Abstract
A client/server system for exclusive control, that is, providing efficient edit job to each client is composed of one server and several clients. Said server has a memory unit containing the main data file as edited object and the locked image list of all the registered edited objects for the clients, and an operation unit which has an edit record analysis unit for analyzing the edit record files written to clients.
Description
The present invention relates to the client server system that several client computer are edited the data of server admin, the particularly exclusive control of the editing data between several client computer and (unification) technology synchronously.
For example, be set at the situation that several client computer are edited the map datum of server admin (for example client computer A describes road A, and client computer B describes road B etc.) separately.About the editing and processing that several client computer are carried out simultaneously, server must guarantee its compatibility and unitarity.For example, Fig. 1 is provided the map datum of (A) simultaneously for client computer P and client computer Q by server, client computer P carries out the editing and processing of the road 100 shown in this figure (B), client computer Q carries out the editing and processing of the road 200 shown in this figure (C), in this occasion, in order to reflect the order of each client computer P, Q, server is such shown in this figure (D), confirm net result, and must inform each client computer P, Q (promptly unifying synchronously of editing data) to this net result.In addition, must guarantee that also the edited result that edited result that client computer P carries out and client computer Q carry out is complementary (compatibility of editing data), that is to say, not contradict (for example client computer P, Q can not carry out multi-form editor equally about same road).
Therefore, common server is divided into several data sets to total data and manages, and for a data set, only distributes the exclusive control of a client computer.That is to say that server carries out the data interlock that client computer Q can not edit for the data set of the edit object of client computer P, after the client computer Q editing and processing, remove this locking, become the edit object of client computer Q.
Size as the data set of 1 unit of above-mentioned exclusive control is set at the significant problem which kind of degree is left and right sides editorial efficiency or easy-to-use degree.For example,, in advance whole map image is carried out netted cutting apart at interval according to certain longitude, latitude in the occasion of using as map edit, can be 1 unit of such as the data set of the whole figures that exist in one of them grid, literal etc. as exclusive control.But, in this occasion, for example, when certain client computer began to edit to the figure by long several grids apart from railway track, before finishing to this editor, other client computer can not contact other several grids, in fact, brought inoperable problem.In order to address this is that, the unit that also can make exclusive control is the various figures (promptly be unsuitable for cut apart, edit minimum data) of different kinds of roads on the map or buildings etc.But,, just must from map datum, retrieve other graph datas as data base administration in case the unit of this exclusive control diminishes.And if database is when becoming huge database, this retrieval just needs the expensive time, has brought the problem of operating efficiency deterioration.
In addition, in client server system in the past, for the editing and processing one by one of each enforcement, client computer is all sent the notice of the content that will implement editing and processing to server.Server judges that whether the editing and processing of being notified permits, if be judged as permission, according to its content update database, afterwards, feeds back to client computer to this renewal result.Receive the client computer of upgrading the result, this result of reflection in the application of oneself.In addition, server also sends above-mentioned update notification to each client computer beyond the client computer of notifying above-mentioned edited result.Each client computer of receiving update notification also reflects this result in the application of oneself.So, client computer only collect and server between various notices, and substantial editing and processing is carried out under server is leading entirely.
Therefore, in case the client computer change is many, require the treatment capacity of server to expand, it is very big that load of server will become.In addition, before reflecting the editing and processing result in the application of each client computer, will come and go various requirement or notice between client computer and the server, therefore processing is time-consuming in the extreme, and before edited result is reflected in other client computer, also will spend a lot of time.
Therefore the purpose of this invention is to provide the client server system that a kind of each client's function is carried out editing operating expeditiously.
Another object of the present invention provides a kind of client server system that can inform the operation result of each client computer at high speed other client computer.
According to first aspect present invention, a kind of client server system is provided, server comprises: the locking tabulation of login blocked Target Recognition symbol for any client computer is edited; Reach the notice portion that this whether locked information of the desired editor's of each client computer target is notified to each client computer with reference to this locking tabulation.Therefore, accept the client computer of notice, do not have the target of locking to be in editing mode but can make.
According to a second aspect of the invention, provide a kind of client server system, at first, server is given client computer object transmission; Client computer is freely carried out editing and processing to the target of accepting from server, after this editing and processing, generates the difference record that editor's target changed content has been carried out in expression, and sends server to.Then, server reflects the content of the described difference record that is transmitted in self-administered data.Therefore, the data between server and the client computer are data in synchronization.
In most preferred embodiment, server sends the difference record that is transmitted to the client computer client computer in addition that transmitted this difference record; Then, accept client computer, the content of difference record is informed oneself by the described difference record of server transmission.Therefore, by this client server system integral body, can make data syncization.
Fig. 1 is the figure of the variation of the edit object data on expression is used.
Fig. 2 is the figure that the integral body of the client server system of expression one embodiment of the invention constitutes.
Fig. 3 is the flow diagram of expression editing and processing flow process.
