Prоblem Stаtement: Imаgine а database table called Student_Recоrds that cоntains 1,000,000 rows of data, but currently has NO indexes created on it. The Search Scenario: If you run a query to find a specific student ID (SELECT * FROM Student_Records WHERE ID = 900500), what method must the database use to find this record, and why is it slow? (3 Marks) The Solution: If you create a Primary Index on the ID column, how does the search method change? (You may use the analogy of finding a topic in a textbook to explain). (4 Marks) The Trade-off: If indexes make searching so much faster, why don't we just create an index on every single column (Name, Age, Address, Phone, etc.)? Give one disadvantage of having too many indexes. (3 Marks)
