Software integration is the process of connecting different software applications to work together as a unified system. This allows data and functionalities to be shared seamlessly, improving efficiency and reducing the need for manual data entry. For example, integrating a Customer Relationship Management (CRM) system with an email marketing platform can streamline communication and enhance customer engagement. There are various methods for software integration, including Application Programming Interfaces (APIs), middleware, and data integration tools. These methods help ensure that different systems can exchange information in real-time, enabling businesses to make informed decisions based on up-to-date data.
