectively, the sum_of_class_counts for Dat will be 55 (if a student takes multiple courses - we count that student as many times, not count them as 1). Also, this bonus is just for teaching, not for supervising projects. Write a query that will output the highest bonus amount paid. Do feel free to create whatever table(s) you need, and populate it/them with your own data.See Answer
  • Q14:3. MENU RECOMMENDATION (Part 1: Meal Type) First create 4 records in the MC_90_DAYS_MEAL_TYPE table completing the INSERT statements below. You MUST assign a specific PK value to each record. However, all your queries MUST NOT assume those IDs in any circumstances. I will test your queries in my own data, and you will NOT know which MEAL_TYPE_ID I used to create each record, i.e., all filters and condition in queries MUST use the MEAL_TYPE_NAME column. INSERT INTO MC_90_DAYS_MEAL_TYPE (MEAL_TYPE_ID, MEAL_TYPE_NAME) VALUES ( 'Breakfast'); I INSERT INTO MC_90_DAYS_MEAL_TYPE (MEAL_TYPE_ID, MEAL_TYPE_NAME) VALUES ( 'Lunch '); INSERT INTO MC_90_DAYS_MEAL_TYPE (MEAL_TYPE_ID, MEAL_TYPE_NAME) VALUES ( 'Afternoon snack'); INSERT INTO MC_90_DAYS_MEAL_TYPE (MEAL_TYPE_ID, MEAL_TYPE_NAME) VALUES ( 'Dinner'); COMMIT; I I ISee Answer

  • Q17:PART 2: Smart Products / Services Definition: A smart product is an entity designed for self-organized embedding in the course of its lifecycle. A smart service generally implies a smart product and vice versa. For example, the Moroccan police department has introduced fixed radars which can be considered as a smart product. A smart service could be the website: (https://infractionsroutieres.narsa.gov.ma/InfractionsRoutieres/app/accueil) where citizens can check for their traffic violations. Think of an example of challenges that a business (new or existing one) might encounter and how to overcome them introducing a new service or product? Questions you may answer on your term paper: Why should companies build smart products and smart services? What benefits can the business gain? Provide several examples of new products or services you may introduce. What are some limitations of a smart products/services strategy? (A one-page paper might be sufficient for this essay)See Answer

  • Q19:Instructions 1. Building and Populating the Schema (9 marks) Develop a database in Oracle to implement the Erehwon Bank scenario. Code the SQL DDL to build all the tables, complete with constraints and default values (except for lookup of the Ref_Nbr for a Transaction... that will require procedural code in step 4). Choose appropriate data types for each of the columns. Add those indexes that you believe would be useful. Include comments in your SQL script(s) to document any decisions you made. Populate your database with the test data. • In your SQL INSERT statements, you must make use of sequences for generating key values for the Client, Account, and Transaction tables. • You must use the TO_DATE function to get proper date and time values for the transactions. Note that trigger code to be written in step 4 will be used to validate a Transaction Ref Nbr against either a Bank Nbr or Merchant Nbr as well as update the account balance according to the type and amount of the transaction. The test data already has entries for the Owns and Transaction INSERTS that should be rejected due to invalid FK lookups. Take a screen shot of running those scripts to show that is the case. It is not required to demonstrate NOT NULL constraints. 2. Views (4 marks) To facilitate queries, three views are required. Submit your SQL script(s) as well as a SELECT * FROM... listing of each view. Join of Transaction to Type description (1 mark) Join of Client to Account via the Owns table, containing the client's number, name, the account number, and balance. (1 mark) (Hint: Use an outer join as one client has no accounts.) • Join of Deposit and Withdraw transactions to Bank Branch UNION with join of Bill Payment and Debit Purchase, or Return transactions to Merchant (i.e., all transactions with appropriate reference name.)
