EXECUTIVE SUMMARY

Computers and computer-based systems are essential to any organisation today. This programmes enables you to learn how to design and implement information systems, how hardware and software work together to provide a platform for information systems, how information systems can be used in a business context, and how IT projects can be strategically managed and developed.

All medium to large organisations depend on Information technology for their continued survival. Computers are fast becoming our way of life and one cannot imagine life without computers in today's world. Since computers are used in every possible field today, it becomes an important issue to understand and build these computerized systems in an effective way

A recent article in the Daily Telegraph IT supplement suggested that many large organisations could last no longer than 24 hours without IT support! There should be little wonder that attitudes to the development of information systems have changed over the years from an ad hoc almost cavalier approach to a professionally managed, disciplined, planned, and engineering approach.

INTRODUCTION

Information systems are the means by which people and organisations, utilizing technologies, Gather, process, store, use and disseminate information.

Information technology refers to both the hardware and software that are used to store, retrieve, and manipulate information. At the lowest level you have the servers with an operating system. Installed on these servers are things like database and web serving software. The servers are connected to each other and to users via a network infrastructure. And the users accessing these servers have their own hardware, operating system, and software tools.

INFORMATION SYSTEM USE BY THE MANAGEMENT

Business managers are going from a tradition where they could ignore. delegate or avoid decision make about IT to 1 where they cannot create a marketing product, global, organization or financial plan that does not involve such decisions.

Information system also increases efficiency of existing process and making entirely new processes that are equipped with transforming the business.

The first and largest applications of computers is keeping and managing business?s, financial, input, output records. Most large companies keep the employment records of all their workers in large databases that are managed by computer programs. Similar programs and databases are used in such business functions as billing customers; tracking payments received and payments to be made, inventory, customer profile, network data and tracking supplies needed and items produced, stored, shipped, and sold. In fact, practically all the information companies need to do business involves the use of computers and information technology.

There are various kinds of information tools that can be used in management such as:

  1. TPS (transaction processing systems)
  2. MIS (management information systems)
  3. DSS (decision support systems)
  4. ESS (executive support systems)

ESS:

An Executive Support System (ESS) is designed to help senior management make strategic decisions. It gathers analyses and summarizes the key internal and external information used in the business.

A good way to think about an ESS is to imagine the senior management team in an aircraft cockpit - with the instrument panel showing them the status of all the key business activities. ESS typically involves lots of data analysis and modeling tools such as “what-if” analysis to help strategic decision-making.

CLOUD COMPUTING

Cloud computing is a rising computing technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth. Cloud computing is divided into three segments “Applications,” “platforms,” and “infrastructure.”

These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flow charts and diagrams. a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access).

Pros and Cons of Cloud Computing:

In cloud computing models, customers do not own the infrastructure they are using, they basically rent it, or pay as they use it. The loss of control is seen as a negative, but it is generally out-weighed by several positives. One of the major selling points of cloud computing is lower costs. Companies will have lower technology-based capital expenditures,. There will be more device and location independence, enabling users to access systems no matter where they are located or what kind of device they are using. One of the major topics in information technology today is data security. In a cloud infrastructure, security typically improves overall, although there are concerns about the loss of control over some sensitive data. Finally, cloud computing results in improved resource utilization, which is good for the sustainability movement (i.e. green technology or clean technology.)
