Data management for computer systems

A computer system, comprising:

• a processor;
• a memory;
• and
• one or more computer executable instructions stored in the memory and executable by the processor, wherein the instructions are configured to implement a method for data management in the computer system when executed by the processor, the method comprising:
• a) loading into the memory a base WAD corresponding to a logical space associated with a computer application being run by the processor, wherein the base WAD contains a set of data that is uniquely associated with the logical space, wherein there are zero or more phases of activity taking place in the logical space during running of the computer application, wherein the zero or more phases are uniquely associated with the base WAD, wherein the set of data in the base-WAD remains loaded for each of the zero or more phases;
• b) for each phase of the zero or more phases, loading a different set of one or more sub-WADs into the memory, whereby there are one or more sets of sub-WADs, wherein each sub-WAD contains data that is associated with a corresponding phase of the zero or more phases;
• and
• c) managing the activity for a given phase of the zero or more phases using the common data in the base WAD and the sets of data in the sets of zero or more sub-WADS corresponding to the given phase,
• wherein each phase has a corresponding set of zero or more sub-wads,
• wherein the computer system is configured to communicate with one or more other computer systems that can access the logical space and wherein the computer system is configured to exclusively control changes of phase among the zero or more phases.

A non-transitory computer readable medium having computer-executable instructions embodied therein, the computer-executable instructions being configured to implement a method for data management in a computer system having a processor and a memory, the method comprising:

• a) with the computer system, loading into the memory a base WAD corresponding to a logical space associated with a computer application being run by the processor, wherein the base WAD contains a set of data that is uniquely associated with the logical space, wherein there are zero or more phases of activity taking place in the logical space during running of the computer application, wherein the zero or more phases are uniquely associated with the base WAD, wherein the set of data in the base-WAD remains loaded for each of the zero or more phases;
• b) with the computer system, for each phase of the zero or more phases, loading a different set of zero or more sub-WADs into the memory, whereby there are zero or more sets of sub-WADs, wherein each sub-WAD contains data that is associated with a corresponding phase of the zero or more phases;
• and
• c) with the computer system, managing the activity for a given phase of the zero or more phases using the common data in the base WAD and the sets of data in the sets of zero or more sub-WADs corresponding to the given phase,
• wherein each phase has a different corresponding set of zero or more sub-wads,
• wherein the computer system is configured to communicate with one or more other computer systems that can access the logical space and wherein the computer system is configured to exclusively control changes of phase among the zero or more phases.
