Deploying plurality of sanpshots storing parameterized data description language strings with substitutable parameter causes database object to be instantiated

Mass deployment of snapshots is fostered by allowing collections of snapshots, called refresh groups, to be defined by a template. The template allows for a parameterized snapshot definition query or other DDL text to be defined, so that user-specific or site-specific values can be substituted into parameters to create different objects. Furthermore, off-line instantiation of snapshots is provided, so that the data for an entire suite of front office applications can be stored. on a floppy disk, magnetic disk, CD ROM, or other transportable computer-readable medium.
