Embodiment
Fig. 3 has shown the device of managing terminal data logging of the present invention, and terminal of the present invention can be that client shown in Figure 1 is a portable terminal, also can be server shown in Figure 1.
As shown in Figure 3, the device of managing terminal data logging of the present invention comprises: LUID distribution module, UUID distribution module and LUID and UUID mapping relations module.The LUID distribution module is used for distributing a local unique identifier LUID into each bar data recording of terminal; The UUID distribution module is used for distributing a Globally Unique Identifier UUID into the memory location of each bar data recording of terminal; Each bar data recording that LUID and UUID mapping relations module are used for being respectively terminal is set up the mapping relations of LUID and UUID; The Changelog module then is used for: 1) each deposit position in amendment record changelog file is hidden corresponding UUID respectively; 2) during the data recording asynchronous operation, LUID that use is set up and the mapping relations of UUID are revised the value of the amendment record item in the changelog file; 3) during data recording synchronous operation, the value of the LUID that use is set up and the mapping relations of UUID and changelog file modifying entry is searched and is treated the data in synchronization record.
Fig. 4 has shown LUID of the present invention and the UUID mapping relations figure that is generated by mapping relations module shown in Figure 3, wherein LUID44,85 and 100 is respectively that the LUID distribution module is three local unique identifiers (as positive integer) that the terminal data record distributes, such as 44 be about open * * the local unique identifier of the data recording of phone directory, 85 be about Lee * * the local unique identifier of the data recording of phone directory, 100 be about the king * * the local unique identifier of the data recording of phone directory.With LUID44,85 and 100 corresponding UUID1,2,3 be that the UUID distribution module is the globally unique identifier that the memory location of the data recording that LUID identified is distributed.
Fig. 5 a has shown the structure of an amendment record item of changelog file of the present invention, and it does not have the LUID in traditional changelog file modifying entry shown in Figure 2.Fig. 5 b has shown that UUID is hidden in the situation in the changelog file, because the changelog file is made of a rule amendment record item of orderly arrangement, therefore (its deposit position sequence number is corresponding to the byte sequence number of changelog for the deposit position of each bar amendment record item in the changelog file, for example, when entry length is 1 byte, then the sequence number of N deposit position is the N byte sequence number of changelog) can reflect the UUID of corresponding data recording uniquely, for example when amendment record item length is 1 byte, the amendment record item of the 3rd deposit position reflection UUID is the modification situation of 3 data recording.
The length of each amendment record item of the present invention is fixed, and is 1 byte such as regular length, or 2 bytes etc., this shows that the deposit position of each amendment record item depends on amendment record item byte length in the changelog file.Therefore the hiding relation of UUID in the changelog file is actually the deposit position determined according to the byte sequence number in the changlog file and the corresponding relation of UUID, is expressed as: the byte sequence number in the changlog file=(UUID-1) * amendment record item byte length+1.
If the regular length of each amendment record item is 1 byte, each amendment record item only takies a byte so, therefore the sequence number of amendment record item deposit position is equivalent to the byte sequence number of changelog file, be byte sequence number=(the UUID-1) * 1+1=UUID in amendment record item deposit position=changlog file, for example the 3rd byte sequence number of changelog file is equivalent to the sequence number of the 3rd deposit position, and making the sequence number of the 3rd byte of changelog file hide identifier is 3 UUID.
If amendment record item regular length is 2 bytes, each amendment record item takies two bytes so, the sequence number of its first byte=(UUID-1) * 2+1=UUID * 2-1.For example when UUID was 3, its sequence number of depositing first byte of amendment record item was 5, and the sequence number of depositing second byte of amendment record item is 6, made that sequence number is that to have hidden identifier be 3 UUID for the byte of 5 changelog file.
During the data recording asynchronous operation, the Changelog module utilizes the mapping relations of UUID and LUID to find the UUID of the data recording that is identified by LUID, follows the value of revising the current amendment record item on the changelog storage positions of files corresponding with the UUID that is found.Need to prove that data recording asynchronous operation of the present invention comprises: add or the modification data recording, and the synchronous successful subsequent treatment (below will illustrate) of data recording.
During to the synchronous operation of data record, the Changelog module reads the effective value of amendment record item in the changelog file and hiding UUID thereof, then utilize the mapping relations of UUID and LUID to obtain the data recording that LUID identifies, and then resulting data recording is carried out synchronous operation.
On the other hand, the method for managing terminal data logging of the present invention may further comprise the steps:
For each bar data recording of terminal (such as client or server) is distributed a local unique identifier LUID;
For distributing a Globally Unique Identifier UUID in the memory location of each bar data recording of terminal;
Each the bar data recording that is respectively terminal is set up the mapping relations of LUID and UUID;
Each deposit position in amendment record changelog file is hidden corresponding UUID respectively;
During the data recording asynchronous operation, LUID that use is set up and the mapping relations of UUID are revised the value of the amendment record item in the changelog file;
During data recording synchronous operation, the value of the LUID that use is set up and the mapping relations of UUID and changelog file modifying entry is searched and is treated the data in synchronization record.
