(Course mark - 17.5%)

You will work in groups of 3-4 members for this assignment. Register yourself on the Group registration link (under the Assignment section on the Stream site). Use the following set of steps to guide you in completing the assignment project. You should turn the work in for grading by the due date (Tuesday, 27th Aug 4.00 pm). Lateness: There is a 10% penalty / per day, and no submission is permitted after 3 days.

Note: Make sure you have altered the password of your allocated group Oracle a/c from the given default (GROUP01, GROUP02,…case sensitive). You do not want other people accessing your account. Remember it is your responsibility to protect your work. For the assignment, it is the joint responsibility of all the group members.

Logical and Physical Database Design

Read Te  Ohanga Village  -  Massey  University  Student  Accommodation  Office Case Study given in the Appendix A.

For Part A, complete the three steps (Step 1 – Step 3).

Part A: Step 1                                                                                                (30 marks)

Create a logical (relational) data model (e.g., Database or ER diagram). Use J Developer or Visio* to create this diagram. Use one of these two tools only.

Note*: Do not extract your diagram from SQL Developer  after creating tables or DataModeler (notation is different and some required modelling information to fully assess will be missing so cannot be graded fairly). Use of other tools (e.g. Generative AI tools), extractions from tools such as SQL Developer will all lead to a straight Zero.

Use appropriate naming conventions while naming tables, attributes, relationships, etc. in  your  diagram.  Also,  use  appropriate  attribute  datatypes,  data  sizes,  etc.  in  the  diagram and ensure to flag PKs, FKs, etc.

State the business rules very clearly (no ambiguity), consistently under a separate section (in your report). There should be two business rules for each relationship shown on your diagram (For example, if there are 10 relationships then there should be  10 pairs of rule  statements).  Similarly, state your reasonable assumptions (this helps us to evaluate your design better) under a separate section. The work presented in these two sections should be consistent with your ER diagram.

Examine  each  table’s  (entity's)  attributes  for  dependencies  and  apply  the  rules  of normalisation discussed in Chapter 6 of the textbook. You are required to show the detailed normalisation process  {e.g., how you move from lower normal form. (e.g., 1NF) to the next (e.g., 2NF)} in the submitted work. Use dependency diagrams for depicting all the relationships among a table’s attributes. Normalise tables up to the highest NF (up to 4th  NF should be fine). State the normal form. for each of the tables at every step in the process.

Part A: Step 2 (20  marks)

Generate the physical model based on the logical model created in the Step  1. To create the required set of tables, relationships, constraints, etc. write SQL scripts using a text editor (e.g., Notepad++). Use SQL Developer for initial checking / debugging and running of the code. Keep improving your code until you are satisfied with the design. Please ensure that it is consistent with your ERD (you may have to revise your ERD if you come up with better design during this stage).

Check the DDL code in your script. file and make sure that all the attribute definitions (e.g.,  names,  data  types,   data  sizes,  whether  required,   domain  values  including defaults, etc.), table constraints (e.g., entity integrity, referential integrity, etc.), etc. are specified adequately and correctly.

Validate your work by ensuring that query transactions  {(a) - (v) listed towards the end of the case study} are supported by your design. Make sure that the physical design   is robust i.e.,   meets  the  requirements   of  a   good   design.  Remember normalisation alone does not produce a good design. In the end, ensure that both logical and physical designs are consistent with each other.

Run your final scripts to generate the database (i.e., physical model). Use your Group Oracle a/c to implement the final DDL code.

Part A: Step 3 (10  marks)

Finally, create appropriate test data to populate the tables you created in Step2. Use SQL Developer to run a script. file that contains SQL INSERT statements.

There should be sufficient rows of the test data across all the tables. No table should contain less than five rows. Make sure your test data appropriately and sufficiently reflects your  design (this would usually mean adding more than  5 rows in some tables) and  does  not  violate  any  of the  constraints declared while creating the database design in Step1 and Step2 (i.e., create table scripts and the ERD). Set up all the tables and their constraints in the correct order before you load any data into the database. In  summary,  the  grader  should  be  able  to  verify  your  design convincingly, comprehensively and with ease.

Notes:

Apply good naming conventions, which are also self-explanatory (e.g., name create table script. file as createTables.sql, name your tables, attributes appropriately, etc.). Additionally, annotate your code (both DDL and DML) with appropriate and enough comments to enhance understandability. Consistency between work done in all the steps is very important otherwise you will unnecessarily risk losing a good number of marks for this reason.

Check your project work and make sure that all the scripts run without any errors. Also, ensure that appropriate names have been given to all files.

This assignment is also testing only your basic SQL knowledge, so write code for all the DDL and DML statements. Do not give us automated statements that are derived from Oracle tools (i.e., SQL Developer or JDeveloper). No marks will be allocated for DDL/DML scripts generated by Oracle tools. The code should NOT be tied to the schema, and we should be able to run the code from any Oracle account.

