Software integration is the process of connecting one software application with another, typically through their application programming interfaces (APIs). Once connected, the applications can share data and provide updates to one another in, or near, real-time.System integration is defined in engineering as the process of bringing together the component sub-systems into one system and ensuring that the subsystems function together as a system, and in information. Software integration involves combining different software systems and applications to function together as a unified, interconnected ecosystem. The goal is to enable these systems to communicate, share data, and work in harmony to streamline operations and improve efficiency. Here are the key aspects involved in software integration.
