Overview of events for the week of 27/04/2009 to 03/05/2009. In a world of rapidly spreading outbreak of a new influenza virus of swine influenza outbreak which was recorded in North America, is spreading rapidly around the world. In Mexico, officially confirmed that the virus H1N1, or swine flu has killed more than 160 people.

In the spread of the virus in Mexico taken unprecedented measures: closed schools, canceled events, closed a number of theaters, museums and exhibitions. Cases or suspected that the virus is also available in the U.S. Canada, United Kingdom, New Zealand, Spain and France. Experts note that the swine could mutate and become even more dangerous. Currently, as noted by the who, people have no immunity to the type of virus that now spreading rapidly across North America and is threatening pandemic worldwide. On the basis of epidemiological evidence of sustained transmission from person to person, at least two countries in one region, who has decided to increase the phase of readiness for the fight against swine flu from fourth to fifth.

For the development of any system of information, the planning of the same is important. Dennis (2005) says that the planning is the basic process to understand why a system of information must be constructed and to determine as to work so that the same it is constructed. During the planning of a process it is necessary that if vest the biggest number of data and possible information on the functions that the informatizado system must contain. The system analyst must possess knowledge technician on the area where the system will be developed, and must also change information with using futures she manages and it of the company which is being developed the project. This process generates a document series for the analyst. Some of these documents are elaborated of the communication between the analyst and the too much parts that will use such system. This interaction is called of survey of requirements, that guide the analyst in the process of modeling of the information system. But what he is one requirement? For Dennis (2005) requisite it is a declaration of what a system must be, to make and which characteristics must possess.

Then, the requirements are the transcription of the data informed for the members of an institution, interested in the development of an information system, in a way that can be used by the analyst in the development of the project. The requirements can be functional or not functional. The functional requirements have relation with the actions that the system must execute, and the not functional ones define as these actions must occur. Dennis (2005) says that requisite functionaries if relate directly with a process that the system must execute, while the not functional ones mention the mannering properties to it of the system. So that an information system is efficient, it is necessary that it does not have errors in the phase of survey of requirements, and although to be common the sprouting of new requirements during all the different phases of the project is important that the analyst of systems has sensitivity in defining which requirements is really necessary so that one does not occur ‘ ‘ inchao’ ‘ in the project and unnecessary alterations in the routes of the same. The process of survey of requirements is extremely important during the development of an information system, and the correct analysis of such requirements is vital so that the developed system reaches the effectiveness.

All the phases of a development project and modeling of an information system have its utility, however, it is evident that with a correct survey of requirement ally to the knowledge of the analyst to the market area which software will be developed they become the practical modeling simplest and.

The Google Shopping already is operating in Brazil as plus one of the search tools ' ' paralelas' ' of the objective Google that, some form, to organize the information of the Internet and with them to leave still more excellent the result of the research of its main tool. The Google Shopping is different of other sites for what it makes and what does not make. The Google Shopping searches the biggest repository of traders and products of the Internet and shows quickly resulted excellent for definitive search and makes possible that the users obtain to compare prices and functionalities of these products. Many people had asked to me if the Google Shopping is equal to the Buscap or other comparators of prices of the market, and the reply it is yes and not. Yes, therefore the interface of it is very seemed the price comparators. Not, therefore the Google Shopping uses other criteria to classify the results that it shows. The products that will be shown first are the ones that the Google considers more excellent for that search and not them companies who are paying more to appear. The Google Shopping goes to help me to vender more?