Assignment Submission

Organise your project report (printer-friendly, in case we need to print – grader’s preference) to include all the assignment requirements. Make sure the report contents are also in the same order as the laid requirements.

There are three parts to this assignment submission:

•   a project report (word/pdf – soft copy),

• scripts (2 code files – sets of create and insert statements),

• database (tables, etc under your Group account).

Note:

Enter  your  names,   student  ids   on  the  project  marking  sheet (Appendix B). Remember to provide the (Group) Oracle username in your report. The Password not needed.

Checklist for project report (word/pdf) contents

1.   A logical relational model (database or ER diagram) that is laid out clearly and legibly for grading. The text font size should not be very small (otherwise risk  getting  a  straight  zero)*. The  diagram  should  show  all  the  entities, attributes (with appropriate data types, sizes, etc.), primary keys, foreign keys, and relationship details (appropriate association names, cardinality, strength (identifying or non-identifying), participation (mandatory or optional)),  etc. Make sure you have applied and shown the normalisation process to arrive at the final model. Pay special attention to the readability of the ER diagram so that one could print and assess with ease (as this is the core of all the work).

2.   A discussion of the reasonable assumptions you make about the ambiguous aspects and / or reasonable extensions to the given case study. We anticipate that each group's design will differ** from those of other groups based on the underlying assumptions.

3.   A list of business rules for each relationship on your diagram (clearly state two unambiguous rules for each relationship as these are bi-directional).

4. DDL and DML code that is taken from the command files used for creating (create statements) and populating (Insert statements) your Oracle tables.

This  should  NOT  be  auto  generated  code  and/or  linked  to  your  schema account. Remember to include declarative constraints, etc in Create table code. Do not provide Alter statement  code  separate to the  Create  statements  i.e.

place all the constraints next to the attributes where possible. Basically, use only one single statement to create a table.

5. Test Data (well formatted, readable dump of contents for all the tables) that can be referred to with ease. This helps in evaluating the design.

Checklist for submission under your Group Oracle a/c

All the tables with test data must be available via your Group Oracle a/c.

Checklist for submission on Stream

Compressed Folder – containing Report (a word/pdf file) and coding files (2 .sql files). Include your IDs in the name of your compressed file.

Submit on the Assignment (Part A) link. Only one single submission per group. Plagiarism and other project guidelines:

* If your diagram elements are too small then a ZERO mark would be awarded. In addition,  ensure  that the layout  of your  diagram  is  good  (e.g.,  avoid many  criss- crosses, etc.) and the font size of the entities, attributes etc. is at least Arial  11 (or similar size if using a different font family, style). Make your diagram easy to read for the grader. You might want to use print settings for ERD with multiple (A4) pages or format diagram as per A3 size. Please put in effort to make it presentable and readable or risk losing marks.

Use of any AI tools is NOT Permitted for the course assessments. You can find more information about the Student Academic Integrity Policy here. This will lead to a ZERO and may lead to an academic investigation by the Academic lead.

We suggest you keep a record of the intermediate work (work in progress) leading up  to your assignment submission as you may be asked to establish that this is your work and is done over a period of time.

**A ZERO mark will be given to ALL the collaborating parties (no discussion on

who did the original work and who copied). Any partial copying will also be awarded a straight ZERO.

Make  sure  all  your  work  is  complete  before  you   submit.  Graders  will not be searching/chasing you for any not easily traceable/missing assignment components.

Not adhering to any of the assignment requirements, may also be given a straight

ZERO.

Note: Turnaround time for assignment may be slightly over the usual three weeks.

Appendix A

Te Ohanga Village, Albany - Massey University Student

Accommodation Office Case Study

The   Director   of Te    Ohanga    Village,   Albany   -   Massey    University    Student Accommodation   Office requires  you  to   design  a  database  to  assist  with  the administration of their accommodation office. After involving various stakeholders, the requirements collection and analysis phase of the database design process has provided the following requirements for the Student Accommodation Office database. These requirements are followed by examples of the query transactions that must all be supported by the database design.

1.   The data stored on each full-time student must include student details such as the identification number, name, home address, age, gender, category of student (e.g., undergraduate, postgraduate), nationality, smoker/non-smoker, special needs, any additional  comments,  status  (e.g., placed/waiting),  and  what  degree course the student is studying towards, etc. Accommodation is available for students with accessibility requirements, but these must be recorded in the system.

The student information stored relates to those currently renting some form. of accommodation and those on the waiting list. Students may rent a room in a hall of residence or a student flat (4-5 bedrooms apartments). Post-graduate, mature students may in addition opt for renting studio units.

