This method requires the connection between the browser and the backend system. Java service code (10) adds J to generate different extensions and different ^e, letS) „^^ava4;^ communication officer 403 controls the message to and from the mobile device, for convenience 101 403 107 l Ζ^ί^ΐ: ^(TCP) ° and the state 403 receives the personal digital assistant 1〇1, soil; call, and resolves the remote program call string stream, the stream stream parameter

A suitable local procedure for converting the lean parameters. The result of the call generated by the remote program is stored in the output parameters of the data structure. The communication manager 403 is connected to a replication manager milk and a second manager 4〇7. The copy manager 4〇5 controls the data synchronization between the two-way data between the clients and the V, ^ ΐ assistant 1〇1 and the server 107. In addition, Copy Manager Transaction Control's Transaction Transaction Control can detect and resolve different customers. Connected to the replication manager 4〇5 is the primary domain tube 9, which is as follows. Write, ^^, can be solved in the following four methods. These four methods are “last written in the day-to-day stipulations, based on values, and “based on time stamps and values,” as detailed below:

Fine #υ,^ί彳^Write" touch the solution towel, write the last value of the 4 library will become the object n, ^ class method is suitable for those situations that are extremely unlikely, that is, many people want to update the same -^ This will create a problem, that is, if the previous modification was made offline, and it will not be copied until after the modification is made, the previous-time modification will cover the next modification. | (2) In the "value based" method, if the "old value" of the personal digital assistant 1〇1 matches the current value of the server 107, the server 1〇7 accepts the modification. (1) In the "time-based indication" method, if the modified time indication is greater than (in time later than) the current time indication of the object in the server 107, the modification is accepted. The premise of this method is that the clock of the personal digital assistant 101 is synchronized with the clock of the server. (4) In the conflict resolution method based on the day-to-day display and value, the modification time indication provided by the personal digital assistant 1〇1 13 1260139 must be later than the server provided by the personal digital assistant 101. "The old value, the value must match the server. These conditions ensure that the modification is recent and that the current representation of the object in f107 is made in the value phase. Note that if you know that the servo library 107's poor library can manipulate the object two-two library label, then the repair time, 1 in the object layer) during the update operation, will be stored for system management. Inspected. The system administrator can determine whether a particular modification should be accepted in a case-by case. The table manager 407 manages two graphs m 1

Item: 1 The relationship between the feeding machine 107 and the main assets stored in the data storage 417, and the chart of the f library. Of course, as in the above picture =, the $ sample 'master database and the memory 417 need not necessarily be on the feeding brother 107, but you can be in the computer equipment 1〇9 and lu one of the two 1〇7 through the network 121 access. The data structure of one of the second charts in the chart manager 407. When the data is retrieved from the ^ database, the information is extracted from the data in the chart _ _ ‘ =, and the extracted information is transmitted to the pass = Lili 2 = 2 iirr01. The chart manager 407 also has an additional secondary chart for extracting information from other mobile devices, such as the laptop 103. Save, 35==1 It is more effective to provide a copy of the data request from the personal digital assistant 101 before the data object is extracted from the master database. The purpose and power of caching is well known to those in the field of pens.

The total mining database interconnect (〇DBC) connection manager 413 (hereinafter referred to as the 0DBC connection and the chart manager 407 for communication connection. In addition to the person skilled in the art 1 connection pool semces context services} connection manager 413 An ODBC connection is established between the data access manager 415 and the chart manager 407 to obtain and return an open connection from the 0DBC connection pool to return all resources. The C connection manager 413 also handles connection failure and communication. The data access manager 415 controls access to the data store 417. In this specification, the lean memory 417 refers to the "remote, the data store, and the data store on the personal digital assistant 1〇1 refers to" Local "data storage." "Local" and "Remote," are specified for simplicity only. Data storage 14 1260139 Storage 417 may also be referred to as a local device or may be referred to as a remote data storage. Also & The data storage on the mobile computer device is a matter of f, that is, the two data storage devices are not resident in the same device, and the data is only based on such a business database management, 11 again. The specific details of the poor material access manager 415 processor 415 are familiar to those skilled in the art. The data access pipe technology is familiar to those skilled in the art. It is not important, and should also be known as the technical domain. Orchestration to enable the server program, such as database management system - collection and distribution to reduce the data type for specific attributes: it is a logical representation of the relevant information. Each object 'person: only two; .:: Niu Ye

