Basics AutoCare is a small auto service business with two locations in a Midwest (U. S.) city. The business is based on providing routine maintenance at fixed cost to car owners. The owners have decided to computerize their operations to allow them to better track their business. Data to be gathered for each service visit includes service ID, service item, service item cost, vehicle owner, owner telephone number, vehicle make and model, vehicle year, and date of service. Assignments:1. Create an ERD for the auto service system.2. Create 3NF table designs for the system.3. For each of the entities identified, design tables and identify the possible candidate keys, the primary key, a probable foreign key, and potential secondary keys.4. Use sample data to populate the fields for three records.

Develop the program incrementally: a) start by reading and displaying each line of the input file to make sure you are reading the data set correctly. b) use the split string method to extract information from each line into a list. print the list to prove that this step is working correctly. d) convert the exam scores to type int and calculate the student’s average. display those items to prove this step is working correctly. e) create a tuple containing the six items for each student (name, exam scores, exam mean). display the tuples to prove this step is working correctly. (optionally, you may want to have the exam scores in a list so your tuple is (name, scores_list, f) append each tuple to a list. display the list to prove this step is working correctly. g) use the sort list method to re-order the tuples in the list. display the list to prove this step is working correctly. h) use a for statement to display the contents of the list as a table (with appropriate formatting). i) use a for statement to calculate the average of all scores on exam #1, then display the results. note that you could have calculated this average within the first loop, but we are explicitly requiring you to do this calculation by looping though your list of tuples. j) add the logic to calculate the average of all scores on exam #2, then display the results.
