1. Why a quality data model is needed? Explain QDM's importance in healthcare information system using examples you have seen or discussed in this Module's required readings.

2. Figure 1 in section 2.5 shows an example QDM element structure on the left. The diagram to the right is an example of QDM element called "Laboratory Test". Suppose you are member of an interprofessional team working a quality health database project for a hospital. Explain how you would design a database table to store data containing in the ODM element "Laboratory Test". For example, what is the name of this table? What are the columns to include in this table?

3. Suppose the same database contains other tables describing ODM elements such as Doctor, Patient, Medication, Pharmacy, Pharmaceutical Company, etc. Describe ONE scenario where you can use this database to address questions related to QDM element "Laboratory Test".

In order to help you understand this question, please consider the following sample scenario: Doctor A needs to find if any of his/her patients in the age group 35-55 has low HDL so that s/he can recommend them to practice regular aerobic exercise and loss of excess weight to increase the HDL level. Doctor A asks you for help since you are a health informatics analyst. Describe how you would use the database to find the answer. For example, do you need to use the database table representing QDM element "Laboratory Test"? What other tables in this database do you need to use? How will you generate the answer for Doctor A from theses database tables?
