Answer to Question 1

Determining the system's requirements is the most important phase in the systems
development process. If the requirements are wrong, the system will be wrong. If the
requirements are determined completely and correctly, then design and implementation will be
easier and more likely to result in success. Examples of requirements are the contents and the
format of Web pages and the functions of buttons on those pages, or the structure and content of
a report, or the fields and menu choices in a data entry form. Security is another important
category of requirements. The easiest and cheapest time to alter the information system is in the
requirements phase. Changing a requirement at this stage is simply a matter of changing a
description. Changing a requirement in the implementation phase may require weeks of
reworking applications components and the database.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
