Information systems support processes and activities in an organization. They help create, collect, process, store, and disseminate information and are a major component of information technology.

There are different types of information systems, depending on their purpose and the kind of information they deal with. Let’s look at the various information systems and their applications in detail!

1. Transaction Processing Systems

All organizations need to process sales, purchases, payments, and orders; a Transaction Processing System (TPS) handles these transactions. TPSs usually use a database to store information about customers, products, and prices. They also use software to help with tasks such as order entry, inventory management, and billing.

Transaction Processing Systems are used to process and store transactions, such as sales, invoices, and payments. These systems capture and process data about transactions and record information such as sales, customer orders, payroll, and billing. TPS systems use business rules to validate and process transactions. They also generate reports that give information about the organization’s financial performance. Using a TPS can help improve an organization’s efficiency by automating transactions and reducing processing time.

2. Operational Support Systems

Operational Support Systems (OSS) automate and improve the efficiency of tasks essential to an organization’s day-to-day running. OSSs are typically used by telecommunications companies and help with tasks such as network management, billing, and customer service. In addition, they provide the information needed for decision-making, such as information about the current state of the network, the location of assets, and performance data.

They also provide information to help managers make better decisions about their business operations. For example, a network management system can provide network performance, usage, and security information. This information can help managers identify problems and make changes to improve the network’s performance.

3. Decision Support Systems

Decision support systems (DSS) are information systems that help managers make decisions. DSS uses analytical tools such as models and simulations to generate information about different scenarios. For example, a DSS could evaluate the financial impact of opening a new store in a particular location.

A DSS is interactive and allows managers to modify the displayed information. This means that they can get information about the consequences of their decisions and see how different scenarios would affect their business. DSSs also allow managers to share information with other team members so that everyone has the same information when making decisions. The organization can use this information to decide what products to sell, where to locate new stores, and how to market products.

4. Management Information Systems

Management information systems (MIS) are valuable tools for mid-level managers to optimize their planning and decision-making. MIS also helps managers to track the performance of their organization. They can use this information to identify areas where they need to make changes for improvement.

MIS usually contains information about the performance of the business, including data on sales, profits, and costs. It also includes information on the resources used, such as the number of employees and the amount of inventory. These systems collect data from TPS and other sources, then process and store the information in a database. Finally, MIS systems use the database to generate reports that give managers information about their business performance.

5. Office Automation Systems

Office automation systems (OAS) are the various tools used to perform clerical and managerial tasks in an organization. These tasks include word processing, email, and data entry. OAS is the software that allows employees to create documents, send emails, and manage their calendars. They can improve the efficiency of these tasks by automating them. For example, a word processor can automatically format a document according to an organization’s style guide.

One of the benefits of using an OAS is that it can help employees be productive. They can create documents quickly and easily, stay organized and track their progress. Thus, they have more time to focus on essential tasks. Office Automation Systems can also help managers communicate with other team members. For example, they can use OAS to send emails and share documents for easy collaboration.

6. Knowledge Management System

A Knowledge Management System (KMS) manages and shares knowledge within an organization. It allows employees to store, access, and share information about the products, services, and processes that the organization uses.

KMS can help to improve communication within an organization by providing a central repository for information. This information can be accessed by anyone in the organization, making it easier for employees to find the information they need. Additionally, KMSs can help improve an organization’s efficiency by reducing the amount of time that employees spend searching for information.

7. Executive Support System

An Executive Support System (ESS) is a type of information system that senior managers use. It provides them with information about the performance of their business and the resources that are being used. ESSs typically include information about the business’s financial performance, including data on sales, profits, and costs. Additionally, ESSs can also provide information about an organization’s customer base, including data on customer satisfaction and customer loyalty.

8. Expert Systems

An expert system is a type of information system that uses artificial intelligence to provide advice or recommendations to decision-makers. It is designed to help humans make better decisions by providing them with the information they might not have otherwise considered.

Expert systems can be used in various fields, including medicine, finance, and law. They can help decision-makers make better decisions by providing them with information based on the expertise of others. Additionally, expert systems can also help improve an organization’s efficiency by reducing the amount of time that employees spend searching for information.

9. Process Control Systems

A process control system (PCS) is a type of information system used to manage and monitor a process. It collects data about the performance of the process and uses it to make decisions about how to improve the process.

PCSs are typically used in manufacturing or other industrial settings. They can help improve the efficiency of a process by ensuring that it is running smoothly and efficiently. Additionally, PCSs can also help to improve the quality of a product by ensuring that it meets all necessary specifications.

10. Enterprise Collaboration System

An enterprise collaboration system (ECS) facilitates communication and collaboration between employees. It allows employees to share information, ideas, and files. ECSs can help improve communication within an organization by providing a central repository for information, and anyone in the organization can access this information.


Information systems are used to manage and share information within an organization. There are various types of information systems, including knowledge management systems, executive support systems, expert systems, process control systems, and enterprise collaboration systems. Each type of information system has its unique applications and can help improve an organization’s efficiency or performance.
