Description
Technical field
The present invention relates to field of computer technology, particularly a kind of data deletion system, method and data delete center.
Background technology
Along with the development of computing machine, increasing application software is developed.In applied software development process and in the process of application software use, a lot of relevant data relate to deletion action, but in the application system that deleted data have likely been applied to other or scene, after such as commodity data produces, its relevant information, such as sequence information, enter library information and go out library information etc., other application system all can be used, data may cause other relevant application systems abnormal after deleting, so often need the checking procedure of a lot of data association messages when carrying out data and deleting, to ensure the application system relevant to other to impact.
Data be stored and follow-up use time, have two kinds of modes:
First kind of way: the relevant information of data uses same database, relevant information for data upgrades, the sequence information of such as commodity data, enter library information and go out the information tables such as library information often record and the unique identification of corresponding goods data in a database, the information such as the such as title specification of commodity data are when being presented to user, obtain by accessing database, if the commodity data that these commodity data tables are corresponding is deleted, then the attribute information such as such as trade name and specification etc. of this commodity data cannot obtain, and cause the disappearance of commodity data.
The second way: the different relevant informations of data use different databases, relevant information for data upgrades, and the sequence information of such as commodity data, enters library information and goes out the information tables such as library information often record and the unique identification of corresponding goods data in disparate databases.In this case, the information table of commodity data obtains rear unification by set form center from disparate databases to be provided, the information table of the commodity data stored in each database of Timing Synchronization of form center, then combine, when combining, if the commodity data of correspondence is deleted, then also can causes the disappearance of commodity data and the information table of this commodity data cannot be combined.
At present, the deletion mode of data has two kinds, and one is that physics is deleted, and data is directly deleted from database exactly and discharges the space that former data take; Another kind is that logic is deleted, and data are stamped disabled mark, can not delete from database, also can not discharge the space that former data take, data can be recovered after deletion at any time.
The deletion verification of data completes primarily of initiation data deletion side, initiating data deletion side needs the relevant information understanding deletion data to be applied to which application system side, and one by one confirm whether data are used by the inquiry database of application system side or server, if used, then the prompting used will be fed back by application system side, initiate data deletion root whether can delete according to prompting determination data, if the application system side that data are employed is many, then initiate the data side of deletion workload then very large, and need the logic understanding each application system side, an application system side is had to reckon without, then can cause the data exception of this application system side, being coupled between application system side with initiation data deletion side is deep, be unfavorable for application system side and expansion and the maintenance of initiating data deletion side.
To sum up, because the deletion verification of data completes primarily of initiation data deletion side, it needs the relevant information understanding the data of deleting to be applied to which application system side, and whether confirmation data one by one are used, and so just there is following shortcoming:
The first, if there is new opplication system side to employ the relevant information of data, but fail to give notice to initiation data deletion side, then cause due to deleting of data by mistake the relevant information of these data in this new opplication system side abnormal;
The second, if there is new opplication system side to employ data, initiating data deletion side needs update routine code, thus can access the deletion verifying work that this new opplication system side carries out data, is unfavorable for expansion and the maintenance of initiating data deletion side;
3rd, initiate the data side of deletion workload larger, arrange the function of each application system side of the relevant information of access application data thus the deletion carrying out data to each application system side verifies, maintainability is poor.
