Managing Database Object Schema Virtual Changes

A computing device for managing a database comprising a set of database objects, the computing device comprising:

• a set of processing units;
• a first storage device storing (i) a set of base physical data for the database and (ii) a plurality of sets of virtual changes for the database objects, each set of virtual changes being associated with a database object;
• and
• a second storage device storing a set of instructions, wherein an execution of the set of instructions by the set of processing units configures the computing device to perform acts, comprising:
• presenting a first query response to (i) a first application based on the set of base physical data and (ii) a first set of virtual changes for a particular database object from the set of database objects;
• and
• presenting a second query response to (i) a second application based on the set of base physical data and (ii) a second, different set of virtual changes for the particular database object.

A computer program product for managing a database comprising a set of database objects, the computing program product comprising:

• one or more non-transitory computer-readable storage device and program instructions stored on at least one of the one or more non-transitory storage devices, the program instructions executable by a processor, the program instructions comprising sets of instructions for:
• accessing a set of base physical data for the database;
• accessing a plurality of sets of virtual changes for the set of database objects, each set of virtual changes associated with a database object of the set of database objects;
• presenting a first query response to (i) a first application based on the set of base physical data and (ii) a first set of virtual changes for a particular database object of the set of database objects;
• and
• presenting a second query response to (i) a second application based on the set of base physical data and (ii) a second, different set of virtual changes, for the particular database object.
