Chapter 1: DBMS (5 points) A long-time volunteer public skating coordinator for an ice arena in Madison wants to store information about many public skating events at this ice arena over the year so that he could provide some concrete reports to the director board every quarter. Not surprisingly, the volume of data compels him to think about using a database system. However, he wants to pick the features of a database management system (DBMS) to fit his needs only, i.e., he wants to buy/use a DBMS ! with the fewest possible features. He plans to run it as a stand-alone application on his laptop. Of course, he does not plan to share his data with anyone. Indicate which of the following DBMS features he should choose/pay for, in each case also indicate why he should (or should not) pay for that feature in the DBMS system he plans to buy. 1. Concurrency control. 2. Crash recovery 3. A reporting tool (tools used for data visualization or geneting reports from stored data). 4. A query language