Such as the action of Lei early business 孜 ^ bad hundred /, the object related to the poor material will also be the steam bank shooter business spear force application private order action hospital application 32 行动, mobile object * application private order 330 and mobile financial application 3 A given animal has a collection of domains corresponding to it. Applications such as 1 brother-picture not = If the 'Mobile Hospital Application 32' is available = the program 3ω, including product items. Specific procedures 1 , 42 ^ 3 are all in the domain manager, such as domain manager 421, domain manager 2 422 and domain lie cry 2 423 objects need different types of operations, so each - domain manager ^

Series 433 and so on. The domain managers 421 to 423 pass the data access manager 415 = to extract messages related to their respective objects. Each domain manager 421 ~ 423 = related domain control points. Such as search, add, update and delete, etc. to complete the business. Logic 431 ~ 433 for the customized domain, so that each special 2 iii can be mixed enough. Business money series 431 ~ 433 can also Including Lin to resolve data conflicts In order to prevent unnecessary software copying, all the common functions of domain managers 421 to 423 are concentrated in the primary domain manager 4〇9. The primary domain manager 4〇9 is a basic object, domain/management crying 4= 423 can inherit some attributes and methods from it. σσ 苐5 is a flow chart of the data management program 500 on the client mobile computer device, such as the personal digital assistant 101. The process begins at the beginning step 5〇1 Then, the transaction initialization step 15 1X60139 Γ, the user of the personal digital assistant 101 in '=^7? performs some actions to process the data. For example, the salesperson of the 101 can receive the purchase specific baseballization from the customer, The stock quantity is represented by the database on the server 1〇7. The second is synchronized by the central database of the server, or it can be omitted. Of course, once the inventory of the baseball is rounded up, local The information is that the local tribute library and the central database are not synchronized with each other. The data creation and update step, step 507 [Procedure 5 〇〇 资 资 t 新 新 新 新 新 新 新 新 新 新 新 新 新This is not the case, but if the information generated or received has not changed

The system + library, or if: the poor material is marked "no storage" (explained below), then control step 507 jumps to the end step 523, and the transaction process ends. If it is updated, go to #前接步骤5G9. In this step, the routine 500 determines if there is a current dynamic connection between the assistant 101 and the feeder tear. If no foi' is inserted into the sync sequence step 511, at this step, the data is placed in the personal digital assistant as "ίί 4 those pending transactions are stored here. In addition, the status of the data is set to *w. If the program determines in step 509 that the personal digit = the rational 101 and the feeding device 1 〇 7 are currently connected, the flow will go to the synchronization step. The second coarse fft is 5 〇 9 is inserted. Both the synchronization sequence and the synchronization in step 513 involve the transformation of the format into a format suitable for transmission, such as generating the content of the remote program call (the method of the number Wx and the basis of the generated (four) content and in the steps The data of the reduction and decrease of 5〇3 is δίΐ. In order to achieve correct and effective synchronization, the program 5〇〇 assigns the following resources to each object·· U knife

