During the early years, information systems were centralized and concerned solely with governance and the needs of management. Most information systems and their reports were under the control of accounting departments. Technology at the time included third-generation mainframe computers such as the IBM 360 and minicomputers. Languages used include Assembler, Fortran, COBOL, and Database. Ethernet networks were developed during this time.

First Era (The mid-1960s to Mid-1970s): Mainframe and Minicomputer

While information systems were still concerned with governance and the needs of management, more departments were beginning to benefit from the technology. In many companies, steering committees and user-led initiatives determine the scope of additional information systems projects Technology included the first personal computers (PCs) and mid-range computers.

Second Era (The mid-1970s to Mid-1980s): Personal Computer

In this era, concentrated information systems started to spread, and information became deconcentrated. Technological difficulties and costs decreased, and an enterprise's need to share information grew. During this era, a new position arose in many companies to oversee the procurement and management of multiple information systems: the Chief Information Officer or CIO. Technology during this era included internetworking and the emergence of the Internet.

Third Era (The mid-1980s to Late 1990s): Client/Server

During this era, information systems are still tied to governance and management, although the systems are widely distributed to every employee who needs them across multiple platforms. This era combined all aspects of the business enterprise, offering rich information access surrounding the complete management structure.Technology now includes social media, search engines, and various computing through a variety of platforms, including laptops and smartphones.

Fourth Era (the Late 1990s to today): Enterprise

This era uses networking technology that delivers applications and data storage independent of the configuration or location of the hardware. Along with high-speed smartphones and Wi-Fi networks, this era has led to new levels of flexibility, such as cloud computing, in which managers may access information systems anywhere with a laptop, tablet, or smartphone. Rising global competitiveness has forced companies to find better and more cost-effective ways. The solution for companies continues to be to use information systems to accomplish tasks better, faster, and cheaper.

Fifth Era (Moving Forward): Cloud Computing

These handle the day-to-day business data at the operational level of the organization. It systematically processes customer transactions to generate a considerable amount of data. These will be used to learn about customers and their preferences as well as the ever-changing product trends. This is commonly applied in grocery store checkout cash registers that connect to a network. For example, the Amazon website processes thousands of transactions worldwide every hour. The collected large amount of data is then sent into data warehouseswhich will be analyzed to provide purchase suggestions to future customers.

Transaction Processing Systems (TPS)

These produce detailed and specified information to help manage a company. It is used when TPS data are sorted and organized to support a broad range of managerial decisions. It is used primarily for inventory management and planning systems. It retrieves TPS information, collects it, and generates a report for the management level to have relevant insights on a situation. Summaries and comparisons allow senior managers to optimize the decision-making process to achieve better results.

Management Information Systems (MIS)

These support a wide range of predefined day-to-day work activities of individuals and businesses. Such systems include word processors (Microsoft Word), spreadsheets (Microsoft Excel), presentation software (Microsoft PowerPoint), collaboration systems for email (Microsoft Outlook), automated calendaring, and thread discussions. These enable workers to accomplish tasks accordingly and allow close collaboration with others, regardless of location.

Office Automation Systems (OAS)

These help organizations to effectively capture, store, and retrieve organizational knowledge to help enhance learning and optimize collaboration efforts to complete tasks. Examples of documents retrieved in this include employee training materials, company policies, and procedures. These are used by the people involved within an organization to ensure that technical abilities are integrated throughout the company with visuals to help employees make sense of the data.

Knowledge Management Systems (KMS)

These analyze data and support decision-making. These are utilized by managerial-level employees to resolve problems such as sales forecasting and resource optimization, as well as to support decisions at all levels such as loan and investment analysis.These are designed to be interactive decision aid that applies models to manipulate data. For example, for historical sales data, various model types are used to create a forecast of future sales. To effectively use this, one technique is to take an average of past sales and adjust it for seasonal changes.
