The area requires a considerable investment, as much to be implemented as to keep its activity, and this must have a return, that strategical and/or exactly intangible. For this, the company has that to control innumerable 0 variable and data. The Administration of Computer science, as well as the administration of other organizacionais areas, must consider the principles and theories of the general management, not being convenient that it is played of a form total distinct and particular. It is important to always carry through the mappings and analyses, identifying activities, ruptures in the interconnection between these, lacks or redundancy of information, that had implied in the rationalization of procedures, junction of operational areas, monitoramento of activities, greaters easinesses and security in the attainment of information for users authorized and to the public with significant reduction of effective stated periods. Valley to always stand out the importance of the analysis and mappings, intent to the fact of that the information systems must be constructed of improved form, searching to take care of in such a way to the necessities of the users in the aspect of the trustworthiness how much in the one of the agreement of the information. 8. Conclusions Although all the technological advances, the processing of corporative information continue being complex and deserving of special attention.
One of main the critical ones that can be made in relation to the systems of information for support decision, is its construction on the basis of a linear process of cause and functional effect, that comes to obey an analytical reasoning. However, given the current technological advances, a System of Information is the main instrument for the development of strategies. It is by means of it that if it is possible to enclose all form to generate, to store, to propagate and to process the information. From there its extreme importance for a good management.
