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_ Product Product_ Product_ Customer_ Customer_ Description UnitPrice No Phone No No Which partial dependency does this dataset have? Identify the partial dependency using the format in the example below. Example) Partial Dependencies: Customer_ Order_ Shipping Address Address Date (ProjectNum → Proj_Name) (Emp_Num → Emp_Name, Job_Class) Order_ Qty Then, which transitive dependencies does this dataset have? Identify the transitive dependencies using the format in the example below. Example) Transitive Dependencies: (ProjectNum → Proj_Name) (Emp_Num → Emp_Name, Job_Class) We learned about two types of functional dependencies, Partial Dependency and Transitive Dependency, and they are critical clues for the identification of tables.
