Nowadays, with the increasing use of information systems and the movement of organizations towards knowledge-based information systems, the effective management of data and information is one of the important concerns and fundamental operational areas of information and communication technology. In different fields of application, database management can be done with different techniques and approaches. Fuzzy logic as an effective technique is able to create an effective infrastructure and approach for the systematic management of distributed database systems. One of these fields is related to the application of fuzzy systems theory in databases, information retrieval,  expert systems and knowledge base. The most important issue that arises in fuzzy databases is how to deal with the phenomenon of uncertainty. In fuzzy logic applications, non-numeric values are often used to facilitate the expression of rules and facts of databases. In this article, the effective management framework of the fuzzy database is examined.

Nowadays one of the biggest problems of IT organizations in less developed countries is paying too much attention to infrastructure and technology of organizations. This is due to the point that many managers in organizations believe that existence of IT infrastructure and technology by itself is a sign of maturity of an organization. Although technical facilities and infrastructure such as networks, hardware, software etc., is essential for providing appropriate services and optimal performance, but these features cannot provide a competitive advantage and increase the maturity of the organization. The missing link in these organizations, which have been less considered, is how to use these features to achieve organizational goals. In different areas, there are several standards and optimal methods for defining and optimizing processes. Some of the most complex models which should be considered in different units of information technology are, models and frameworks related to IT governance. IT governance focuses on implementation and management of quality of IT services so as to meet business needs. IT governance is done by service providers through an appropriate combination of people, process and information technology. The purpose of this paper is to examine different models and frameworks of IT governance models, in order to propose a framework for assessing IT services.