(1) New: This status refers to an object that has been generated on the personal digital assistant 101 but does not exist in the server 1〇7. The "addition, object operation, or "method" appropriate for the corresponding item must be transmitted to the server during the next synchronization. Some attributes of the new object, such as the unique object, need not be generated by the server 107 and passed back to the personal digital assistant, and it is determined that the server 1〇7 operation is successful. Of course, if the increased operation is unsuccessful, the server Zhejiang needs to transmit this ^ ^ to the personal digital assistant 1〇1, so that the personal digital assistant 1〇1 can take the appropriate ^ (2) ~ update · · an object The update has been updated in the local Personal Digital Assistant 101 tribute storage area since the last synchronization. At the same time of the update, the updated value of the object must be transmitted by 16 ΓΙ 250139 for 1] 3⁄43⁄43⁄4. Any conflict that can occur in salty, such as two inter-picture sales, conflicts in one product, will be solved on server 1 (37) (then four pictures). Then the updated items are re-transmitted to personal digital assistant ι副本ι The copy of the personal digital assistant and the consistent digital assistant on the server 107) The updated object must also briefly describe the conflict fact: knowing that the individual (1)H cannot be stored: is designated as "cannot be stored, The object comes from the feeding machine and is saved to ^ digit = 101. If necessary, the object can be counted by the individual ^ 3 2, for example, the personal digital assistant temporarily needs a data item, and the attribute is from time to time, the individual The digital assistant 1〇1 can change the state of the object from "cannot store, store the meaning of the = transitioner, so that its attribute value is preserved in a homomorphic pre-疋() stale. is designated as "stale," The object is kept in the personal digital assistant 1〇1, which is included in the synchronization process. The personal digital assistant ΐ() can be sold according to j = self-mosquito mosquito or "clear the old object of the specified domain (4) _ material storage 2 shift The object of #^=定除" means the one that has been from the personal assistant rib. The guest/can delete the information from the 1st step, which needs to be transmitted to the server and removed from the local data storage area. The specified state of the mental object of the gamma is not available when the service is successfully deleted. Simply make a silk towel ===3 joint = in the library, the generation of the preservation of the shape of the 皞 f f 汨 attribute value of the dry circumference. Another _ kind of alternative. For example, a 'can not save cattle = same, state isolation In the different (four) can be guaranteed to be converted into "save, peak (four) preservation, only when the "no step 509 is to step 5U or πσ, 101 is in the online state, is in the turn of the results of the individual oil-reducing number of assistants < φ then turn (four) 513 _ _ _ _ = 服 1 状 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 And then return to the step, in which the personal digital assistant - straight to standby until it establishes a connection between the feeder and the feeder 7 - periodically check whether a connection is established, such as # The connection period is a periodic scheduling event or data transmission by the server 107 Initialization, etc.; or when the personal digital assistant ribs to convey - or more than one Wei is set to initialize - a link already has. If the personal digital assistant 1G1 is waiting for the fine = pick # two of the subtraction, scale Will be the same as the pre-ship transaction, the shop will be linked to the money of the Langbu team, and the performance can be generated - the step of deleting the steps. The synchronization period mentioned above can be fixed or variable. The private can be established by the personal digital assistant 101 or the user interface (υι) on the server 107.

The user can also initiate a synchronization process by the personal digital assistant 101 or the server 107 via the user interface. If at the same time as the initialization-synchronization process, the personal digital assistant 101 and the player 107 in the initial synchronization process are placed in the synchronization sequence in the personal digits of the 〇ι〇ι and the feeding device, and the Ht connection request is placed in the synchronization sequence. Between the two, whether the necessary conditions for establishing or establishing a connection exist. Once the connection between the two is established, the synchronization process will continue and control process 509 will proceed to step 513. The name synchronization privately needs to keep the local copy of the data consistent with the corresponding on the server 1〇7. I send, based on the data filter, these will be described later in conjunction with the ninth to twelfth figures. A copy of the data object on the personal digital assistant 101, such as local or client resources ' ί through a series of client / feeding server transactions, and the corresponding data object on the server 1 ' 7 'such as servo H-end data Achieve synchronization.

The sending of a synchronization request to the server 107 by the personal digital assistant 101 compresses all of the personal digital assistants 101 that need to be provided to the server in order to perform a specific synchronization action, including a time stamp, a selectable In - select list, or - object that needs to be synchronized "vector," or - synchronization object, and a number of people secret 1 (31 geographical location: optional information of the #讯.

