Description
[technical field]
The present invention relates to a kind of database space management system, particularly a kind of management system that is applied to data in the automatic delete database.
[background technology]
Have some machinery and equipment in commercial production, this machinery and equipment can produce some some data about finished product after producing finished product, and these data are transmitted automatically with certain store path and are stored on the machinery and equipment server.General, this data volume is big, and more data are arranged is gibberish, and the data that produce as OMRON AOI machine comprise: finished product view data, finished product generation time data, finished product supplemental characteristic.Machinery and equipment will be stored lot of data on the server after long-term use, be a kind of challenge to the server of finite capacity.
Find that in the long-term production process only need to keep the view data of some finished products, other data are redundant data, the producer only wishes to keep view data after producing finished product.So just can the deletion data for the producer, but in delete procedure, to find each finished product to produce the file of data, and distinguish useful data and useless data, the workload of searching so for the user and deleting is very big, and machinery and equipment need be suspended use in delete procedure, get off to influence production output for a long time like this, delay the finished product shipment.If in delete procedure directly all data Delete Alls, like this in the test process afterwards because of no related data compares, in the bad tracing process of finished product, cause great inconvenience.
[summary of the invention]
The object of the invention is to provide a kind of database space management system, particularly a kind of management system that is applied to data in the automatic delete database.
The invention provides a kind of database space management system, this system comprises:
One starts module, and it is used to start this system;
One searches module, and it is used for searching the data that database will be deleted, and this is searched module and during data, judge that whether the data of searching are for wanting deleted data in searching database;
One removing module, it is used for deleting the data that will delete that above-mentioned database finds out;
One logging modle, it is used for writing down the information of the database data of a certain moment deletion.
Specifically, the described module of searching is carried out sequential search according to the path keyword of storage data and the temporal information of data storage in the database.
Specifically, the keyword of described data routing comprises storage area, machinery and equipment title, finished product title, and this is searched module and positions in conjunction with data in the described crucial word pair database.
Specifically, described logging modle recorded information be current deleted data time and routing information.
The present invention also proposes a kind of method of the SPACE/MA that is used to control database, and this method comprises the following steps:
(1) opens this system by starting module;
(2) search the information of deleting the last time of writing down on the module reading and recording module;
(3) search module and continue to search and want deleted data, and the transmission delete instruction is to removing module;
(4) removing module receives delete instruction, directly deletes the above-mentioned deleted data of wanting;
(5) judging whether to have deleted the data that will delete, is "Yes" as judged result, then enters step (6), is "No" as judged result, then returns step (3) and proceeds to search.
(6) time of logging modle record deletion data and routing information.
Compared with prior art, database space management system of the present invention is provided with one and starts module, when the machinery and equipment operate as normal, opens operation automatically on the backstage; This system is provided with one in addition and searches module, a removing module, a logging modle, make that whether data are for wanting deleted data in this system automatic judgment data storehouse, and directly delete, and when begin to carry out in the delete database data next time, can proceed the deletion action according to deleted data position last time.

Fig. 2 is a database space management method schematic flow sheet of the present invention.
[embodiment]
Join shown in Figure 1ly, be database space management system structural representation of the present invention.
The invention provides a kind of database space management system, particularly a kind of management system that is applied to data in the automatic delete database, in present embodiment, data are arranged according to the regular hour order in this database, and this system comprises:
One starts module 1, and it is used to start this system, and in present embodiment, this startup module 1 is provided with a timing unit, and it is used for opening and move this system automatically at setting-up time;
One searches module 2, it is used for searching the data that database will be deleted, this is searched module 2 and carries out sequential search according to the time of data routing of storing in the database and data storage, in present embodiment, the keyword in this path comprises storage area, machinery and equipment title, finished product title, this is searched module 2 and positions in conjunction with data in the described crucial word pair database, this searches module 2 in searching database during data, judge and whether search data for wanting deleted data, in present embodiment, search module 2 and set non-picture data for wanting deleted data;
One removing module 3, it is used for deleting the deleted data of wanting that above-mentioned database finds out, in present embodiment, data in these removing module 3 direct delete database;
One logging modle 4, it is used for writing down the database data message of a certain moment deletion, and in present embodiment, these logging modle 4 recorded informations are the time and the routing information of a certain moment deleted data.
Join shown in Figure 2ly, be database space management method schematic flow sheet of the present invention.The present invention also proposes a kind of method of the SPACE/MA that is used to control database, and this method comprises the following steps:
Step 100: on the timing unit of this system start-up module 1, set the opening time,, on timing unit, set every day in a certain moment and open this system in present embodiment;
Step 101: system opened automatically in the opening time of setting, and on the backstage, move, above-mentioned searching deleted information the last time that module 2 reads on the described logging modle 4 record, and in present embodiment, this searches time and data associated pathway that module 2 reads deleted data last time;
Step 102: above-mentioned search module 2 according to last time deleted data time and path continue to search the data that will delete, and the transmission delete instruction is to removing module 3, this delete command is searched the order of wanting deleted data that module 2 is judged for deletion, in present embodiment, this is searched module 2 and carries out sequential search according to time and path that data in the database generate, judge non-picture data for wanting deleted data, and should want the deleted data information transmission to removing module 3;
Step 103: above-mentioned removing module 3 receives above-mentioned module 2 delete instructions of searching, and directly deletes above-mentioned data;
Step 104: the described module 2 of searching judges whether to have deleted the data that will delete, in present embodiment, this is searched module 2 and judges whether the data that generate between rise time of data of deletion this moment and current time have deleted and want deleted data, as judged result is "Yes", searching module 2 and think to have deleted and want deleted data in the database, then enter step 105, is "No" as judged result, search module 2 and think that data need deletion in addition, then return step 102 and proceed to search.
Step 105: above-mentioned logging modle 4 writes down last deleted data time and routing information after removing module 3 has been deleted data, in present embodiment, the information stores of these logging modle 4 records is a text, the above-mentioned module 2 of searching is when searching data next time, directly read text file, the time and the routing information of the data of the last deletion of text file logging.
