The National Bank of Erehwon handles money and maintains bank accounts on behalf of clients. A client is a person who does business with the bank. A client may have any number of accounts, and an account may belong to multiple clients (e.g., spouses, business partners). The client record is used for identification and contact data. For each account, the bank maintains the current balance on hand. Clients are identified by a five digit number starting with 10001. Accounts are identified by a seven digit number starting with 1000001. When an account is first opened, its balance is set to zero. During the course of day-to-day business, Erehwon Bank applies transactions to accounts, including deposits, withdrawals, bill payments, and debit purchases or returns. For each transaction, the date and time, amount, and account are recorded, along with reference data applicable to that type of transaction: Deposits and withdrawals require the branch number to be recorded.…

Q1: Research Groups In response to popular demand, Dan’s established two research groups A and B composed of his n graduate students. Each of these students is a member of exactly one of the two groups at any given time. The students are numbered from 1 to n in some arbitrary order. To measure the success of his research groups, Dan assigns a citation score to each of them. Initially, both groups have citation score 0. Throughout the semester, events of the following two types happen: Student x publishes a paper in which they cite student y’s work (youcan assume all of the students have been around long enough to have prior research that can be cited). As a result, If x and y are in the same group, their group’s citation score increases by 1. If x and y are in different groups, y’s group’s citation score increases by 5. Dan changes student x’s group (from A to B or from B to A) to have them work on different projects. To assess the overall success of the research groups, Dan…
