A database is both a physical and logical grouping of data.
An ESE database looks like a single file to Windows.
Its purpose is to allow applications to store and retrieve data via indexed and sequential access. A crash recovery mechanism is provided so that data consistency is maintained even in the event of a system crash.
ESE databases are organized into groups called instances.
Most applications use a single instance, but all applications can also use multiple instances.
