What is the primary purpose of integration in application development?

The primary purpose of integration in application development centers around enabling data exchange with other systems. Integration allows different software applications to communicate and share data seamlessly, which is essential for creating cohesive and functional ecosystems. By facilitating this exchange of information, developers can ensure that applications work in harmony with existing systems, databases, and services, allowing for improved workflows and enhanced functionality.

Moreover, integration can involve connecting to various data sources, APIs, or third-party services, which can help expand the capabilities of an application and provide users with comprehensive data and insights. This ability to share and utilize data from multiple sources is crucial in today's interconnected digital landscape, making integration a vital aspect of application development.

While enhancing user interface design, streamlining authentication processes, and optimizing application performance are important considerations in the development lifecycle, they often rely on the successful integration of data and services to be fully realized. Without effective data exchange, the application may struggle to provide a unified user experience or access essential information, highlighting why integration stands out as the primary purpose.
