MIS602 Data Modelling & Database Design – When you are finished this, prepare a document with all SQL commands used for each task and summarise your experience
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
