As shown in Figure 3, be the process flow diagram of the first preferred embodiment of date storage method of the present invention.In this preferred embodiment, according to different demands, in this process flow diagram, the order of step can change, and some step can be omitted.
Step S11, receiver module 100 receives the file data that an electronic installation 5 transmits, and wherein, described file data comprises the significance level grade of the effective duration of one or more significance level and the file data corresponding to the effective duration of each significance level.
Step S12, according to the grade of the file data of the effective duration of the significance level of described file data and correspondence, judge module 101 judges whether this file data can be deleted at any time.As mentioned above, each file data of each electronic installation 5 is assigned the grade of the file data that the effective duration of one or more significance level is and the effective duration of each significance level is corresponding.When the effective duration of significance level of described file data is from (0 ~ ∞), namely any time from storing, the grade of corresponding file data is D, namely file data is inessential, can delete at any time, then judge module 101 judges that described file data can be deleted at any time, and perform step S19, removing module 102 deletes described file data.When cannot the deleting at any time of described file data, perform following step S13.
Step S13, judge module 101 judges whether the significance level grade of described file data is A, and namely whether described file data is very important data.When the significance level grade of described file data is A, perform step S14, described file data is stored in the first database 2 and the second database 6 by memory module 103, then continue to perform step S18, logging modle 104 records the transformation period of the described significance level grade of described file data.When the significance level grade of described file data is not A, perform following step S15.
Step S15, judge module 101 judges whether the significance level grade of described file data is that B judges whether described file data is important data.When the significance level grade of described file data is B, perform step S17, described file data is stored in the first database 2 by memory module 103, and then continue to perform step S18, logging modle 104 records the transformation period of the described significance level grade of described file data.
When the significance level grade of described file data is not B, then the significance level grade of described file data is C, and namely described file data is general data, and perform step S16, judge module 101 judges that whether the storage space in described first database 2 is enough.When the storage space in described first database 2 is enough, perform step S17, described file data is stored in the first database 2 by memory module 103, and then continue to perform step S18, logging modle 104 records the transformation period of the described significance level grade of described file data.When the memory space inadequate in described first database 2 is enough, perform step S19, file data described in removing module 102.
In the present embodiment, whether described receiver module 100 can be greater than preset value and judge that whether the storage space of described first database 2 is enough according to the storage space in described first database 2.
As shown in Figure 4, be the process flow diagram of the second preferred embodiment of date storage method of the present invention.In this preferred embodiment, according to different demands, in this process flow diagram, the order of step can change, and some step can be omitted.
Step S40, when the transformation period of the significance level grade of certain file data in the first database 2 arrives, judge module 101 judges whether the significance level grade of described file data is changed to B from A, namely from the data that very important data variation is important.
When the significance level grade of described file data is changed to B from A, perform step S41, the significance level grade of described file data is updated to B by update module 105, and then perform step S42, removing module 102 deletes the described file data in the second database 6.
When the significance level grade of described file data is not be changed to B from A, perform step S43, judge module 101 judges whether the significance level grade of described file data is changed to C or B from A and is changed to C, is namely changed to general data from very important data or significant data.
When the significance level grade of described file data is changed to C or B from A to be changed to C, perform step S44, judge that whether the storage space in described first database 2 is enough.When insufficient memory in described first database 2, perform step S46, removing module 102 deletes the described file data in the first database 2.When the storage space in described first database 2 is enough, perform step S45, the significance level grade of described file data is updated to C by update module 105.
When the significance level grade of described file data is not be changed to C from B, then the significance level grade of described file data is changed to D or B from A to be changed to D or C and to be changed to D, namely be changed to the data that can delete at any time from very important data, significant data or general data, then execution step S46 removing module 102 deletes the described file data in the first database 2.
It should be noted last that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to above preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not depart from the spirit and scope of technical solution of the present invention.
