Assume we hаve а relаtiоn cоntaining custоmer information of a bank with the schema below: Customer(customerID, branchID, zip, income, balance) We know the following facts about the data stored in this relation: (1) There are around 100,000 records stored in the relation; (2) there are 20 different branches, and each branch roughly has the same amount of customers; (3) Around 50 customers reside in each distinct zip code. A workload with three types of queries is executed against this relation. All three types show up at a similar rate in the workload. The three query types are: • Query 1: Retrieve customer information with a given CustomerID; • Query 2: Get the average income of customers in a continuous zip code range of size 10. (e.g., 16803 - 16813) • Query 3: Calculate the balance sum of all customers in a branch with a given branchID. (a) [6 points] You now have a chance to build two indexes on this table and justify your choice. (b) [4 points] What type of index are they (Hash, B+Tree)? [Hints: remember the rules of creating an index: Make some attribute K a search key if the WHERE clause contains: An exact match on K A range predicate on K A join on K Try to create index that covers multiple workloads Try to select a index based on the frequency of the workload Try to select a index on a workload that is more selective ]
