IBM mainframes commonly use the DB2 database management system. DB2 is designed for high performance and scalability, making it suitable for enterprise-level applications. Additionally, mainframes may also utilize other databases like IMS (Information Management System) and VSAM (Virtual Storage Access Method) for specific data processing needs.