The result label is set with the following items: 1 cattle 1 = sign means that the feeding machine must return the operation related to the operation. Taste touch should return with the updated copy with the number of individuals and their status values. Also, when the feeding device is on the machine, /3) tag (5)): the "Lai 3',, === return related to the operation The type of message that all objects of the furnace server 107 should operate. Φ iron () and its sad value. In addition, a return based on the value of the 107 flag indicates that the personal digital assistant should handle the entire request, and the health officer can limit the returned data range or "synchronize the result object". Based on the location in the location object ^= fruit, ^' then return the data range can also be the user, in the personal digital assistant ^ the city personal digital assistant 1〇1 information, when the user travels to another - city it two storage The district-related restaurant-related information can be based on a public system, such as a global positioning system, which is placed in a hospital, and only through the transmission device, a doctor can include future location information. For example, in the case of the patient's information, the individual can not only download the information of the patient in the room of Wengjianwei (10) to his personal digital number; but the time-to-time label is included in the recording of the surrounding part of the room. Object ω...base object, object sorrow ", - old value object and - optional message field. In - specific behavior = not 19 1260139 All of these synchronization objects must be specified. For example 'in one add and delete sang To make an order, you only need to specify the object to be deleted, and you need to specify it. If you want to specify the item, the time value of the item is only updated or verified. If the synchronization is two, two When a specific object is placed on the device 1〇7, the server 107 will be attached to a certain synchronous object without a piece of the basic object at the time of synchronizing the object. When the step is sent to the personal digital assistant, it will transfer the synchronization result object. The synchronization result time table

Synchronize each synchronized object in the result object: 时间 the time of execution on gamma L107. When the paste step is β, the status field of the step object indicates that the object is in the deputy; the copy of the f table f feeder 107 and the personal digital assistant 101 are new i = like a bad sense - the customer is in the servo Has been updated before receiving the sync request

Suit

(3) Failure: The failure status indicates that the server 1〇7 cannot perform a certain synchronization object. In this case, the message field contains a textual message about the failure status. The raft has no ^ identical · the same state indicates the corresponding object synchronization time stamp of the server, (5) new match: the new match status indicates that since the last time the personal digital assistant 101 requested the time, the corresponding synchronization object The described object is new to the server 107. - inch 疋 衣 (6) mismatch: the mismatched state means that the server 107 can not find the corresponding value object, probably because it has been deleted or changed, so that it no longer matches the synchronization request object to provide ^ information over 20 1260139 filter. The = status field and its corresponding feeding operation will depend on the sixth_detailed description. In the case of 2 ί and 2 = 3, the process 500 will continue to the good state return step 5 Π, = the analysis = the return message of the server 1 〇 7 to verify that the object in the synchronization step 513 is the second wedge J 51 =, sorrow The value of Gongxun indicates that a certain data update creation operation is successful, and the J^ system block 517 turns to the flag data state step 5〇9, in which step 107 417 /, inch, spoon, back 5 holes indicate an update or The creation operation is the same in the server 107 JL, the force; 517 521 , , ti; and the storage area 417 of the presence server 107. In addition, any further step-by-step operation is required on the digital assistant 101 based on the updating or operation of the data item. Is there any interception?

The program 5 - is completed, and the process 500 proceeds to the end step 523, in which the 仃, , , and the mouth are bundled. It should be noted that steps 5Π, 519 and 521 are essentially repeated. If a synchronization_ includes multiple objects and these objects are all formed into a coherent queue, the return information corresponding to each object must be 521. The final end step 523 can be reached.诹M7 519 Sweater 2 corresponds to the typical synchronization procedure _ flow chart of synchronization step 513 (fifth figure). ^Step 6G1 ' When the synchronization request operation is initialized as described in the fifth figure, "Hui step is initialized. Each of the following steps represents an operation that is transmitted from the synchronization request. The program_ is performed from step 6〇1 to the associated delete operation. The acquisition deletion operation retrieves all the objects that have been deleted from the server 1〇7 since the last-time acquisition deletion operation was executed.

