Question 3 a) Normalize table 1 to a set of Third Normal Form (3NF) relations. Your answer should show all the three stages of normalization (1NF, 2NF and 3NF) by using the Database Design Language format (underline all primary keys, composite keys and use an * to indicate the foreign keys). State the component(s) that is/are removed from each Normal Form. Besides that, INF must be divided into repeating and non-repeating group relations. ientID PatientName BloodID BloodType ExamDate DiseaselD DiseaseDesc |HospitallD HospitalName BO01 BO01 B001 BO08 |08/01/2020 D5001 |08/01/2020 D3222 | 11/11/2020 D5001 |11/11/2020|D7788 Hospital KL Hospital KL Hospital PJ Hospital SB |COVID-19 H223 H223 010 Alice A+ 010 Alice A+ Diabetes COVID-19 SARS 010 Alice A+ Н881 388 Thomas 0- Н666 Ipoo0 1E/11( 030lpr001 covI D 10 HEEE Hespitel Co

The following Figure 2 shows an EER schema for a database that can be used to track sales at a car dealership. Map this schema into a relational data model, including all primary keys and referential integrity constraints (foreign keys).

Q3) consider you have the Library database with the following relations, where the primary keys are underlined: Book (bookID, name, auther, No.-of-pages, section-name, category) Section(section-name, section-admin, no-of-books, library-code) Library(library-name, address, no-of-sections, manager-name, library-code, country)
Task #1 – Identification of dependencies We learned about two types of functional dependencies, Partial Dependency and Transitive Dependency, and they are critical clues for the identification of tables. In this task, we will practice how to identify the two types of dependencies, so that we can improve the results to new tables. Below is a list of attributes of a dataset. However, the attributes still have some functional dependencies, which means you can create more tables by separating some field(s). Order_ No Product_ No Product_ Description Product_ UnitPrice Customer_No Customer_ Phone Customer_ Address Order_ Date Shipping_ Address Order_ Qty Which partial dependency does this dataset have? Identify the partial dependency using the format in the example below. Example) Partial Dependencies: (ProjectNum ? Proj_Name) (Emp_Num ? Emp_Name, Job_Class) Then, which transitive dependencies does this dataset have? Identify the transitive dependencies…
