摘要:
A system for evolutionary analytics supports three dimensions (analytical workflows, the users, and the data) by rewriting workflows to be more efficient by using answers materialized as part of previous workflow execution runs in the system.
摘要:
One embodiment of the invention is directed to a method including constructing a path-distance oracle that provides both an intermediate vertex of a shortest path between two vertices in a spatial network and an approximate distance between the two vertices. The constructing comprises decomposing the spatial network into a set of path-coherent pairs (PCPs) that satisfy at least one predefined property.

摘要:
A system and method are provided for data sharing. A uniform communication framework is provided as part of a sharing service on the cloud platform to facilitate data sharing among a plurality of applications. The uniform communication framework includes an application programming interface which provides a communication gateway to permit a first application to access data of a second application stored in the data store.
摘要:
A system and method for data sharing are provided. Context parameters associated with a user are gathered from a plurality of applications. A mobile context of the user is determined based on the gathered context parameters. Content is presented to the user in accordance with the mobile context of the user.

摘要:
A method to facilitate data sharing for cloud applications includes determining one or more cost levers for a cloud service provider to share data among applications; determining a costing function that considers a resource cost of creating and maintaining the sharing, potential penalties to be paid if a service level agreement (SLA) is breached by the cloud service provider, and overprovisioning of services from the provider; and interactively answering what-if questions on pricing of services to allow a consumer to explore the cost of data sharing from the provider.
摘要:
A platform as a service (PaaS) is provided as part of a data sharing scheme. The PaaS is configured to setup a materialized shared space in a cloud. The materialized shared space includes a set of resources invested by the PaaS to permit data sharing between a tenant application and at least one consumer application. A sharing middleware configured to provide the at least one consumer application with access to the data in the materialized shared space.
摘要:
A system and method are provided for data sharing. A sharing negotiation tool permits at least one consumer application to negotiate a service level agreement on a dataset which is being shared by a tenant application on a cloud. A capacity planner is configured to determine an appropriate allocation of cloud resources to ensure that the service level agreement of the at least one consumer application is satisfied.