Corresponding to the synchronization request object, the acquisition delete operation sends a time stamp and - an optional =, 1D^ table to the server 107. Generally speaking, there is no corresponding i ffj corresponding to the acquisition deletion operation. However, if a particular server 107 performs a two-step process, delete and pin two: hidden - a lean filter can be sent. The time stamp for the delete operation should be set to the time when the personal digital assistant 101 last sent the delete operation (if a certain final message has been sent). If the list of optional IDs is rounded up to the server 107' along with the get delete operation, then the generalizer 107 passes the sync result object back to the personal digital assistant 1 as described above in the fifth description.

Each synchronization result object will contain a vector of the executed components = the time of the two-character execution time and the synchronization object vector Each sync has two 1s and describes the way it exists in the result message with the following four states. If the sync object is broken as "the same, then the object's target is already included in the request message. 25 1260139 Inside. In other words, the personal digital assistant 101 already knows the filter that the object matches. Moreover, the object has not been updated since the time the time stamp in the synchronization request object was displayed. Therefore, the personal digital assistant 101 does not need to make any changes to the local data storage. Server 1〇7 may choose not to send the object to personal digital assistant 101 to reduce the amount of traffic on the network. If the ID of the object is not included in the result message, the number of assistants can still assume that the object matches the filter. Subsequently, the personal digital assistant 1G1 updates the time on the local copy to the time stamp provided in the synchronized result object. After the time stamp is updated, the state of the local copy should be preserved regardless of its previous state. The missing ones remain in the list of IDs that match the filter. ^The result of the synchronization object is marked as "new match,", then the 1D of the known two or two components listed in the synchronization request object is synchronized. That is, the object and the previous-time synchronization operation are performed. In the j-shape, the entire object is passed back to the personal digital assistant 101. The personal digital assistant 101 will update the time stamp to the time stamp provided in the synchronization request object. Person Shop 101 (4) Data Storage Area The status of the object is set to "Save," and the object (1) is also added to the ID local list that matches the filter. The second time is the same as the "update" of the object. The corresponding 1D is sent to the second Lr in the synchronization request object. However, the time displayed by the time stamp of the object provided in the synchronization request is updated by ^. The entire object is transmitted to the personal digital assistant 10, the personal digital assistant for the time ^ 2 to the tributary storage area, (5) when the time label is updated to the synchronization request object is referred to as "with the storage of 1 non-personal digital assistant 101 data The local state of the object in the storage area is set to ί, and ί = 1〇 is also left in the list of IDs matching the filter.

After the synchronization filter is completed, after step 613, the synchronization program (4) is the end of the synchronization program. The synchronization procedure of the figure is 〇一丁十615, and thus the whole subject matter of the present invention is not the subject of the present invention. For example, all but this is a flow chart of the program. The program starts with 1^1 service = 5 data management step 703. A more typical example is step 703 and - Synchronous step-up reception.

If the number of individuals searching for the object is in step 705, the data management program 700 determines that the personal contact 1G1 of the resource is transmitted as "Di, which object|=new, but is marked with step 7G9, by The program compares the transmitted data: =P to check the time stamp of the object. If the stored data object is compared to the delivery: the label and the stored stored object will not be updated, the program jumps directly to the transmission. If the status is new, then the notification personal assistant 101 fails the update operation. If, at step, the time stamp on the send-back message poorer object is later than the stored object, the program determines the transmitted π. War, then the program transferred to 27 1260139;: ΐΓ: 2:2: 13 'Replace the stored object with the transferred object. Then, the mf material is updated successfully in the transfer state step. It should be noted that the object can be recovered. 'Because the data sequence 7〇1 transmitted by the personal digital assistant 101 to the server 107 processes only one' and each transmitted data item needs to be processed by a map before the completion of a synchronous operation.

