Today, more than at any previous time, the success of an organization depends on its ability to acquire accurate and timely data about its operations, to manage this data effectively, and to use it to analyze and guide its activities. Phrases such as the information superhighway have become ubiquitous, and information processing is a rapidly growing multibillion-dollar industry. In recent years, corporations have made significant investments in information and knowledge management initiatives mainly through the development of information systems. The pursuit of higher competitiveness makes companies continuously try to apply various types of business concepts and methodologies, or information technology tools, techniques, and methods. One of the business concepts widely implemented in companies is data Management. Its scope or form is determined by the objectives of the organization and the personal objectives and needs of people inside it.

The book opens with a new approach for database fragmentation and allocation to improve the distributed database management system performance. The amount of information available to us is literally exploding, and the value of data as an organizational asset is widely recognized. Consequently, the book proposed a new technique that splits the database relations into disjoint fragments. In addition, it introduces a high-speed clustering technique that groups the distributed network sites into a set of clusters according to their communication cost. Also, it proposes a new intelligent technique for data allocation and redistribution based on transaction processing cost functions. Moreover, it implements a user-friendly simulation tool that performs fragmentation, clustering, allocation and replication of a database, in addition to assisting database administrators in measuring DDBMS performance. In the scope of corporations, information and knowledge management are essential practices that are carried out through information systems. In this book, we discuss the foundations of an ontological-based architecture for organizing information and knowledge within corporations.

The book investigates mutual interrelationship of two distinct areas, data migration processes and knowledge management programs. Basic facts together with various definitions and characteristics of both research topics are presented. The book reveals that these are closely connected in terms of how data, information, and knowledge should be created, enhanced and managed. Therefore, similarities and mutual features of both disciplines are outlined.

It also explores the role of information systems in human resource management for Sustainable Performance. The book also reveals that the lack of IT support in businesses of SMEs leads to the high cost of production, waste, delay and other challenges to organizational renewal and adaptation. One of the biggest challenges facing the organizations nowadays is the turbulent environment in which they operate. Due to this, a new view of strategic management has arisen emphasizing the significance of managing dynamic capabilities. Hence, the use of IT applications will reduce lead time, reduce operating cost and enhance product differentiation. This book will appeal to students and practitioners working in the associated field and, moreover, may provide new concepts and starting topics for future researches.
