Said system includes an apply server multiple customer end computers and a local database. The customer end computer are used to provide an interactive user interface for the user to design information download conditions, the applier server is for downloading necessary information from remote database and displaying its download result by the customer computer, the local database storing information downloaded by the server.

Description

Data is downloaded the breakpoint transmission system and method
[technical field]
The present invention relates to a kind of data downloading system and method, particularly relate to a kind of data and download the breakpoint transmission system and method.
[background technology]
Along with the development of network transmission technology, most of Internet service provider all is give information inquiry and a download function of user, and the user can transmit data mutually by network on the network, also can directly download data from some network information service merchant's database by network.
When users from networks is obtained required information, many information sites query function of giving information.The user can search for needed data by setting querying condition, clicks the title of a certain Query Result or intersecting chain then and fetches and check or download its content.The general information website can only allow the user once to download one piece of content when download function is provided, and can not download the data that all satisfy condition automatically according to the querying condition that the user sets.User such as need are downloaded all data that satisfy condition, and can only download piece by piece artificially.Especially when the data quantity of required download is very big (as some data is to preserve with image file, and once can only download one page), this will expend the user and finish this download work a large amount of time.If situations such as network interruption are downloaded and can be finished automatically, need to the data downloaded carry out repeated downloads when downloading with similarity condition next time, causes user time and waste of network resources.
China national Department of Intellectual Property on October 29th, 2003 disclosed 1452095A patent application case name be called " data automatically download system and method ", a kind of download condition that can set according to the user is provided, automatically download the system and method for qualified data by network, this technology is before data is downloaded, can the self-verifying local data base, to avoid that existing data is carried out repeated downloads.But this technology is when checking local data base, needing to meet the data of storing in the data header list of download condition and the local data base compares, if the data quantity of having downloaded is huger, especially some data need be opened page by page, could compare with the data header list then, such comparison will spend a large amount of time of user, and take Internet resources for a long time.
So need being provided, a kind of data downloads the breakpoint transmission system and method, it can check local data base by elder generation before the network download data, to avoid that existing data is carried out repeated downloads, when checking local data base, do not need to compare the taking of time of downloading with the minimizing data and Internet resources with meeting the data of storing in the data header list of download condition and the local data base.
[summary of the invention]
Fundamental purpose of the present invention is to provide a kind of data to download the breakpoint transmission system and method, it can check local data base by elder generation before the network download data, judge whether to exist breakpoint information, if there is breakpoint information, then the position from breakpoint begins to download data, with the time of minimizing data download and taking of Internet resources.Above-mentioned breakpoint information refers to last record of Download History table.Above-mentioned Download History table is used to write down the title and the sequence number of each data of downloading.The position of the sequence number representative of above-mentioned breakpoint information is the position of breakpoint.
The invention provides a kind of data and download the breakpoint transmission system, it can judge whether to exist breakpoint information by local data base by checking earlier before the network download data, if there is breakpoint information, then the position from breakpoint begins data download.This system comprises an application server, a plurality of client computer and a local data base.Client computer is used to provide an interactive user interface, downloads condition so that the user is provided with data, and above-mentioned data download condition comprises contents such as the data address, data keyword, time span of required download.Application server is used for downloading qualified data from remote data base, generates tabulation of date and Download History table, and shows its download result by client computer.Above-mentioned tabulation of date is used to write down the title and the sequence number of the data that meets the download condition, and above-mentioned sequence number refers to the position of a document in meeting all data of same download condition.This application server comprises a condition acquisition module, is used to obtain the data download condition that the user is provided with; One data download module is used for downloading qualified data from remote data base, and generates tabulation of date and Download History table; One downloads the record sheet judge module, is used for judging whether local data base exists the Download History table that meets above-mentioned download condition; One breakpoint acquisition module is used to search last record of above-mentioned Download History table, and obtains its sequence number, and the position of this sequence number representative is the position of breakpoint; One downloads the judge module that finishes, and is used for the tabulation of date stored according to local data base, judges whether all qualified data have been downloaded to finish.Local data base is used to store data, tabulation of date and the Download History table that application server is downloaded.
The present invention also provides a kind of data to download breaker point continuous transmission method, and this method may further comprise the steps: (a) obtain the data download condition that the user is provided with; (b) generate tabulation of date; (c) judge whether to exist the Download History table that meets above-mentioned download condition; (d) if there is the Download History table that meets above-mentioned download condition, then search last record of above-mentioned Download History table, and obtain its sequence number, the position of this sequence number representative is the position of breakpoint, begin data download from the position of the breakpoint of above-mentioned tabulation of date, and the title and the sequence number of this data is recorded on the Download History table; If there is no breakpoint information begins to download from the first stroke data of above-mentioned tabulation of date, and the title and the sequence number of this data is recorded on the Download History table; (e) judging whether the data meet above-mentioned download condition is downloaded finishes; (f) if data is not downloaded to finish, then download another document, and the title and the sequence number of this data is recorded on the Download History table; If downloading, data finish, then process ends; (g) repeating step (e) is to (f), and the data content in above-mentioned tabulation of date under all titles has all been downloaded and finished.
Utilize the present invention, the data that the user can need by network download, and can not carry out repeated downloads to the data that is stored in the local data base, thus saved the time that data is downloaded, reduced taking of Internet resources.
