A computer-based information system (CBIS) is key to today’s businesses. It evolved from old ledger systems to now turn data into useful insights. Laudon’s work shows it helps make better decisions at all levels.
It has five main parts. Hardware gives the system power, and software handles tasks. Data is kept accurate, and rules help keep things consistent. People are also vital for understanding results and coming up with new ideas.
Big retailers use these systems a lot. They check stock levels, track money, and make shopping personal. This move from paper to digital shows how important they are today.
Getting it right means combining tech skills with human insight. Together, they form adaptive frameworks that tackle big problems. This includes managing supply chains and meeting customer needs.
Understanding Computer-Based Information Systems
Today, companies use digital systems to turn data into useful information. This part looks at how computer-based information systems (CBIS) have changed how we make decisions. They’ve moved from using paper to using smart data systems.
Defining the Digital Backbone
A CBIS is made up of hardware, software, and people working together. It’s different from keeping records by hand because it can process data in real-time. It helps make decisions and improve how things work.
From Filing Cabinets to Cloud Storage
The story of CBIS started in the 1960s with systems for handling transactions. Banks were among the first to switch from paper to digital records. Here are some important moments:
- 1970s: Management information systems (MIS) were introduced
- 1990s: Enterprise resource planning (ERP) software became common
- 2010s: Cloud-based analytics tools were developed
Cross-Industry Implementation
Now, CBIS are used in many fields. The NHS uses systems to keep up-to-date medical records, cutting down on mistakes. Stores use them to manage stock and predict what to order next.
These systems fit into Laudon’s framework for decision-making:
| Operational Level | Tactical Level | Strategic Level |
|---|---|---|
| Transaction processing | Resource allocation | Market expansion analysis |
| Daily sales tracking | Staff scheduling | Five-year forecasting |
Essential Hardware Components
Today’s businesses need connected hardware to run their key operations. These systems are the heart of data-driven work, needing careful setup to ensure they work well, stay safe, and can grow.
Central Processing Units and Servers
Modern CPUs are like digital workhorses, handling up to 5.7 billion tasks per second in top models. They do more than just calculate, they also decide which tasks to do first.
- They handle many tasks at once
- They adjust power use to save energy
- They have built-in security to spot threats fast
Role in Data Processing
Big banks like JPMorgan Chase use adaptive CPU clusters to handle 450 million transactions daily. These setups can shift tasks during busy times, keeping responses quick.
Enterprise Server Configurations
Top data centres now offer 99.995% uptime, thanks to Tier IV setups. Leading enterprise server setups mix:
| Component | Financial Sector | Healthcare Systems |

Software Architecture Fundamentals
Today, companies use layered software architectures to link hardware with business goals. This structure helps grow and keep things safe, which is key in finance and energy. It’s built on three main parts: system software, special apps, and middleware.
System Software Essentials
System software is at the heart of digital systems, with operating systems managing hardware. For example, JP Morgan Chase uses Linux kernel optimisations for fast trade execution. They focus on quick data processing during market times.
Security Protocol Management
Now, fighting cyber threats involves both machines and humans. The 2023 OAS framework suggests:
- Adding biometric checks for access
- Encrypting data in real-time
- Regularly updating security patches
Application Software Types
Today, enterprise software is more than just tools. It’s becoming a key asset. Companies are picking between custom-made platforms and modular systems, each with its own benefits.
Custom CRM Solutions
Salesforce’s Lightning Platform shows how CRM customisation boosts sales. Target, for example, sped up lead conversion by:
- Using AI for recommendations
- Creating special pricing for dealers
- Building mobile tools for field services
ERP System Implementations
Even though SAP S/4HANA is big in manufacturing, ERP implementation challenges are real. A Deloitte study found 43% of projects go over budget because of:
- Old system problems
- Staff not wanting to change
- Complicated data moves
Middleware Integration Strategies
National Grid’s SCADA update shows how vital middleware is. They linked old systems to Azure IoT Hub with:
- Protocol translators
- APIs for connections
- Edge computing for safety
This mix cut outage response times by 68% while keeping old systems.
Data Management Frameworks
Today’s businesses need structured ways to turn raw data into useful insights. They use frameworks to manage and protect their data. These frameworks also help meet legal standards.
Database Management Systems
Modern systems mix precise relational databases with NoSQL scalability. For example, NHS trusts use Oracle for patient records. This ensures data accuracy. At the same time, MongoDB handles imaging data with flexibility.
SQL vs NoSQL Architectures
SQL databases are strict for financial data. NoSQL is better for fast changes in e-commerce. Amazon shows how document stores update data models without stopping.
Tesco uses a mix of Hadoop and Snowflake for data storage and analysis. This combination helps with both historical analysis and daily operations.
Information Processing Models
Businesses pick processing methods based on how quickly they need decisions:
