摘要:
The present invention relates to a system and methodology to facilitate XML data communications and processing. A diffgram data structure is provided that includes one or more states of a plurality of data records. The state information can be determined by examining one or more data sources for differences from one or more reference data sources. If differences are detected between the data sources, the diffgram can be constructed in an XML compatible format with both previous state indications and current state indications that describes the state differences between the data sources. Error information and/or other administrative information or codes can also be provided to facilitate database management and/or processing.
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.
