Executive information system
An executive information system (EIS) is a type of management information system intended to facilitate and support the information and decision-making needs of senior executives by providing easy access to both internal and external information relevant to meeting the strategic goals of the organization. It is commonly considered as a specialized form of decision support system (DSS).[1]

Components
The components of an EIS can typically be classified as:
Hardware
When talking about hardware for an EIS environment, we should focus on the hardware that meet the executive’s needs. The executive must be put first and the executive’s needs must be defined before the hardware can be selected. The basic computer hardware needed for a typical EIS includes four components: 1. Input data-entry devices. These devices allow the executive to enter, verify, and update data immediately 2. The central processing unit (CPU), which is the kernel because it controls the other computer system components 3. Data storage files. The executive can use this part to save useful business information, and this part also help the executive to search historical business information easily 4. Output devices, which provide a visual or permanent record for the executive to save or read. This device refers to the visual output device such as monitor or printer
In addition, with the advent of local area networks (LAN), several EIS products for networked workstations became available. These systems require less support and less expensive computer
