Program integration is the process of enabling separate software programs to work together by sharing data and coordinating behavior. It aims to create a coherent system from heterogeneous applications, whether on premises, in the cloud, or in hybrid environments.

Integration can focus on data, application interfaces, or business processes. It typically begins with identifying data exchange requirements, interface contracts, and compatibility of data models. Common approaches include point-to-point connections, middleware solutions, API-based integration, and event-driven architectures.

Architectural patterns include hub-and-spoke (or broker), service-oriented architecture, and microservices with lightweight connectors. Integration platforms and middleware such as enterprise service buses and iPaaS provide orchestration, transformation, and monitoring capabilities. Adapters and connectors reduce coupling to specific applications.

Technologies and standards commonly used include APIs based on REST or GraphQL, messaging protocols such as AMQP or MQTT, data formats like JSON and XML, and data modeling standards (JSON Schema, XML Schema). Security and governance rely on protocols like OAuth2, TLS, and proper access control, auditing, and versioning.

A typical lifecycle includes requirements gathering, solution design, development, testing, deployment, and ongoing governance. Key challenges include data quality, semantic alignment, latency, versioning, security, and the risk of vendor lock-in. Successful integration projects emphasize clear ownership, reusable components, and robust error handling.

In practice, program integration enables enterprise dashboards, synchronized CRM/ERP data, process automation, and cross-system analytics. Trends include API-first strategies, event-driven and streaming data integration, low-code connectors, and AI-assisted data mapping.
