Description

A kind of method and system of distributed data retrieval result Pagination Display
Technical field
The present invention relates to information technology field, more particularly to a kind of method of distributed data retrieval result Pagination Display and System.
Background technology
Internet development is rapid, it has also become the important component of people's life and the important load of human civilization communication development Body penetrates into economic, politics, culture, social life various aspects, changes the manner of intercourse and the mode of thinking of people.No matter It is either in social life field in industrial circle, the change that internet gives people is huge.
As the core of internet data record, database also penetrates into the various aspects of society, is widely developed And application.Database is the set for the related data got up according to certain structure and regular weaves, is from the overall point of view It establishes, tissue, description and storage is carried out by certain data model.Its structure based on the associate naturally between data, so as to All necessary access paths are provided, and data have whole structuring no longer for a certain application, but towards full tissue Feature.
Database be used for data storage and processing, storage be belong to enterprise, operating divisions, organization and individual it is related The set of data is the general data processing system of a unit or an application field.Data in database are for crowd Multi-user shares its information and establishes, and has had been extricated from the limitation and restriction of specific procedure.Different users can be by each From usage use the data in database；Multiple users can simultaneously in shared data bank data resource, i.e., different use Family can access the same data in database simultaneously.Data sharing not only meets each user and the information content is wanted It asks, while also meets the requirement of each user-to-user information communication.
Database is important e-sourcing, is the information technology for adapting to internet development, has the characteristics that：
1), the structuring of data.Data in database are not disorderly and unsystematic, not the least concerned, they have certain Institutional framework, belong to identity set data have similar feature.
2), data tool sharing.Between each department of a unit, there is substantial amounts of duplicate messages.Use number It seeks to be managed collectively these information according to the purpose in storehouse, reduces redundancy, each department is made to enjoy identical data jointly.
3), the independence of data.The independence of data refers to the independence between data record and data management software.Data And its structure should have independence, without that should go to change application program.
4), the integrality of data.The integrality of data refers to the correctness for ensureing data in database.It may cause data There are many incorrect reason, and data base management system manages them by being checked data character.
5), the flexibility of data.Data base management system is not that data are simply accumulated, it is in the base of recording data information There is many management functions, such as input, output, inquiry, edit-modify on plinth.
6), the security of data.According to the responsibility of user, the people of different stage has database different permissions, number It can be ensured that the security of data according to base management system.
Reaching unprecedented height with spread speed as information content increases, the quantity of information data is increasing, Higher requirement is proposed to the storage of data.In order to tackle the challenge that data storage proposes, distributed storage is to slow down data Store the effective ways of pressure.Distributed memory system is that data are disperseed the storage side being stored in more independent equipment Formula.Traditional network store system stores all data using the storage server concentrated, and storage server becomes system performance Bottleneck and the focus of reliability and security, it is impossible to meet Mass storage application needs.Distributed network storage system System uses expansible system structure, shares storage load using more storage servers, is positioned and stored using location server Information, it not only increases the reliability, availability and access efficiency of system, is also easy to extend.
With the extensive use of database technology, give people door and acquisition useful information is selected to bring ratio in information ocean The difficulty of bigger in the past.In information-intensive society, retrieval technique is more and more important for effective application of data, is mainly reflected in：
1), information retrieval technique can quickly search required information.Efficient information retrieval technique can save the time And cost, required information is accurately and rapidly obtained, working efficiency is improved, accomplishes to get twice the result with half the effort, realize the effective of information resources It utilizes.
2), efficient retrieval technology can systematically understand the accumulation of existing data in time, and it is newest dynamic to grasp business State and development trend make correct decision-making in due course, and carried out work is made to obtain most fast, most effective progress.
3), efficient retrieval can hold newest information in time, promote continuing to bring out for new business and application.
4) science decision, is contributed to.With the high speed development of modern information technologies, the electronization of information resources, diversification And the networking of service condition has become reality.Either country, department or enterprise will all rely more heavily on data Etc. the rapid exchange of information, propagate and utilize.Intellectual technology has become the means of policies.Knowledge and information have become Science, democracy, the source of Rational Decision.And information retrieval then be obtain information important channel, be science decision necessity before It carries.
Existing Distributed Database Searching technology is mainly that the technical side of database retrieval is carried out to cluster server Case, and the function of distributed data base is also based on to complete, search function and the scope of application are suitable for limited applied field Scape can not meet the application demand under Distributed Storage variation environment.Need effect of the optimization to distributed data retrieval Rate, to adapt to be widely applied scene.
