Problems solved by technology

[0005] First, the scalability is not good
Because the Schema format needs to be defined in advance, it is very inconvenient to add information of a new type of resource. For example, if a user wants to add information of a network resource to an MDS node, he must first modify the configuration file of the MDS node and add the information of the network resource. Schema and restart the server of the MDS node to make it effective, and then insert the information of the network resource
This process is very cumbersome, especially when the user wants to add the network resource information to another MDS node, the above work needs to be repeated again
[0006] Second, there is no synchronization
But for Globus, when the Schema definition or modification is made to the configuration file of an MDS node, it only takes effect on the MDS node, but not on other MDS nodes in the information service system. Therefore, after a certain period of time, each MDS node The Schema adopted on the Internet is likely to be inconsistent, resulting in the need to use different XPath query statements when querying for different MDS nodes, and thus causing obstacles to resource information sharing between MDS nodes
[0007] To sum up, grid information services require information processing systems and methods with good scalability and synchronization, but currently there is no technical solution that meets the above requirements

Embodiment Construction

[0029] see figure 1 , is a schematic diagram of the grid environment where the grid information model system of the present invention is located. The grid information model system 1 runs in the grid server 2, and communicates with a plurality of grid information nodes 31, 32, 33...3N through IP network connection.

[0030] The grid information model system 1 provides interfaces for adding, deleting, modifying and querying the above-mentioned grid information nodes, including administrator information service nodes, ie, end users, to uniformly manage grid information models in grid resources.

[0031] The so-called resource information model refers to metadata describing resources, that is, information describing resource information. For example, for the student Zhang San, the information is: 10003, Zhang San, male, 1982.01.01; for the student Li Si, the information is: 10004, Li Si, female, 1980.01.02, their information content is different, but both It is described from th...

Abstract

The invention discloses a grid information model system connected to external grid information node, which comprises: an interface, a statement interpreter to complete addition, cancel and modification or query information model operations, a relational database, and a synchronous processor to synchronize the database variation to opposite grid information node. It also discloses a method to modeling treat grid information, which comprises: the said interpreter analyzes command type; to addition, modification and cancellation commands, the interpreter modifies database; to modification and cancellation commands, the said processor also updates grid information node; to query command, it stores relational information. This invention realizes dynamic addition, modification and cancellation to grid information model, has no limit to stored resources information, and ensures model consistency.

Description

technical field [0001] The invention relates to a method for modeling grid information, in particular to a method for modeling grid information for dynamically updating resource information. Background technique [0002] With the increasing popularity and development of the Internet, the grid technology for the purpose of realizing resource sharing and collaboration in the wide area network environment has been vigorously developed. Therefore, as a basic component in the grid system, the grid information service system responsible for managing the resource information in the grid has increasingly high requirements for the effectiveness and convenience of its management. [0003] However, due to the heterogeneity and diversity of grid resources, the effective organization and management of all resource information has become the primary problem to be solved by each information service system in the grid world. [0004] Among the many information service systems, the most fam...
