Over the last two decades the growth of Information Systems has grown vastly including the development of IT and the applications. Information systems are more than just a database or a computer program. It is a set of processes, tools and standard that allows us to manage information strategically, work efficiently, support business processes, communicate effectively and the most importantly is to make better decisions
The first business application of computers (in the mid- 1950s) performed repetitive, high-volume, transaction-computing tasks. The computers” crunched numbers” summarizing and organizing transactions and data in the accounting, finance, and human resources areas. Such systems are generally called transaction processing systems.
· Management Information Systems: these systems access, organize, summarize and display information for supporting routine decision making in the functional areas.
· Office Automation Systems: Typically, these type of processing systems were developed to support office and clerical workers.
· Decision Support Systems: These were developed to provide computer-based support for complex, nonroutine decision.
· End- user computing: The use or development of information systems by the principal users of the systems’ outputs, such as analysts, managers, and other professionals.
· Infinite data center: The movement toward smaller size but greater density in data centers, combined with a trend to analyze performance per kilowatt, is leading to energy management as a newer type of discipline, even for moderately energy-intensive organizations.
· Hybrid clouds: Through next year, more than 60% of enterprises will have some form of cloud adoption, and the majority will be exploring private and public cloud techniques, in what’s called a hybrid cloud. Into the next three years, private cloud focused on service-centric delivery of IT services to the organization will emerge.
· Software-defined networks virtualizing the data center: Over the next few years, there will be software-defined networks designed that have basically separated hardware from software in a way that will slowly do away with the “box-by-box” approach and “handcrafted configurations” of today, where tomorrow there will be an “automated workflow” for the next-generation data center.
In a competitive global environment, organizations need to build a flexible and robust information systems infrastructure. However, ISI should not be looked at only from the technological perspective, but it should also include human as well as organizational capabilities. There has been a rapid development in ISI over last 30 years. The IS architecture has evolved from mainframe computing to client–server computing and now component-based Internet computing.
