Abstract

A method for program execution includes providing an execution environment for a program including a structured data storage system (SDSS) capable of accessing storage locations of a structured data store using corresponding logical identifiers. The data store is structured according to a schema known to the SDSS. The exemplary method allows an addressable entity of the program to be stored at a storage location of the data store associated with a corresponding logical identifier. The addressable entity is stored in conformance with the schema as a result of at least one of compiling a source code representation of the addressable entity, interpreting an intermediate code representation of the addressable entity, linking the addressable entity to other addressable entities, and loading the addressable entity into the execution environment. The exemplary method allows a processor executing a machine code instruction of the program to access the addressable entity using an address corresponding to the logical identifier as an instruction operand during execution of the instruction.