During the data recording asynchronous operation, utilize the mapping relations of UUID and LUID to find UUID by the data recording of LUID sign, then revise the value of the current amendment record item on the changelog storage positions of files corresponding with the UUID that is found.Such as being under the situation of 1 byte in changelog file modifying entry length, when add a LUID=85 about Zhao * * phone directory recording the time, utilize the Globally Unique Identifier UUID=2 that figure can inquire its memory location that hints obliquely at of Fig. 4, the deposit position that obtains the changelog file thus is 2, thereby the value of the current amendment record item of the 2nd deposit position of changelog is revised as 1.
Data recording of the present invention successful subsequent treatment synchronously belongs to the data recording asynchronous operation, it comprises: for finishing the data in synchronization record, utilize the mapping relations of UUID and LUID to find UUID by the data recording of LUID sign, it is invalid then the value of the current amendment record item on the changelog storage positions of files corresponding with the UUID that is found to be revised as, be generally 0, to avoid down subsynchronous successful synchronously data recording.
During to the synchronous operation of data record, read the effective value of amendment record item in the changelog file and hiding UUID thereof, then utilize the mapping relations of UUID and LUID to obtain the data recording that LUID identifies, and then resulting data recording is carried out synchronous operation.
Below in conjunction with Fig. 4 to Figure 11 the characteristics of managing terminal data logging of the present invention are elaborated.
For the data recording item that is stored in terminal (such as, a cards folder in the mobile phone),
The present invention is provided with a LUID (Locally Unique Identifier), and local unique identifier, this LUID are unique in whole terminal, and are ever-increasing.Even add a deleted identical data record, the LUID that distributes for this new interpolation data recording also is inequality with original deleted LUID.
Except that LUID, the present invention also is provided with a UUID (Univeral Unique Identifier), and Globally Unique Identifier is identifying the memory location that these data are recorded in the database storing space., the corresponding UUID of data recording, the value of UUID is fixed, and is generally 1～MAXNUM, and MAXNUM is the storable dominant record item number of terminal database storage container.UUID is identifying the relative position of this data recording item in database, according to UUID, can find corresponding data recording content.
The present invention has set up the mapping relations of LUID-UUID shown in Figure 4, and such as mapping table, but its form is not limited to table.
In the LUID-UUID mapping table, dynamically corresponding the LUID and the mapping relations of UUID of same data recording, the pairing LUID of data recording that can find this UUID to store by current UUID; Can correspondence find its UUID by LUID, and find its memory location, take out data by UUID.
For example in Fig. 4, if know that the LUID of a data recording is 3, then the UUID that can find out this record by mapping table is 100, and promptly this record is stored in the 100th memory location of database; If know that the UUID of data is 1, i.e. record on memory location 1, then can find out its LUID by mapping table is 44.
Usually, the changelog file is made up of amendment record item one by one, each amendment record item, the information of representing data records (entity) to be modified.
Unique distinction of the present invention is:
1) the amendment record item is a regular length in the changelog file.
2) modification of each data recording is only unique corresponding to a changelog amendment record item, so the changelog file size is fixed, its value is the length of MAXNUM * amendment record item.
3) set up the mapping table of a LUID-UUID, can find LUID, also can find UUID. by LUID simultaneously by UUID
4) changelog file data entry does not adopt LUID, does not directly adopt UUID yet, and its amendment record item only is made up of " other guide " shown in Fig. 5 a, for example represents effective or invalid value to form.
Simultaneously, the UUID (information) of data is hidden in the position of changelog file modification entry, shown in Fig. 5 b.
As, when amendment record item length was 1 byte, amendment record item 4 was represented the 4th amendment record item in the changelog file, and then Dui Ying UUID is 4.When these data are operated, then can pass through UUID, or find LUID, its operation by UUID.
So, not only shorten the length (saved the ID byte number of each amendment record item, will significantly reduce the length of amendment record item, thereby saved the storage space of changelog) of amendment record item greatly; Simultaneously, the UUID Information hiding in changelog file itself, has not only been saved storage space, and can effectively position, greatly reduced the operation and maintenance complexity of changelog the amendment record item.
With the mobile phone terminal cards folder is example synchronously, supposes that mobile phone terminal database max cap. is 500 phone directories.The structure of amendment record item only contains the action type of the sign FLAG of regular length (such as accounting for a byte) as shown in Figure 9 in the Changelog file of the present invention.
Fig. 8 has shown the structure of amendment record item among traditional changelog, and wherein the structure of amendment record item comprises in the Changelog file: the LUID with 13 bytes; Contain the action type that indicates FLAG, be meant the operated type of phone book entries, as adding etc.Its value is: 0 representative is invalid, 1 representative interpolation operation, and 2 represent deletion action, and operation is upgraded in 3 representatives, and 1～3 all represents effectively, accounts for 4 bytes.So the data recording item length of traditional changelog is totally 17 bytes.
