Method and system for managing partitioned data resources

In accordance with an exemplary embodiment of the present invention, association forming entities are: a) maintained as objects in a like manner to the data objects being associated; and b) are themselves partitioned objects comprising two or more association fragments, each association fragment being mostly concerned with the interfaces to a particular data object participating in the association. In accordance with an exemplary embodiment of the present invention, each association fragment affiliated with a particular data object is stored in a location that enhances the ease of interaction between the association fragment and the data object. For example, where a first data object and second data object are maintained in data stores at some distance from one another, physically or logically, then a first association fragment will be located with or near to the first data object, and a second association fragment will be located with or near the second data object, at least within the same partition. This arrangement may be preferable because the volume of interaction between a data object and its respective association fragment may far outweigh the interaction needed between the two association fragments. This arrangement may also be preferable as the volume of interaction between a client application and both the data object and respective association fragment may exceed the interaction needed between the two association fragments. Some interactions will employ only one of the association fragments with the net result being a reduction in communications requirements and an improvement in performance. The present invention further provides for defining logical domains which are arbitrary and entirely orthogonal to partitions.

Distributed data storage system and method

A distributed data storage system and method comprising a highly integrated mass storage controller system permitting distributed management and control of data storage is disclosed. The present invention in some preferred embodiments permits mass storage media to be made available on a network in a fashion to permit global access, while automatically handling many high-level file access and data integrity/security/control functions normally associated with a host operating system. This integration and redistribution of functionality permits spatial diversification of data resources, automatic mirroring of data, fault isolation, data security, and a plethora of other control functions to be integrated into the mass storage device. This integration permits peer-to-peer communication between mass storage devices to both unburden the host data consumers but also isolate the data management functions from the data presentation functions normally associated with host systems. Exemplary embodiments of the present invention as applied to specific preferred system contexts include but are not limited to distributed data storage in a networked environment, brokered data access metering, database access/control, data backup, journaling, checkpointing, and automated software distribution.

Multi-source heterogeneous database fusion system and data query method thereof

The invention provides a multi-source heterogeneous database fusion system and a data query method thereof. The system comprises a database layer, a data fusion layer and a uniform application layer. The database layer is composed of heterogeneous databases and agencies of the heterogeneous databases. The data fusion layer is used for fusing information of all heterogeneous data sources, and is responsible for data access of the heterogeneous data sources and coordinating the information of all the data sources, and specifically comprises a metadata data base (DB), a metadata manager, a comprehensive wrapper, a mediator, an application layer access uniform interface and a heterogeneous database uniform interface. The uniform application layer is the user of the heterogeneous database fusion system and can have access to shared data resources of the heterogeneous databases by fusing middle layers. The multi-source heterogeneous database fusion system and the data query method of the multi-source heterogeneous database fusion system solve the problems in heterogeneous database fusion and overcome the defects of an existing database fusion technology. The system can conduct transparent query on all the heterogeneous databases on the condition that local databases are not affected, and the maintenance cost of the system is reduced.

Method for building cross-chain alliance among block chains and block chain cross-chain communication method and system

The invention provides a method for building a cross-chain alliance among block chains and a block chain cross-chain communication method and system. The method for building the cross-chain alliance includes: acquiring the communication requirements of various communication nodes in multiple block chains; using the nodes which belong to the communication requirements to build the cross-chain alliance, and configuring identity certificate and transaction certificate; building a cross-chain smart contract. The block chain cross-chain communication method includes: using the various block chainsin the cross-chain alliance to acquire a communication request, and building a node smart contract for each node; if the communication request is initiated, performing endorsement strategy verification on the communication request, performing total order signature verification and data consistency verification, and using the cross-chain smart contract to achieve node communication when the communication request passes the verification. By using the method to build the cross-chain alliance, cross-chain communication among different block chains is achieved, data resources on different block chains can be shared, and resource utilization efficiency is increased.

Data resource security control method in thin client mode

The invention belongs to the field of network security, and particularly relates to a data resource security control method in a thin client mode. The data resource security control method in the thin client mode comprises eight subsystems, namely the identity authentication subsystem, the remote application service subsystem, the security label subsystem, the file access control subsystem, the security communication subsystem, the security audit subsystem, the security storage subsystem and the management platform subsystem. Storage and control of files are mainly performed on a background server, the files are stored in different partitions according to user types or security levels of the files, the files are stored and protected, and a server side can not recognize the content of the files. When a user needs to have access to and process the files, the user logs in on a browser, identity authentication is conducted between the user and a server, and then file access connection is established. The files of a thin client are processed on the server side (provided by a physical application server or a virtual application server), no application or agent needs to be installed on the thin client, and interface interoperability is supported by related services released by remote application services.