Although it is not important to use the user interface for this x III port, the following figures use the stylus 207 and the display 201. The gentleman's ear transition page 1001 has several areas that enable the user. Specify the data filter. For example, in the name field 1005, the data filter name "all products are input, and after that, if the "all products," the e-commerce application 310 searches for the information on the filter, such as the product π If the carefree does not exist, the e-commerce application 310 will create a new owner. A sync area 1007 allows the user to select whether or not to include the corresponding data filter in a synchronization program. In this example, the entire product data filter does not contain the soil δ V% sequence because the sync area 1〇〇7 is not marked. If the data filter corresponding to a data filter does not change frequently, the data filter may not be included in the synchronization program. However, some data filtering is as simple as the data filter (not shown), so you need to synchronize, because the user or the seller, I want to return to the day to understand the changes in the company's inventory. The last sync area 1009 displays the date "5/25/01" and the time "4:38:40ΡΜ", indicating the date and time of the last synchronization of all product data filters. The search string 1 〇 11 displays an actual corresponding data filter, which is represented by a grammar that can be recognized by those skilled in the art. In this example, the 'data filter specifies all product data filters to search all the records in the product database, that is, use "PrName" to indicate an attribute in the product database, and use " =, to indicate that the search and display is equal to *. Record. Since * is a general symbol, the data filter will display all the records in the product database. You can use the Backus Naur Form (BNF) symbol to indicate the data filter or query string, the symbols are as follows. = "("filtercomp"),, filtercomp-and | 〇r | simpleFilter and = filterlist or = "| ''filterlist filterlist = l*filter simpleFilter = attributeName filtertype value filtertype = "=,,| ">=,, "<=r,,|" "Bu,, f f-name is ί, corresponding to a column in the product database or file. Binary is not used in data filtering, ie, a data Filters cannot be translated into two JpEG images. For a property, a value can match any allowed login, such as the price of a basketball can be any value, a production The name of the product can be a noun, such as "baseball,,. The eleventh figure is a schematic diagram of the search product page 11〇1 of the mobile e-commerce application 31〇 displayed on the display screen 203 (second drawing) of the personal digital 101 (first and second figures). The page, 1101, 2 login page, by which the page user or salesperson can define or modify the data filter with the display 2 〇 3 and the stylus 207. Similar to the home page 9〇1 (the ninth figure) and the edited page page (similar to the tenth®2), the page 1101 also includes a title block 1103, which contains the page name "Check 5 and the sj day guard" 11:38a"; a state block 13; three state icons ni5, 1117, and 1119. All of the XI have similar functions to the title bar, state bar, and status icons of the ninth and tenth figures. Below, the page has an execution icon and an advanced filter icon 1121. When the user clicks on the icon to execute the icon, one corresponds to the filter displayed on the display screen 31 1260139 t. The filter is created in the present shot. The above = map household = the same, that is, "PrName = *,,. # user with the stylus 2 〇 7 point select the advanced icon 2 2 _ shows the screen will be replaced by another search product display screen, Explain in the twelfth figure of the competition, the fan's display screen coffee allows users to create and change more noisy and advanced data filters.

When the stylus 207 is used to select the search range 1125 edge inverted triangle fl-day display-down-down list, the user can select a sub-material from the product document or the database table, and the user enters a value - the value can be used for It will be defined or created. In this case, the value is "*,,, limb_wildcard, and all records in the text with any value in the slot will be returned. Another example is to lose the batch "11' in the search value area. The beaker will contain all the records in the product slot, including “basebali, baseballs, or “baseball bats”. The two operators can use the search range II25 and search. In the case of this example, in the two symbols, you can only select one of them, that is, =, or, Bu, ., =, the operator Cong means that the user wants I to filter $ return All the attributes of the product smear are entered in the search range 1125, and the value of the input value of the technical value area II27 is matched with the value of g(10). If the user selects "=, then the user wants data filtering, II returns the product wealth. The attribute is the entry of the search range 1125, and the value entered in the value area 1127 does not match. ’,

- Displaying the pair of keys 1109 can specify the blur, face, in other words, the query of the search condition of the person entered in the search range 1125 is not exactly matched as the search value is ιΐ27. The lean filter returns all the information in the product documentation that is close to it.
