System integration is the process of connecting different computing systems and software applications to work together as a unified whole. This can involve linking various hardware components, software programs, and databases to streamline operations and improve efficiency. By integrating systems, organizations can ensure that data flows seamlessly between different platforms, reducing redundancy and errors. The goal of system integration is to create a cohesive environment where all parts function together effectively. This can enhance productivity, improve communication, and enable better decision-making. Common methods of integration include using application programming interfaces (APIs) and middleware to facilitate interactions between disparate systems.
