ITC556 - Database Systems Session 2 2019 Faculty of Business, Justice and Behavioural Sciences School of Computing and Mathematics Charles Sturt University
This subject will provide a solid grounding in database design . It will show the importance of database design in the development of applications that meet business needs. There will be an emphasis on modeling a database using Entity Relationship Diagrams (ERDs), optimising its design using normalisation techniques and implementing it and querying it using Structured Query Language (SQL).
Upon successful completion of this subject, students should:

HW does not carry any stock. A few spas are set up in a simple warehouse so customers can see some of the models available, but any products sold must be ordered at the time of the sale.
Create an ERD for each of the above statements that describe the current business rules for HW. For each new statement being the business rule.

You are encouraged to complete this subject's sample exam (https://doms.csu.edu.au/csu/ file/08754316-08a6-4646-a27c-a5fe5b6ab4cd/1/ITC556-DatabaseSystems-

Academic integrity means acting with honesty, fairness and responsibility, and involves observing and maintaining ethical standards in all aspects of academic work. This subject assumes that you understand what constitutes plagiarism, cheating and collusion. If you are a new student we expect you to complete the modules called Academic Integrity at CSU (http://student.csu.edu.au/library/integrity/academic-integrity-course).
CSU treats plagiarism seriously. We may use Turnitin to check your submitted work for plagiarism. You can use Turnitin to check for plagiarism (http://student.csu.edu.au/library/ integrity/referencing-at-csu/checking) in your assessments before submission.
Referencing is an important component of academic work. All assessment tasks should be appropriately referenced. The specific details of the referencing requirements are included in each assessment task description. Get referencing style guides and help
(http://student.csu.edu.au/library/integrity/referencing-at-csu) to use for your assessments.
Assessment items that are completed within the Interact 2 site, such as quizzes, tests and self and peer assessments in the blog and wiki are noted in the assessment section above. You need to complete these tasks within your subject site.
Assessment tasks that are NOT completed through the Subject site need to be submitted electronically via Turnitin site by the due date. Turnitin class details for this subject will be given by your lecturer.
Unless advised otherwise, all Turnitin submissions are due by midnight (AEST) of the date specified. Please note that the time and the date of your Turnitin submission will be used to determine your official submission time.
All textual elements within an assessment must be submitted in a format that is readable by Turnitin. Specific exceptions, where an assessment requires the insertion of image-based evidence of workings will be outlined in the context of the assessment. Students that deliberately attempt to insert the content of assessments in a format that is not readable by Turnitin may be subject to Academic misconduct investigations.
Additional Submission Information:
It is recommended that your name, student ID and page number are included in the header or footer of every page of any assignment. You are also required to rename your assignment file before you submit via Turnitin as per below protocol:
SUBJECT CODE, SI, SURNAME, STUDENT ID, ASSESSMENT NUMBER, SESSION.
Example – ITC561 SI PATEL 11554466 A1 201960.doc
Under normal circumstances postal submissions will not be accepted for any of the assessments required.
Under normal circumstances hand delivered submissions will not be accepted for any of the assessments required.
Alternative submission process See online submission above.
It is best to complete assessment items by the due date. However, when something unavoidable comes up an extension may be possible. The following principles are used when processing extensions:
https://apps.csu.edu.au/specialcons/. This request must be made within 3 working days of the date of exam and must include supporting documentation. Acceptable reasons are given in the Special Consideration Policy <https://policy.csu.edu.au/view.current.php?id=00298>. For medical issues, a CSU medical certificate is required. If the supplementary exam (SX) is awarded then your exam is moved to the next examination period. In order to preserve exam integrity and manage the logistics of exams, the timing of a supplementary exam
Academic regulations provide for special consideration to be given if you suffer misadventure or extenuating circumstances during the session (including the examination period) which prevents you from meeting acceptable standards or deadlines. Find the form on the Student Portal Special Consideration, Misadventure, Advice and Appeals (http://student.csu.edu.au/ study/academic-advice) page. Penalties for late submission
The penalty for late submission of an assessment task (without obtaining the Subject Coordinator's approval for an extension) will be:
10% deduction per day, including weekends, of the maximum marks allocated for the assessment task, i.e. 1 day late 10% deduction, or 2 days late 20% deduction.
An example of the calculation would be:
Maximum marks allocated = 20
Penalty for one day late = 2 marks (so, a score of 18/20 becomes 16/20 and a score of 12/20 becomes 10/20).
If an assignment is due on a Friday but is not submitted until the following Tuesday, then the penalty will be four days (40% deduction or 8 marks in the example above).
Submissions more than 10 days late will be acknowledged as received but will not be marked.
Under normal circumstances resubmission of assessment items will not be accepted for any of the assessments required in this subject.
Feedback processes
Feedback for assessment items will be provided by subject lecturer/s.
You should normally expect your marked assignment to be returned to you within 15 working days of the due date. If you submitted your assignment on time but have not returned by the return date, you should make enquiries in the first instance to the subject lecturer. If the subject lecturer is not available then contact your Course Coordinator on Level 4, 30 Church Lane.
CSU values constructive feedback and relies on high response rates to Subject Experience
Surveys (SES) to enhance teaching. Responses are fed back anonymously to Subject
Coordinators and Heads of Schools to form the basis for subject enhancement and recognition of excellence in teaching. Schools report on their evaluation data; highlighting good practice and documenting how problems have been addressed. You can view a summary of survey results via the Student Portal SES Results (https://student.csu.edu.au/study/subjectexperience-survey-results) page.
We strongly encourage you to complete your online Subject Experience Surveys. You will be provided with links to your surveys via email when they open three [3] weeks before the end of
session.
This subject has been developed over several years and we have included the feedback from students in previous years when preparing this subject. In particular, this year the subject has been changed in response to feedback from last year’s class in the following ways:
Learning Analytics refers to the collection and analysis of student data for the purpose of improving learning and teaching. It enables the University to personalise the support we provide our students. All Learning Analytics activities will take place in accordance with the CSU Learning Analytics Code of Practice. For more information, please visit CSU's Learning Analytics (http://www.csu.edu.au/division/student-learning/home/analytics-and-evaluations/ learning-analytics) website.
Data about your activity in the Interact2 site and other learning technologies for this subject will be recorded and can be reviewed by teaching staff to inform their communication, support and teaching practices.
