Information system – an integrated set of components for collecting, storing, and processing data and for delivering information, knowledge, and digital products. The main components of information systems are computer hardware and software, telecommunications, databases and data warehouses, human resources, and procedures.

Classification of the architecture

According to the degree distribution differs:

• desktop (desktop), or the local IP, in which all components (database, database, client applications) are located on a single computer;

• distributed (distributed) IP, in which the components are distributed across multiple computers.

Distributed IP, in turn, is divided into:

• file server IP (IP architecture “file server”);

• client-server IP (IP architecture “client-server”).

In a file-server IP database is on a file server, and database and client application are workstations. In client-server IP database and database witch (витч) reside on the server and the workstations are client applications. In turn, the client-server IP is divided into two-tier and multi-tier.

In a two-tier IP are only two types of “links”: the database server on which the database and the database (back-end), are workstations, which are client applications (front-end). Client applications access the database directly.

In multi-tier IP are added intermediate “nodes”: the application servers (application servers). Custom client applications do not access the database directly, they interact with the intermediate links. A typical example of the ladder – advanced web applications using the database. In such applications, in addition to database managers and client managers, running a web browser, there is at least one intermediate – Web server with the appropriate server software.

Classification of the degree of automation

According to the degree of automation of IP can be divided into:

• automated information systems, in which automation can be incomplete (i.e., require constant intervention of staff);

• automated information systems, in which the automation is complete, this, interaction is not required or required only occasionally.

“Manual IP” (“without a computer”) cannot exist because the existing definitions require the mandatory presence in the IP hardware and software. As a consequence, the concept of “automated information system”, “computer information system” and simply “information system” are synonymous.

Classification of the nature of the data

By the nature of the IP data are divided into:

• information and referral, and information retrieval of IP, in which there are no complex data processing algorithms, and the purpose of the system is to search for and delivery of information in a convenient form;

• IP data in which the data are processed by complex algorithms. These systems primarily include automated control systems and decision support systems.

Classification by field of application

Since the IP created to meet the information needs within a particular domain, then each domain (scope) corresponds to the type of IP. To list all of these types does not make sense, since the number of domains is large, but you can specify as an example the following types of IP:

• Economic Information System – an information system designed to perform control functions in the enterprise.

• Medical Information System – Information system designed for use in a medical or health care setting.

• Geographic Information System – an information system that provides collection, storage, processing, access, display and dissemination of spatially coordinated data (spatial data).

Classification by coverage problems (scale)

• Personal IP is designed to solve a variety of tasks of one person.

• IP Group is focused on the collective use of the information, members of a workgroup or department.

• Corporate IP, ideally, cover all the information processes of a company reaching its full consistency, transparency and breakeven. Such systems are sometimes referred to as integrated enterprise automation systems.
