The table shown in Figure 1 is susceptible to modification anomalies. Provide examples of insertion, deletion, and update anomalies. Describe and illustrate the process of normalizing the table to 3NF. State any assumptions you make about the data shown in this table. I want to see you take the table through appropriate structural changes to 1NF, then 2NF, then 3NF. Start by listing the functional dependencies and then resolve by modifying the table structure. Show the table structures in the following format Table_Name( primary key, attribute1, attribute2, attributeN, foreign_key) Legend Bold and underline -> primary key Italicized -> foreign key
