Business Information System

The information systems used in companies worldwide vary by purpose, and separate divisions of one company may employ separate systems. Examples of business information systems include:

Executive Support System
An Executive Support System (ESS) allows upper management to determine strategy and forecast outcomes critical to decision-making.

Management Information System
With a Management Information System (MIS), an organization can organize and analyze financial statements, inventory reports, and performance data.

Decision Support System 
Managers and employees require data in order to choose which direction to go, and a Decision Support System (DSS) can sift through all the data, eliminate irrelevant data, and present useful information that will justify their choices.

Knowledge Management System
A Knowledge Management System (KMS) is often used for sharing information between employees and is a useful tool when you need to immediately access company data.

Transaction Processing System
A Transaction Processing System (TPS) is just like it sounds – a system that allows the company to track transactions in every department, including billing and payroll. These systems are also used to collect customer data.

Office Automation System
One of the most commonly used Office Automation Systems (OAS) is the suite of Microsoft Office products, including Excel, Word, PowerPoint, and more. These programs improve productivity and data sharing within the organization.
