Abstract:

The challenge of communicating document caching policies from document servers to client processes in the most generally applicable manner is solved by enabling the application of caching policies to classes of documents, rather than single instances of documents. Caching policies are applied to a given class of documents by specifying caching policies in metadata that describes the structure of the class of documents that conform to the metadata. In the context of XML data documents and document fragments, an XML schema can be annotated to include a representation of a caching policy, thereby specifying the caching policy for XML data documents and fragments that conform to the corresponding XML schema.

Abstract:

A compact binary encoding technique for information that is logically hierarchically structured, such as XML data, maintains all of the features of XML data in a useable form, such as the hierarchical structure underlying the data. Hence, data encoded in this format can undergo XML-based processing on-the-fly as it is being received or fetched, as if the data was being processed linearly in its textual character-based format. Processing of data encoded in this format can begin without having to wait for and decode the entire data set. The overhead due to XML tags is significantly minimized. The encoded data can be processed more efficiently because the data is pre-parsed. Values may be stored in their native type formats and, therefore, processing of the encoded data avoids costly type conversions. Further, any available structural constraint information can be effectively exploited.

International Classification:

G06F 15/16

US Classification:

709203

Abstract:

A system and method for providing asynchrony in web services, such as Java-based web services, including in some instances use of a distributed in-memory data grid. Embodiments of the system allow a client application or client to make requests upon a server application or service. A queuing feature, such as one or more Java Message Service (JMS) queues, can be used to store incoming requests at the server side, to support asynchronous behavior. In accordance with an embodiment, instead of or in addition to JMS, the system can use a distributed in-memory data grid, such as Oracle Coherence, to provide queuing functionality.

International Classification:

G06F 944

US Classification:

395701

Abstract:

A method and apparatus for implementing a data construct, referred to herein as a "cursor variable", that has many of the attributes of simple variables and that can be used to access active sets of data from a database. Cursor variables identify a current set of data in an active set generated as a result of a database query. A cursor variable can be associated with any one of a number of different queries at any given time during program execution without using a host programming language. As a result, different active sets having different columns, different tables, and/or different predicates may be associated with the same cursor variable using instructions from a single programming language.
