501st, the first inquiry request for carrying benchmark event identifier is sent to database, so that the database root is according to institute State benchmark event identifier and determine that object event identifies, target data mark corresponding to the object event mark is searched in event table Know and sent to the equipment, wherein, the benchmark event identifier is used to reflect in the equipment data message preserved, institute Object event is stated to identify for reflecting unsaved data message in the equipment.

In the present embodiment, event table and data message table are stored with database, system performs data manipulation and produced Data message recorded by the two tables of data.Wherein, event table is used in record system what is occurred Data manipulation event, data message table are used for being produced in data manipulation event accordingly record system because performing data manipulation All data messages.

In event table, the mapping relations between event identifier and Data Identification can be specifically recorded.For example, in event table In be that each data manipulation event for occurring sets a list item in system, the list item includes being used to identify the data manipulation The event identifier of event and the event information for describing the data manipulation event, data mark is included in the event information Know, the Data Identification is used to identify data message caused by the data manipulation event.

It is understood that except Data Identification, the event information can also include other and be used to describe the data manipulation The information of event.As a kind of example, in the system as shown in fig. 3, the event information for example can be including " task 1 is added to In client executing server 1 ", " increase client executing server 1 is into control server " etc..

In some embodiments of the present embodiment, event identifier, event type, number can be specifically recorded in event table According to the mapping relations between mark three.For example, in event table in the list item of a data Action Events, including data behaviour Make event identifier, event type and the event information of event.Included in the event information and be used to identify the data manipulation event The Data Identification of caused data message.The event type represents the type of the data manipulation event.As a kind of example, scheming In system shown in 1, the type of data manipulation event can for example include " newly-increased task ", " newly-increased client executing clothes Business device " etc..

In data message table, the mapping relations between data message can be specifically identified with record data.For example, in number According in information table be system in caused by each data message set a list item, the list item include the data message and For identifying the Data Identification of the data message.

In the present embodiment, data manipulation can for example include the operation of increase data, delete the operation and modification of data The operation of data.Each data manipulation that system performed may be regarded as an event.In systems, data manipulation Event can be identified by event identifier.Each the data manipulation event occurred in system has an event mark Know, also, the event identifier of each data manipulation event is different, so, event identifier can be played and identified and distinguish not With the effect of data manipulation.As a kind of example, for a data Action Events, its event identifier can be a volume Code value, the encoded radio can represent the appearance order of the data manipulation event in systems.For example, go out for first in system Existing data manipulation event, its event identifier can be encoded radio " 1 ".And for example, grasped for the data of second appearance in system Make event, its event identifier can be encoded radio " 2 ".

In addition, in systems, data message can be identified by Data Identification.In system because perform data manipulation and Each caused data message has a Data Identification, also, the Data Identification of each data message be it is different, this Sample, Data Identification can play a part of identifying and distinguish different pieces of information information.

When implementing data syn-chronization, the equipment can generate the first inquiry request for carrying benchmark event identifier And sent to database, the benchmark event identifier can reflect the data message preserved in the equipment.Database response In receiving the first inquiry request, benchmark event identifier can be obtained according to the first inquiry request.According to the benchmark event identifier, Determine that object event identifies in all event identifiers that database can record in event table, object event mark is to use In the event identifier for reflecting unsaved data message in the equipment, specifically, object event mark is target data The event identifier of Action Events, data message caused by the target data Action Events are not preserve currently on said device Data message.After object event mark is determined, database can be according to the mapping relationship searching recorded in event table Go out target data mark corresponding to object event mark, and the target data found out is sent to the equipment and is identified.

In some embodiments of the present embodiment, database, can be by target after object event mark is found Event identifier sends jointly to the equipment with Data Identification.Even, database can be by object event mark described in event table Mapping relations where knowing all are sent to the equipment, including object event mark and its corresponding object event information, target Event type etc..

It should be noted that the determination identified according to benchmark event identifier to object event, can there is a variety of implementations.

As a kind of example, the reference data Action Events for being used to identify for benchmark event identifier, reference data behaviour It is all data messages that the equipment has preserved to make data message caused by event, is identified for object event for marking The target data Action Events of knowledge, data message caused by the target data Action Events are unsaved in the equipment All data messages.Specifically, the equipment can record when preserving data message caused by each data manipulation event The event identifier of the data manipulation event.If desired data syn-chronization, all event marks that the equipment can be currently to have recorded Knowledge is used as benchmark event identifier, and the first inquiry request for carrying benchmark event identifier is sent to database.Database response in The first inquiry request is received, the thing for being not belonging to benchmark event identifier can be searched in the currently stored event identifier of event table Part mark identifies as object event.

As another example, the event identifier of data manipulation event is particularly for representing data manipulation event in system In appearance order coding, that is, the benchmark event identifier be for representing reference data Action Events in the system In appearance order the first coding, the object event is identified as representing the target data Action Events in the system Second coding of the appearance order in system, wherein, the second coding is more than the first coding.It is used for what is identified for benchmark event identifier Reference data Action Events, the reference data Action Events are the numbers corresponding to the data message preserved in the apparatus According to the event finally occurred in Action Events, in other words, the reference data Action Events are for producing in the equipment The event finally occurred in all data manipulation events of all data messages preserved, that is, for producing described set In all data manipulation events of all data messages preserved in standby, the event identifier of reference data Action Events is coding Value maximum.Specifically, the equipment can record the number when preserving data message caused by each data manipulation event According to the event identifier of Action Events.If desired data syn-chronization, the equipment can be in all event identifiers currently recorded Choose encoded radio maximum one is used as benchmark event identifier, and the first inquiry for carrying benchmark event identifier is sent to database Request.Database response can search coding in receiving the first inquiry request in the currently stored event identifier of event table Value identifies more than the event identifier of benchmark event identifier as object event.
