Question 2. Download the database conference.mdb. This database describes the sessions and speakers at a conference. Again, for each of the queries specified below, write the corresponding SQL code in a Word file or PDF (you can test your SQL code in Access to make sure it returns the correct data, but you are not required to submit the Access file with the queries). 1. Create a "master schedule" table for the conference: For each talk at the conference, this table should list the date, session start time, session title, room, speaker first name, and speaker last name. It should be sorted by date, then by session start time, then by session title, then by speaker last name. 2. Create a table containing the ID, name, date, and start time of each session, along with the number of speakers scheduled for the session. Sort the results by date (earliest to latest), and for sessions on the same date, sort from the largest number of speakers to the smallest. 3. Show the average capacity of rooms that either have a large screen or have the ability to serve refreshments (or both). (The result of this query should be single cell.) 4. For each speaker, show their names and the number of talks they will give at the conference
