The current paper entitled ‘Information Systems and Its Types: Based on Territory, Establishments and Domain Specific deals with the following aim and objectives—

To learn about the Systems with its application/ influence areas in a brief manner.

Information System consists of the information and various kind of components which helps in information processing and management. It is the process, systems on information related activities viz. collection, selection, processing, management, delivery. Further various techniques and technologies are also important such as Database Technology, Web Technology, Network Technology, Software Technology, Multimedia Technology and others and these are important in process of developing information systems including repositories [7], [15], [16] .

There are different ways in the classification of the Information Systems, viz (refer Fig. 1 also)—

Based on Tools and Procedure;

Based on tools and technologies Information Systems can be classified into two Manual Information Systems and Technology Oriented Information Systems.

Manual or Traditional Information Systems are those which are managed on the basis of general and non-computing based tools and accessories such as manual sheets, file, Indexing, catalogues, document register, ledger, and so on. However, manual systems are time consuming and, in the future, it may create lots of problems [21].

Technology oriented Information Systems can be managed and run with intelligent tools and systems. It is also called as computer information using computer technology with the core components of the computer and IT tools viz.—

Hardware-such as monitor, CPU, printer and keyboard and all other components which are helpful in data and information.

Traditionally Information Systems are considered as a process of computation of the information with the help of core technologies and proper systems viz.—

Transaction Processing Systems.

Here in this scenario, the Executive Information Systems consider at the highest and Transaction Processing System at the lower level in the structure.

Information Systems and Networks can also be classified based in established and management or governance also and these include—

Information Systems may be also established or formed on a specific subject or discipline. The main aim and objective of this kind of Information Systems include the collection, selection, organization, and dissemination of information. This type of Information Systems can be established on a specific micro subject or it may be a subject or on a domain or field. Organizing and involvement of this kind of Information Systems can have a territory as a national or regional.

This type of Information System is capable of the development of information repositories and other activities. Here modern information handling tools and techniques are used. Further this kind of Information Systems helpful in supports for implementing national policy on specific subjects. Here technological infrastructure plays a leading role in developing in subjects or disciplines [22].

Information System when dedicated in collect, select, organize and deliver information for some specific purpose aim or objective, thereafter such Information System can be called as Mission or Subject Specific Information System. These are also called as Object Oriented Information Systems and Networks (OOISN) and today many countries are giving thrust and importance in the establishment of the mission oriented. The mission may be on a special issue or subject or discipline centric viz. COVID, Malaria, health or transportation or AIDS, and so on [5], [10].

Information Systems on health systems.

These types of Information Systems can be National or International or State/Local level or maybe Government or Private in nature. Normally these Information Systems are computational in Nature but it can manual as well. Information Systems can be therefore established on Malaria, or health or transportation or HIV, AIDS. Information Systems may be on a specific community topic viz. Information Systems may be on railway systems, Information Systems may be on weather control [9], [12].

Information Systems can also be established based on the periphery, reach, or territorial jurisdiction. This is simply such kind of Information Systems which are based on geographical boundaries. Based on size it is normally classified and depending upon country and context it is also called as Information Systems and Network or simply Information Network. Based on reach therefore it can be-

International Level;

Information Systems which are connected or established within a group of countries, or having concentration more than one country is called International Information Systems. The periphery of information dealing activity is larger than National Information Systems. These kinds of Information Systems even may not be established or connected with many countries but may have international users. There are many similar Information Systems established worldwide viz.—

UNISIST (i.e. World Information Systems for Science and Technology).

This type of International Information Systems can also be established on a particular mission or object based viz. Air Information Systems in an International Airport (Refer Fig. 2).

The National Information Systems basically established, governed within a country. This kind of Information Systems is normally spread all over the country and mainly connected with other State or Local Information Systems or sometimes small Information Centers [4], [14],[17]. Even there are many information facilitating like—

Documentation works;

National Information Systems are connected by cables or wireless devices with small information centers in any state/province. In India, many Information Systems have been viz—

NISSAT (i.e. National Information Systems for Science and Technology).

Information Systems if established in a specific state or province then the establishment is called State Information Systems and sometimes also called as State Information Networks. In some of the countries, it is also called as Province Information Systems or Networks. In certain context, it is called Regional Information Systems and Networks. Such Information Systems basically deals with less information overload than other Information Systems i.e. International and National Information Systems or Networks. This type of Information Systems is also established in the district and combines then into a state one [4],[19]. Further in some mission oriented Information Systems building Block Level and District level Information Systems also play an important role. All of these establishments are connected via a wired or wireless way. Some of the popular Information Systems in this category are as follows—

Regional National Information Centre, Kolkata.

Local Information Systems are basically established and operated from the District or different geographical locations of the state or province. These are also called as Information Systems and Networks (ISN).

This kind of Information System is dedicated to the collection of traditional information Retrieval and storage system and sometimes plays as an Information centre. This type of Information Systems depending upon nature may be different types, viz.

Local Culture Specific.

These are the focused Information Systems dedicated to the International, National, Continental or Local level territory and helps in information development and richness [8], [11].

In the Computational context, Information Systems are normally considered as important with the collection, preservation and delivery of information of a different kind. Further many Information Systems dedicated to the organizational support only viz. Executive Information Systems, Decision Support Systems, etc. Technologies such as Cloud Computing, Big Data, Data Analytics, Human Computer Interaction, Usability Engineering, AI and Robotics, etc are important in developing Information Systems. Proper efforts in Information Systems can help to make a developed information base and especially healthy organizations and institutions. Territory based Information Systems are important and valuable in developing healthy information systems and complete information infrastructure in many contexts.
