System integration involves connecting multiple applications and data sources to allow data sharing and enable integrated business processes. It includes activities like enterprise application integration, data migration, master data management, and data warehousing. System integration is important for consolidating systems during mergers, reusing applications and data, maintaining consistent functionality and data, and improving performance. It requires defining integration principles, data models, communication protocols, and service interactions.
