Computer-Based Information Systems: Significance & Types
1. Introduction
In the digital era, information is considered as valuable as capital or labor. Organizations rely on Computer-Based Information Systems (CBIS) to collect, process, store, and distribute data to support decision-making and operational efficiency. A CBIS integrates hardware, software, databases, telecommunications, people, and procedures to transform raw data into meaningful information.
2. Significance of Computer-Based Information Systems
a) Efficient Data Management
CBIS enables organizations to store, organize, and retrieve vast amounts of data quickly and accurately, replacing manual record-keeping.
b) Improved Decision-Making
By providing timely, accurate, and relevant information, CBIS helps managers make informed strategic and operational decisions.
c) Automation of Tasks
Routine business processes such as payroll, billing, and inventory tracking are automated, reducing human error and saving time.
d) Competitive Advantage
Organizations can analyze market trends, customer preferences, and competitor activities, enabling them to stay ahead in business.
e) Enhanced Communication
Through networking and integrated platforms, CBIS allows seamless communication across departments, branches, and even countries.
f) Cost Reduction
Automation and streamlined processes lower operational costs while improving productivity.
3. Types of Computer-Based Information Systems
CBIS can be categorized based on their purpose and level of use within organizations:
1. Transaction Processing Systems (TPS)
Purpose: Record day-to-day routine transactions.
Examples: Payroll system, order processing, ATM transactions.
Users: Operational staff.
2. Management Information Systems (MIS)
Purpose: Summarize and report on basic operations of the organization using data from TPS.
Examples: Sales reports, production schedules, financial statements.
Users: Middle managers for tactical decisions.
3. Decision Support Systems (DSS)
Purpose: Assist managers in decision-making by analyzing data and presenting models.
Examples: Forecasting systems, budgeting tools, medical diagnosis support.
Users: Managers and analysts.
4. Executive Information Systems (EIS) / Executive Support Systems (ESS)
Purpose: Provide top-level executives with quick access to key performance indicators and strategic information.
Examples: Dashboards with financial health, market trends, competitor analysis.
Users: Senior executives.
5. Knowledge Management Systems (KMS)
Purpose: Capture, store, and share organizational knowledge and expertise.
Examples: Document repositories, research databases, intranet-based knowledge portals.
Users: All levels—employees, managers, researchers.
6. Expert Systems (ES)
Purpose: Mimic human experts by applying reasoning and knowledge to solve problems.
Examples: Medical expert systems, troubleshooting systems, legal advisory tools.
Users: Professionals requiring specialized support.
7. Enterprise Systems (ERP)
Purpose: Integrate all functional areas (finance, HR, supply chain, manufacturing, marketing) into a unified system.
Examples: SAP, Oracle ERP, Microsoft Dynamics.
Users: Organization-wide (managers, employees).
4. Conclusion
Computer-Based Information Systems (CBIS) are the backbone of modern organizations. They not only automate tasks but also provide strategic insights, fostering efficiency, innovation, and competitiveness. From transaction systems at the operational level to executive systems at the strategic level, CBIS supports decision-making at every organizational tier. In an age driven by data and technology, effective use of CBIS is crucial for growth and survival in a dynamic environment.
