MIS602 Data Modelling & Database Design

Context: 

The MIS602 Data Modelling & Database Design subject is designed for you to progressively add to  your understanding of data and database management and its relevance with in business context. It  also introduces you to some of the key features of database management system and designing  database systems that will feature in later modules of this topic. In order for you to do well in this  subject, it is imperative that you undertake all of the learning activities in the modules. The learning  activities are presented as a way of scaffolding your learning so that you can attempt the building  blocks of the assessments and be in a safe environment to fail and to learn from them. Therefore,  doing your learning activities and seeking feedback from them from peers and from the learning  facilitator is the single best way of preparing for doing well in this assessment.

When you are finished this, prepare a document with all SQL commands used for each task and  summarise your experience. On the morning following submission, the learning facilitator will  allocate you another student’s document to assess. It is then your turn to assess another student’s  work. You will have three days to assess the other student’s work and to upload your response to  Blackboard. In no more than 500 words, provide a critique of that student’s work to them. You can  choose whether to identify yourself but you should provide constructive feedback, balancing good  points and points where the student can improve. You should provide feedback to the other student  on their usage of commands and summary document. You are free to use whatever framework you  like and the following should be minimum inclusions:  

• Comment on the overall usage of SQL statements and commands used  
• Provide constructive criticism on how the other student can improve their understanding of SQL  statements 
• Provide some useful readings the other student may peruse that helps them develop their  understanding of SQL statements 

Submission Instructions:  

Your spreadsheets and summary should be submitted by Thursday at midnight (Sydney time) of  week 7. Do not include any identifying information on your submission (i.e. not your student  number, name or anything else that might identify you). This is important because the peer review is  to be done anonymously. Non-submission or lateness will be treated in accordance with the late  assessment policy of the university.  

Please note that late submissions mean that another student will effectively have less time to do  their peer assessment of your work.
