Software designed for modular addition to existing computer systems enables enhanced functionality through seamless integration. For instance, an accounting program might incorporate a payroll processing capability by installing a compatible, pre-built module. This approach contrasts with developing entirely new applications, offering a potentially quicker and more cost-effective alternative.
The advantage of employing these software components stems from their ability to expand a system’s capabilities without requiring extensive redevelopment or system overhauls. Historically, this method has offered a practical solution for adapting software to evolving business needs, fostering improved efficiency, reducing costs associated with bespoke programming, and allowing for quicker responses to changing market demands. The focus on discrete functionalities promotes maintainability and upgradability.
