The term reliability refers to a system's support for maintaining stability and integrity. High availability can be thought of as the ability of a system to continue serving client connections in the event of a hardware, software, or system failure. A highly available system is almost always operational and accessible to clients.
Reliability and availability are two important characteristics that define the level of quality of service offered by a database system. This chapter introduces SQL Server 2005 database engine features that make database solutions reliable and highly available.
