This homework is designed to give you some initial familiarity with SQL queries.
Using Visual studio, connect to the SMALLBANKDB database on the server f-sg6m-s4.comm.virginia.edu. This vLab may help. You need to be logged in the School network to do this, either from the building or using a VPN. Use the Handout linked from the class schedule to learn more about SQL.
Create queries that answer the business questions asked by your boss and listed below. Save all the queries (the SQL, NOT the results) in a single notepad file (not a word docx) and submit it. In other words, simply copy and paste all the queries in one notepad file. Name the file homework.sql. This is the only file that you need to submit. No zipping required. DO NOT add anything else to the file. No name, date, number, comments, etc.
The last two queries are significantly more challenging that the first six. Consider skipping them if too hard. Each incorrect query gets a .25 deduction. The database might contain a little more tables than the ones shown in class. Ignore them. They are used in later exercises.
