Course Description

This unit defines the competency required to understand business operations, identify entities and data, diagrammatically represent their relationships and prepare a data model

If you are undertaking this course in Melbourne from semester 2, 2012 onwards your teacher will advise you if you require access to a computer for the course. It is recommended that you have access to a mobile computing device to allow greater flexibility in terms of where you can work on campus outside class times.

Overview of Assessment

Assessment may incorporate a variety of methods including technical requirements documentation, homework, assignments, group and/or individual projects and in class exercises, written tests, practical problem solving exercises, presentations, practical tests and a final exam. Students are advised that they are likely to be asked to personally demonstrate their assessment work to their teacher to ensure that the relevant competency standards are being met.

Students will be provided with feedback throughout the course to check their progress.

 


Assessment Tasks

Assessment 1 (Worksheets): 30%

The purpose of these worksheets is to provide feedback to students about their learning and observe them doing the required course material in the class. Therefore students will gain an understanding of the steps involved in solving database design problems, which includes functional dependencies, normalisation, ERD and ERD mapping for implementation, validating the model and documentation. Printouts (or electronic copy in Drop box) are to be submitted during class. Unfortunately, it will not be possible to accept late submissions or e-mail submissions.

Assessment 2 (Project): 35%


The purpose of this project is to ensure that students are able to implement all the skills they have developed to date.

A case study or real life project is defined and made available to students in Week 2. The students will be required to submit as a project assignment in two stages (Refer weekly breakdown). During this period each student is given feed back on their project for further improvement in their model mimicking the industry approach to a design problem

Assessment 3 (Test): 35%

A final examination will be offered to students who have achieved CA.

Other Information

Competency and Grading Requirements:

To be deemed competent students must demonstrate an understanding of all elements of a competency. Assessment methods have been designed to measure achievement of each competency in a flexible manner over multiple tasks. Students are advised that they are likely to be asked to personally demonstrate their assessment work to their teacher to ensure that the relevant competency standards are being met.

All assessments for this course must be completed to achieve a CA (Competency Achieved) grade.

Each assessment task will also carry a numerical weighting to be used for grading purposes. The grade applied to this weighting will only be awarded if a CA has been achieved in all compulsory assessment tasks.

If a student has been marked NYC (Not Yet Competent) in any of the assessment tasks, the weighting will carry no value until the student has obtained a CA.
If a CA is achieved on re-assessment then a maximum mark of 50% of the original weighting will be granted for that assessment.
Reassessments will only be granted to students who were either unsuccessful in the first attempt or have an approved special consideration application.

A final test worth 35% will be offered to students who have achieved CA.
