Fifth Era — Cloud computing The first era mainframe and minicomputer computing was ruled by IBM and their mainframe computers for which they supplied both the hardware and software. These computers would often take up whole rooms and require teams to run them.

The knowledge workers also need to search for knowledge outside the organization.
In addition, knowledge work systems should have user-friendly interface to help users to get the required information quickly and easily. Some examples of knowledge work systems are computer-aided design CAD systems, virtual reality systems, and financial workstations.
Computer-aided design CAD systems: These systems are used for automating the creation and revision of designs using computers and graphics software. The CAD software has the capability to provide design specifications for tooling and manufacturing process.
This saves much time and money while making a manufacturing process. These systems have more capabilities than CAD systems for visualization, rendering and simulation. They make use of interactive graphics software to build computer-generated simulations which almost look like real.
They can be used in educational, scientific and business work. They are used to combine a wide range of data from internal as well as external sources. This data includes contact management data, market data and research reports. Financial workstations help in analyzing trading situations and large amount of financial data within no time.
It is also used for portfolio management. Management Information Systems Management information systems are especially developed to support planning, controlling, and decision-making functions of middle managers.

Types of management information systems include management reporting, process control, sales and marketing, inventory control and accounting and finance.
Management Information Systems A management information system is an information system that uses the data collected by the transaction processing system and uses this data to create reports in a way that managers can use it to make routine business decisions in response to problems.
