Embodiment
The object of this invention is to provide a kind of method of the data syn-chronization based on timestamp, the method efficiently, accurately can carry out data syn-chronization, improves system performance.
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Origin system hereinafter refers to that data segment occurs to be changed, and initiates the system of data syn-chronization operation, and every what have this function is exactly origin system; Goal systems refer to response synchronous operation carry out data syn-chronization operation, the system of Update Table section, every have this can be exactly goal systems.Origin system and goal systems also can be relative.
Please refer to Fig. 1, the process flow diagram of the method for the data syn-chronization based on timestamp that Fig. 1 provides for the embodiment of the present invention; The method can comprise:
Step s100, change the content of the first data segment selected;
Wherein, wherein, according to user operation, or need to carry out the data segment that changes during system cloud gray model, the content of this data segment to be needed according to user or the pre-defined rule of operation of system program changes over the content of needs.
Here the first data segment is referred to as, and namely need to need to change at origin system and goal systems system, namely the data segment completing data syn-chronization is referred to as the first data segment simultaneously.Namely this data segment needs to carry out synchronized update.
Step s110, to arrange the synchronous regime field of carrying in described first data segment be represent preset value to be synchronized, and the timestamp of data signature field;
Wherein, a lot of field can be comprised in first data segment, wherein there is the field that represents this data segment sync state, here synchronous regime field can be referred to as, here preset value is represent that this data segment has changed to need to carry out synchronous value, if the data class signal of such as this field is Boolean type, just can specify that 0 for representing that this data segment needs to upgrade in systems in which, 0 for representing that this data segment does not need to upgrade; Vice versa.
Can also have and represent the field such as data signature field of Data Update time, by distinguishing the content whether synchronous data segment contents is the latest update time update time of recording data segment.Prevent this data segment to upgrade several times, and goal systems does not obtain the phenomenon of the content of up-to-date data segment.
Step s120, to goal systems send described first data segment, revise the reference content of the second data segment as described goal systems, described first data segment and the second data segment mark match;
Wherein, after the synchronous regime field in the first data segment being set, send described first data segment to goal systems.
Goal systems is after obtaining described first data segment, and can find according to the mark of described first data segment the second data segment identifying and match within the system, also namely these two data segments are same data segments, are identified by data segment.After goal systems finds the second data segment, consistent with the first data segment by described second data segment being changed over content by the data content of contrast first data segment and the data content of the second data segment.Namely the data syn-chronization to the first data segment and the second data segment is completed; If the first data segment is here the data segment changed in general reference institute active system, then according to described first data segment contents by after described second data segment contents update all, then also namely complete the Data Update of system.
Thus also can see, such data-updating method is more efficient, because be only the Data Update of carrying out for the data segment changed, the update method of this increment type reduces the work such as a large amount of Data Comparisons, can significantly reduce expending of system resource, such as CPU, internal memory, Internet resources etc.Thus the performance of system can be improved.
Step s130, receive described goal systems feedback amendment acknowledge message;
Wherein, when origin system receives the amendment acknowledge message of described goal systems feedback; Also the message of the content having upgraded the second data segment is namely confirmed.
Step s140, the timestamp in this first data segment in the timestamp in described first data segment and database to be compared;
Wherein, here be relatively that after synchronous, mark is set to again " synchronous " in order to this mark after preventing data modification from upgrading is set to " not synchronous ".In data synchronization process, a time interval is marked with to writing back " synchronous " from reading data, if data have retouching operation in interval time, before being modified in, write back after " synchronous " be marked at, this retouching operation will ignore by data synchronization process next time, there is origin system and the inconsistent problem of goal systems data.
Step s150, when comparative result is consistent, arranging the synchronous regime field of carrying in described first data segment is represent synchronous preset value; When comparative result is different, the synchronous regime field of carrying in described first data segment does not change.
Wherein, origin system also needs the value of synchronous regime field in described first data segment to change into be expressed as synchronous preset value.Such as the value of synchronous regime field is set to 1, then represents that this data segment has upgraded and synchronously complete.
If comparative result is inconsistent, then illustrate and carried out again revising upgrading in this data afterwards, therefore, synchronous regime field can not be revised as synchronous regime, after needing to wait until that the content of the data segment revised afterwards also completes by goal systems, namely until the time consistency of timestamp record time, can carry out arranging the synchronous regime field of carrying in described first data segment is represent synchronous preset value.
Therefore, service time of the present invention stabs as data signature, unique identification data.When the data of a system change, modification time stamp field value, and stamp " not synchronous " mark, represent these data be modified but non-synchronized update to another system; System obtains only to be stamped the data that " not synchronous " mark and is transferred to another system and deals with; After another system process completes, return the result of " processed "; Original system is according to the result returned, if the timestamp of data does not change, data is stamped " synchronous " mark.
Based on technique scheme, the method of the data syn-chronization based on timestamp provided by the present invention, data segment after changing uses synchronous regime field to mark by the method, the system that eliminates needs all data to carry out the process such as contrast, finds delta data section in the process of carrying out data syn-chronization; Effectively can save system resource like this, save the processing time; A time course is needed again owing to carrying out data syn-chronization between system, therefore may occur within this time period that the data of a data segment change twice, and goal systems only to front once upgrade carry out synchronous, the renewal of this data segment in origin system once after miss out; Therefore may there is the problem of accurately not carrying out data syn-chronization, not only there is in the present invention synchronous regime field also there is data signature field, utilize the method contrasting update time to judge it is enough as latest update data, prevent error situation.The method efficiently, accurately can carry out data syn-chronization, improves system performance.
