Lab Sessions


Given that this is a distance-learning course now, we will have virtual lab sessions as described below.

The purpose of the lab sessions is to enable you to work on assignments 1, 2, and 4. In particular, the first two lab sessions focus on assignment 1, the third lab session is primarily for assignment 2, and the rest of the lab sessions is for assignment 4 (the BrianAir project).

To attend the lab sessions (and to do the assignments), you need to register in Webreg with your lab partner.

The computer labs are done via a MySQL database server that you have access to as a participant of the course. Before you can begin with the labs, follow the instructions to set up the environment.

Virtual Lab Sessions

The virtual lab sessions are run based on the following two tools:

  • Zoom meeting rooms will serve as our virtual lab rooms. There will be one Zoom meeting room per lab group (i.e., Group A, Group B, and Group C) and your lab assistant will provide you with the details to access that room. Within this virtual lab room every pair of lab partners will be assigned a separate breakout room that serves as a virtual space for the lab partners to work together. That is, within your breakout room, you and your lab partner can talk and share your screens with one another in order to work on your lab assignments collaboratively. To this end, one of you has to take the lead in terms of doing the actual typing of your SQL code (or drawing of diagrams); this partner shares her/his screen and, then, both of you can discuss what needs to be typed. You have to agree beforehand who takes the lead, and you should take turns for the different lab sessions.
    Important: to enable the lab assistant to assign you (and your lab partner) to the right breakout room, you need to change your name within the Zoom meeting. This should be done as follows. Directly after entering the Zoom meeting, click on the "Participant list" button in the Zoom application. Next, in the "Participants" window that opens, hover the mouse over your entry in the list (typically, you are shown at the top of this list) and several blue buttons should appear, including a button called "Rename" (it may be possible that you first have to click the "More" button that appears). After clicking the "Rename" button, enter a screen name using the following pattern: <Webreg group number> <First name> <Last name> 
    If you have questions or problems during the lab session, you can ask your lab assistant for help. The way you do this is by getting into a queue using the tool described in the following; then, when the lab assistants has helped the students who have been in the queue before you, he/she is going to come to your breakout room.
  • Camedin is a simple online queuing application which we use for you to queue to get help from your lab assistant during the virtual lab sessions. Note that, as a student, you do not need to log into Camedin to get into the lab session queue. Instead, your lab assistant will provide you with a link to a Camedin "Live" page for your lab group. During the virtual lab sessions, this page is active and you can see how many people are in the queue.
    If you want to get into the queue, click on the button called "Page". Now, you have to enter i) your name, ii) your location (which, in our virtual setting, is the number of your breakout room), and iii) a password (which you have received from your lab assistant). After clicking "OK", you should see the place that you have in the queue. When it says "NOW", it is your turn and the lab assistant will join your breakout room.
