摘要:
Described herein are systems and methods for importing and retrieving schema mappings while preserving privacy and confidentiality so that existing mappings can be reused across different customers without allowing reverse engineering of the original schemas. The disclosed embodiments provide different levels of mapping anonymity and correspondingly, available structural information in the retrieved mappings, in accordance with the security and privacy requirements.
摘要:
Deployment plans, to service execution environments, of component services associated with a composite service associated with an analysis of data generated by one or more data sources, may be determined, the composite service including an ordering of execution of the associated component services for the analysis of the data. An evaluation of each of the deployment plans of the component services may be determined based on a first metric associating one or more weighted values with a consumption by the each deployment plan of one or more respective resources associated with each of the first and second network nodes and on a second metric associating one or more weighted values with a measure of connection availability of one or more network links included in a communication path between the first and second network nodes. A recommendation including one or more of the deployment plans may be determined based on the evaluation.

摘要:
A method and system are described for including data quality in data streams. An example method may include obtaining a first group of data items, each data item including one or more data attribute values. A first group of data quality items may be determined, each data quality item including one or more data quality attribute values associated with one of the data items of the first group. A first aggregated data quality value may be determined based on the first group of data quality items. A first data stream interval including the first group of data items and the first aggregated data quality value may be output.
摘要:
A remote device (100) having the ability to transmit data across a plurality of wireless channels selects the transmission channel for transmitting the data message (110). The remote device (100) prioritizes the data message (110) based on an examination of the data message (110) relative to predetermined priority settings. Based on this prioritization and in relation to a transmission prediction term, the remote device (100) assigns the data message (110) to a message queue (106) associated with the selected transmission channel. When the remote device (100) enters the transmission range of the selected channel, the data message may thereupon be wirelessly transmitted.
摘要:
Prioritized transmission of data from a mobile device, where the mobile device includes the ability to transmit data using more than one transmission medium, includes generating data packets (116) from sensor data (114). The data packet (116) is then assigned a priority level based on the sensor data (114) and various factors relating to the transmission mediums. The priority level may be assigned based on the transmission availability, bandwidth and cost of using the medium. The data packets (116), based on the assigned priority level, are then stored in a corresponding priority buffer (108) associated with a transmission device using one of the transmission mediums. When available, the transmission device may then readily transmit the data packet (116) from the priority buffer (108). Therefore, the data is transferred in a prioritized order based, in part, on the transmission medium and factors relating to the medium, as well as the sensor data (114) being transmitted.
