摘要:
The present invention relates to a system and methodology to facilitated data object persistence. An object schema is utilized to provide metadata for types in addition to what is provided by the type system for an underlying programming language. This metadata is then utilized by the system to translate data to and from user objects during a materialization or persistence process. The object schema provides information external to programming logic and type definitions. Consequently, the object schema can be deployed independent of an application thereby allowing the persistence storage of user objects to change without force the user to recompile and deploy application code.
摘要:
A data mapping architecture for mapping between two or more data sources without modifying the metadata or structure of the data sources themselves. Data mapping also supports updates. The architecture also supports at least the case where data sources that are being mapped, are given, their schemas predefined, and cannot be changed. The architecture includes a mapping component that receives respective metadata from at least two arbitrary data models, and maps expressions between the data models.
摘要:
A device for electrically grounding bundled cables includes a first half component having an outer surface portion and an abutting surface portion, and a second half component having an outer surface portion and an abutting surface portion. The outer surface portion of the first half component and the outer surface portion of the second half component each define at least one groove longitudinally extending therealong for accommodating one of a plurality of cables held closely together in a bundled configuration. The abutting surface portion of the first half component and the abutting surface portion of the second half component are configured for engaging and cooperating with one another to form a grounding structure.
