E-based systems and computer networks are becoming standard practice across all sectors, including health, engineering, business, education, security, and citizen interaction with local and national government. They facilitate rapid and easy dissemination of information and data to assist service providers and end-users, offering existing and newly engineered services, products, and communication channels. Recent years have witnessed rising interest in these computerized systems and procedures, which exploit different forms of electronic media to offer effective and sophisticated solutions to a wide range of real-world applications.

With contributions from researchers and practitioners from around the world, this two-volume book discusses and reports on new and important developments in the field of e-systems, covering a wide range of current issues in the design, engineering, and adoption of e-systems. E-Systems for the 21st Century: Concept, Developments and Applications focuses on the use of e-systems in many areas of sectors of contemporary life, including commerce and business, learning and education, health care, government and law, voting, and service businesses.

The two-volume book offers comprehensive research and case studies addressing e-system use in health, business, education, security, and citizen interaction with local and national government. Several studies address the use of social networks in providing services as well as issues in maintenance and security of e-systems as well.

This collection will be valuable to researchers at universities and other institutions working in these fields, practitioners in the research and development departments in industry, and students conducting research in the areas of e-systems. The book can be used as an advanced reference for a course taught at the undergraduate and graduate-level in business and engineering schools as well.
