The physical environment in which you present is just as important as the story you tell. The quality of your hard work is diminished if the room is physically uncomfortable, if there are distracting noises, if you don t have an electrical outlet within reach of the projector, or if the room looks just plain shabby. Just as you have a personal responsibility for the story template, you also have a personal responsibility for the physical experience of the environment in which you present. You ll need to use your leadership and diplomacy skills to work with facilities managers or meeting planners to ensure that everything is in order. If you have access to the room where you ll present, visit it in advance of the presentation so that you can plan for your needs. When you visit the room, review the options for con guring the physical space, and rehearse the presentation in the actual environment if that s possible. If you re not able to visit the physical location in advance, contact someone familiar with the room to nd out about the room setup.

Another useful addition to a SELECT command is LIMIT. LIMIT allows you to place a limit on the amount of rows returned on a single query:

In conjunction with ORDER, you can use LIMIT to find extremes in the data. For example, finding the oldest person is easy:

Again, you follow the same procedure: Is the number to the right of the middle of the sequence If it isn t, Is it in the second quarter (to the right of the middle of the left half) and so on You keep an upper and a lower limit to where the number may be, and keep splitting that interval in two with every question The point is that this algorithm lends itself naturally to a recursive definition and implementation Let s review the definition first, to make sure we know what we re doing: If the upper and lower limits are the same, they both refer to the correct position of the number, so return it Otherwise, find the middle of the interval (the average of the upper and lower bound), and find out if the number is in the right or left half.

This sorts the rows in descending order by age and returns the first result, the highest. To get the youngest person, you could use ASC instead of DESC on the ordering.

Note Database engines sort columns automatically by their data type. Strings of text are formatted

Lighting the room properly for a PowerPoint presentation can be a challenge. On the one hand, you want people to see the screen clearly, but on the other hand, you don t want the room to be so dark that people start to doze off. Some of the latest models of data projectors have brighter displays that allow the audience to see the images on the screen clearly without turning down the room lights. When you visit the room where you ll present, try out the projector and stand at the back of the room to review things from the perspective of audience members sitting there. Adjust the lighting so that everyone in the room can see the slides and see you clearly too. Ask a facilities manager to help if the lighting controls are not readily accessible or if you need additional lighting.

The DELETE SQL command deletes rows from tables. You can delete rows based upon an SQL condition. For example:

Keep searching in the proper half The key to the recursive case is that the numbers are sorted, so when you have found the middle element, you can just compare it to the number you re looking for If your number is larger, then it must be to the right, and if it is smaller, it must be to the left The recursive part is Keep searching in the proper half, because the search will be performed in exactly the manner described in the definition (Note that the search algorithm returns the position where the number should be if it s not present in the sequence, this position will, naturally, be occupied by another number.

DELETE FROM people WHERE name="Chris" DELETE FROM people WHERE age > 100 DELETE FROM people WHERE gender = "Male" AND age < 50

At a minimum, both you and your audience should be physically comfortable in the environment. You should have a base of operations when you present, such as a podium, and you should have the physical freedom to move around the room comfortably as you speak. If you use a Tablet PC to deliver your BBP presentation, place it on the podium out of the line of sight of your audience, and make sure that the data projector cable and a power source are available at the podium. When you re comfortable with the physical environment, turn to the technology you ll use to project the PowerPoint presentation.