When a student joins the university, he or she is assigned to a staff member who acts as his or her Advisor (of studies). The Advisor is responsible for monitoring the student's welfare and overall academic progress. The data held for a student's Advisor  includes their name, position, name  of department,  internal telephone number, room number, etc.

2.   Each hall of residence has a name (e.g., Tui, Pukeko, Weka), address, telephone number, and a hall manager who supervises the operations of the hall. The halls provide  only  single  rooms,  which  have  a  room  number,  place  number,  and monthly rent rate. These have shared, private bathrooms and communal areas on each floor. Currently, each of the three halls can accommodate up to 70 students. Halls  of  residence  offer  fully  catered  services  (2  meals  per  day)  but  can accommodate to various dietary requirements.

The place number uniquely identifies each room in all the halls controlled by the student accommodation office and is used when renting a room to a student.

3.   The accommodation office also offers student flats. These flats are fully furnished and provide single room accommodation for groups of four to five students. They have common areas that flat members share. The information held on student flats includes a flat number, address, and the number of single bedrooms available in each  flat.  The  flat number uniquely  identifies  each  flat.  Flats are  self-catered. Currently there are 70 flats.

Each bedroom in a flat has a monthly rent rate (this can occasionally very based on  the  room  area),  a  room  number,  and  a  place  number.  The  place  number uniquely  identifies  each  room  available  in  all  student  flats  and  is  used  when renting a room to a student.

4.   The  studio  units  offered  by  the  accommodation  office  allow  only  for  single occupancy (i.e., cannot be shared by the students). Mature students with small families usually rent these units (e.g., they can have a partner and/or a child living with them). The number of members residing in a unit needs to be recorded along with some essential details about each of the members (name, age, etc).

Each studio unit has a monthly rent rate, and a unique studio unit number. In addition,  studio  units  have  the  fully  or  partly  furnished  options  but  are  self- catered. Currently there are 12 units.

5.   A student may rent a room (in a hall or student flat) or a studio unit for various periods. They need to sign a rent lease agreement before they can move in.

New lease agreements are negotiated at the start of each academic year with a minimum rental period of one year, which includes semesters 1, 2 and the summer semester.   Each    individual   lease    agreement    between   a    student    and   the accommodation office is required to be unique.

The  data  stored  on  each  lease  includes  the  duration  of  the  lease  (given  as semesters), student details, place number, room number, address details of the hall / student flat / studio, the date the student wishes to enter the room, and the date the student wishes to leave the room (if known), etc.

6.   At the start of each semester, each student is sent an invoice for the ensuing rental period. Each invoice has a unique invoice number.

The  data  stored  on  each  invoice  includes  the  invoice  number,  lease  number, semester, payment due, student’s ID number and full name, place number, room number, and the address of the hall or flat. Additional data is also held on the payment of the invoice and includes the date the invoice was paid, the method of payment  (e.g.,  cheque,  cash,  etc.),  and  the  date  the  first  or  second  payment reminder is sent (if necessary), etc.

7.   Staff on a regular basis inspect  student flats and studio units to ensure that the accommodation is well maintained. The information recorded for each inspection is the name of the member of staff who carried out the inspection, the date of inspection, an indication of whether the property was found to be in a satisfactory condition or not, any additional comments, etc.

8.   Some information is also held on members of staff of the accommodation office and includes the staff number, home address,  sex, position (e.g., Hall Manager, Administrative  Assistant,  Cleaner,  etc.),  location  (e.g.,  accommodation  office, Hall), etc.

9.   The accommodation office also stores a limited information on the degree courses run by the University such as degree title, degree director name, internal telephone number, and room number, department name, etc. Each student is associated with a single degree course.

10. Information  on  a  student's  next-of-kin  is  stored  which  includes  the  name, relationship, contact details, etc. This information disclosure is not mandatory.

Query Transactions

The following transactions must be supported by your database design. However, you are NOT required to implement these transactions (in Part B you will write code so there is no need to write the SQL code for these queries). Use the following only to validate your database design using a dry run. All the attributes are spelled out in the description above but may be part of the transactions listed below.

a)   Create a suburb-wise staff list (based on their residential address).

b)  Create a list of students and staff who have their birthday next month.

c)   Create a list of post-graduate students who live in studio units.

d)  Create  a  report  listing  halls  of  residence  Manager’s  name  and  telephone number.

l)   Display the total number of students in each student category.

m) Create a report listing the names and ID numbers for all students who have not supplied details of their next-of-kin.

n)  Display the minimum, maximum, and average monthly rent for rooms in halls of residence.

o)  Create a report listing students who have opted for Vegetarian or Vegan as their catering option. In the report include their hall of residence as well.

p)  Display the total number of rooms currently occupied and total number of places available in each hall of residence.

q)  Display the staff number, name, age, and current location of the staff who have been working 5 years or more at the accommodation village.
