DATA MANAGEMENT FOR COMPUTER SYSTEMS

摘要

A computer system may load into its memory a base WAD corresponding to a logical space associated with a computer application run by a processor. The base WAD contains data uniquely associated with the logical space. Zero or more phases of activity take place in the logical space during running of the application. Phases are uniquely associated with the base WAD. The data in the base-WAD remains loaded for each of the phases. For each phase, the system loads a different set of zero or more sub-WADs into memory. Each phase has a different corresponding set of zero or more sub-wads. Each sub-WAD contains data that is associated with a corresponding phase. The system manages the activity for a given phase using the data in the base WAD and the data in the sets sub-WADs corresponding to the given phase.
