A data processing system () connected to a plurality of first applications () and a plurality of second applications () includes a setting information generation function section (), wherein the setting information generation function section includes a first interface generator () configured to generate a first interface for the first applications, a second interface generator () configured to generate a second interface for the second applications, and a storage () to store common data structure generation source information which is common information based on which the first and second interfaces are generated, and when the common data structure generation source information is updated, the first interface generator and the second interface generator automatically generate the first interface and the second interface, respectively, based on the updated common data structure generation source information.

Data processing system and method

A data processing system according to one embodiment includes first and second data storage devices having a storage medium capable of permanently storing data; a data holding device having a storage medium capable of storing the data at a higher speed than the first and second data storage devices; and a controller that determines the type of data to be processed, and, in the case where the data to be processed is structured data, stores the data to be processed in the data holding device, then, collectively, in the first data storage device, and, in the case where the data to be processed is binary data, stores the data to be processed in the data holding device and in the second data storage device.

Data processing system and data processing method

In one aspect, a data accumulation apparatus includes a script execution environment, an accumulation and retrieval unit accumulating data and performing retrieval on the accumulated data, a notification unit outputting notification in response to that data newly accumulated in the accumulation and retrieval unit matches one of conditions registered in advance, and a storage unit storing scripts and action correspondence information. The script execution environment has property of being capable of describing an instruction to perform data retrieval and an instruction to perform communication through the network, according to a script being executed. The data accumulation apparatus further includes a collection unit collecting data through the network and registering the data in the accumulation and retrieval unit, and a script execution unit executing, on receipt of the notification, a script associated with the matched condition according to the action correspondence information using the script execution environment.

Data accumulation apparatus, data accumulation method, and program

Data transmitted from an information transmission device can be stored in a distributed manner, without the need to duplicate or transmit/receive data among information storage devices. Under the control of a data write unit, end points to be assigned are determined in each of the information storage devices, based on the preset information indicating a correspondence between the information storage devices and end points assigned to the information storage devices. The data transmitted together with the identifier corresponding to the assigned end point is acquired from among the data transmitted from the information transmission devices, based on a first correspondence table stored in a shared setting storage unit for associating the end points with the identifiers of the types of data acquired by the end points, and the acquired data is stored in the data storage unit.

Distributed storage system suitable for sensor data

According to an aspect of the invention, a data processing apparatus is provided. The data processing apparatus includes a data processing unit. The data processing unit is configured to perform at least part of: preprocessing on a data processing request to a common database issued by one of a plurality of applications accessing the common database; and post-processing on a search result returned from the common database in response to the data processing request.

Data processing apparatus and data processing method

When data generated by devices () arrive in an order of time instants of generation of the data, the data are additionally described (written) to an actual data recording unit () in an order of arrival of the data, and, meanwhile, a time instant, at which the data additionally written to the actual data recording unit () is generated, a data size, and a position of postscript in an actual data file are additionally written, as index information, to an index file () having a file name corresponding to the actual data file in which the data is recorded.

Information accumulation apparatus, data processing system, and program

An RPC conversion processing system () that performs relaying between a first application () and second application () of different protocols. The RPC conversion processing system includes a first interface provider () connected to the first application and configured to provide a first interface for the first application, an RPC conversion relay function section (), and a second interface provider () connected to the second application and configured to provide a second interface for the second application. The first interface provider receives a request for processing an RPC from the first application. The RPC conversion relay function section converts the RPC into an RPC of the second application and outputs the RPC of the second application to the second interface provider, thereby relaying an RPC between the first application and the second application.