The structure of amendment record item structure and amendment record item of the present invention shown in Figure 9 is not difficult to find that the present invention shortens the length of amendment record item greatly among documents traditional changelog shown in Figure 8.
Figure 10 has shown one, and wherein grid illustrates that each amendment record item, its length are a byte by an empty changelog file behind the initialization operation, and its initial value is 0, and it is invalid to represent.
Fig. 6 has shown the flow process of renewal changelog file of the present invention, is used to illustrate an example of data recording asynchronous operation.With the phone directory recording that adds a LUID=100 is that example describes, and supposes LUID-UUID mapping table such as Fig. 4 at this moment, then:
1) inquires about its UUID=3 according to LUID;
2), search the position at corresponding amendment record item place: (3-1) * 1 (byte length)+1=3 according to UUID.
Directly find position corresponding among the changelog, the 3rd deposit position promptly shown in Figure 11.
3) revise at the 3rd deposit position (the 3rd entry place) of changelog file, action type is for increasing, and then its value is 1, and representative increases.
Fig. 7 has shown that terminal execution data recording of the present invention reads the flow process of changelog file when synchronous, and this flow process comprises:
1) traversal reads first, second amendment record item earlier as the changelog file of Figure 11.Its value is 0, and it is invalid to represent.
2) read the value of the 3rd entry, its value is 1, effectively.Then:
A) according to its position the 3rd byte, calculate UUID=(3-1)/1-1=3.1 length of representing changelog amendment record item wherein.
B), suppose still to be shown in Figure 1, then LUID=100 according to the LUID-UUID mapping table.
C) when synchronous, the phone directory of LUID=100 can be carried out synchronously.
The synchronous successful subsequent treatment of data recording belongs to the asynchronous operation of data recording, usually start this operation according to synchronous successful response signal, during such as the synchronous success response of data recording of sending when server about LUID=100, client is carried out following processing (referring to Fig. 6):
Inquire about its UUID=3 according to LUID;
According to UUID, search the position at corresponding amendment record item place: (3-1) * 1 (byte length)+1=3.Directly find position corresponding among the changelog, the 3rd deposit position promptly shown in Figure 11.
The 3rd deposit position (the 3rd entry place) at the changelog file is revised, and being revised as its value invalid is 0, so that avoid repeat synchronously next time.
In sum, the present invention has following technique effect:
The persevering sizing of changelog file, its size is the length of MAXNUM* amendment record item, promptly do not have the file size problem that increases without limitation, and maximum file size is also very little.
For example traditional changelog scheme changelog file increases along with the increase that is modified the record number, and its value is the length of X* amendment record item, and wherein X is the current record number that is modified; Changelog length of the present invention is the length of MAXNUM* amendment record item.
Such as, the terminal data storage capacity is 500, for length is the traditional scheme amendment record item of 17 bytes, the changelog file needs 500 * 17=8500 byte, and changelog file of the present invention only needs 500 * 1=500 byte, that is to say, under same storage space condition, when the amendment record number surpassed 30 (500/17=30) bar, this programme had a clear superiority in aspect storage space.
On the other hand, suppose that amendment record has M, synchronization server has individual and corresponding each server of N that one cover changelog is arranged.Then for prior art, in the time need making amendment to certain the bar entry among the changelog, its complexity is 0 (M*N), and all operations all is file operation.For this programme, because of changelog can navigate to certain amendment record very soon, need not the traversal formula and search, then its complicated operation degree is 0 (N).So this programme is very simple to the operation and maintenance of file.
In sum, because the present invention utilizes the mapping relations of IUID and UUID to manage amendment record item in the changelog file, therefore can reduce the length of changelog file greatly, thereby reduce file storage; In addition, the present invention hides relation by changelog storage positions of files and UUID, it is the corresponding relation of changelog file byte sequence number and UUID, office terminal amendment record or obtain the amendment record of LUID sign by deposit position, thereby greatly reduce the complicated operation degree of changelog, make whole changelog file operation and safeguard simplification.Particularly, for supporting and the system of a plurality of server sync that the present invention can greatly reduce complexity.
Specifically, the technique effect that file storage of the present invention is few and management complexity is lower is owing to following technical characterstic of the present invention:
1, the length of each amendment record item all reduces greatly;
2, each file only comprises the amendment record item of fixed number;
3, the value of at every turn upgrading the amendment record item such as does not need to search at operation.
Although above the present invention is had been described in detail, the invention is not restricted to this, those skilled in the art of the present technique can carry out various modifications according to principle of the present invention.Therefore, all modifications of doing according to the principle of the invention all should be understood to fall into protection scope of the present invention.
