    摘要： The present invention extends to methods, systems, and computer program products for abstracting an operating environment from an operating system running in the operating environment. Within an operating environment, an operating environment abstraction layer abstracts and exposes operating environment resources to an operating system. Accordingly, appropriately configured operating environment abstraction layers provide the operating system with a uniform interface to available resources across a variety of different operating environments. Each operating environment abstraction layer and the operating system include adjustable algorithms that can be adjusted to appropriately provide services to requesting applications based on exposed resources of the operating environment. Abstraction layers can be configured to analyze and become fully aware of their operating environment, including identifying the presence of other abstraction layers. An operating system and corresponding abstraction layer can be run in flexible combinations of privileged and unprivileged processor modes.

    摘要： A system of the present invention includes a relational database management system (RDBMS). Methods are described for maintaining integrity between "design documents," which may be creating under different operating systems, and one or more information tables of the system. The system provides each field of a table with a unique ID ("field ID") for tracking the field regardless of restructuring changes which may be made to the table by various clients. Corresponding field IDs are stored with the fields of design documents, thereby permitting the system to maintain a link between a design document and its table. Upon a restructure of a table, the dependent design documents may be appropriately updated by their respective clients. Methods are also described for improved storage of free-form or "memo" data. In a preferred embodiment, memo data are stored in a separate file comprised of variable-length storage blocks. Methods are described for allocating storage space in the blocks and sub-allocating storage space within a block. For increased efficiency, the system maintains a sorted "free list" of free storage blocks.