Fig. 4 is that to make entire system be the figure of synchronous treatment scheme to the expression client server system.
The description embodiments of the invention
Fig. 2 is the whole pie graph of the edit mode of expression one embodiment of the invention.
Client server system of the present invention has a service computer 1 (hereinafter to be referred as server) and several subscriber computer 3a, 3b ... (hereinafter to be referred as client computer).Hereinafter, to supposing these client computer 3a, 3b ... the situation of the map datum of editing server 1 management describes.
Server 1 has as the function of server with the map editing application, comprises management department 4, storage part 5 and operational part 7.The relation of each one in management department's 4 management servers 1, and management server 1 and client computer 3a, 3b ... relation.For example, management department 4 applies all orders for each one in the server 1, and delivery server 1 and each client computer 3a, 3b ... between various notices or data (narration hereinafter as required of the function more specifically of management department 4).
The storage part 5 of server 1 has these client computer of storage 3a, 3b ... the master file 9 of editor's map datum (for example, the map datum in the Japan whole nation).Each client computer 3a, 3b retrieve in management department 4 from master file 9 ... the map datum of the region (for example specific scope that latitude, longitude surrounded) that requires, and send each client computer 3a, 3b to ... based on each client computer 3a, 3b ... the editing and processing of being carried out, the more content of new master file 9.
This client server system can be for carrying out exclusive control as the data of the least unit of edit object with the user.The data of so-called least unit are to be unsuitable for the data of separating, edit, for example, in the present embodiment that carries out map edit, can be the graph datas of representing the various geographical aspects such as highway, railway line, buildings (below be called target) on the map; In the application of making file, can be a lteral data or word data or a sentence data; In the application that tabulation is calculated, can be a cell data, line data or column data (in this occasion, lteral data, word data or a sentence data, perhaps cell data, line data or a column data are target).Therefore, for example, in the occasion of carrying out editing and processing of client computer 3a to the building A on the map, other client computer (being the client computer beyond the client computer 3a) are not carried out all editing and processing about building A, but, for the target beyond the building A, so long as the object of editing and processing, other client computer just can freely be carried out editing and processing.
The storage part 5 of server 1 has login as any client computer 3a, 3b ... the target of the figure of the targeted graphical symbol of current editing and processing object locking tabulation login in this graphical list is current locked and other client computer can not be as the target of new edit object.Each whole figure on the map image in the master file 9 indicate the figure sequence number of a meaning, in figure locking tabulation 11, have only blocked targeted graphical sequence number just to be logged, and graph data itself is not logged in this locking tabulation 11.Management department 1 is inquiring from client computer 3a, 3b ... certain target locking could situation under, with reference to figure locking tabulation 11, judge that whether locked certain target of inquiry be, and this judged result sent to client computer 3a, 3b ...In addition, management department 4 is having from client computer 3a, 3b ... the occasion of the notice of appending or deleting order of blocked target, the figure sequence number of the target of being notified is write in the figure locking tabulation 11, and deletes simultaneously.
The operational part 7 of server 1 has reference record analysis unit 13, and 13 pairs of this reference record analysis units have write each client computer 3a, 3b ... the content of the reference record file of the editing and processing difference record of carrying (data of the difference before the expression editor between target and the editor back target) is resolved.Management department 4 accepts by client computer 3a, 3b ... editor's log file, and send reference record analysis unit 13 to.And reference record analysis unit 13 is resolved the content of this reference record file, and management department 4 is based on the data of the content update master file 9 of the reference record file of this parsing.In addition, management department 4 has the function of the client computer (being client computer 3a client computer in addition) that will send to other from the reference record file that certain client computer (for example client computer 3a) is accepted same as before.Being transfused to has each of reference record file client computer to resolve the content of this reference record file, and informs oneself, thus, makes map datum (unification) synchronously by this client server system integral body.
Each client computer 3a, 3b ..., have the function with the map editing application, and comprise storage part 15a, 15b as the user ..., operational part 17a, 17b ..., user interface part 18a, 18b ...
Each client computer 3a, 3b ... accept the map data file of the desired region of server 1, storage part 5 this document as local file 19a, 19b ... store, and store editor's lock file described later simultaneously.
Client computer 3a, 3b ... operational part 17a, 17b ... have the 20a of editorial office, 20b ... with reference record generating unit 21a, 21b ...
The 20a of editorial office, 20b ... according to user's indication, on map image, write road or buildings, while the mode to move, to make its distortion, also to delete simultaneously, to local file 19a, 19b ... data carry out various editing and processing.
Reference record generating unit 21a, 21b ... generation is used to represent the 20a of editorial office, 20b ... the reference record file of the editing and processing difference of being carried out, and temporarily be stored in storage part 15a, 15b ... in, suitably send server 1 to.In addition, reference record generating unit 21a, 21b ... the content of the reference record file that parsing sends from server 1 is reflected to local file 19a, 19b with the content of this parsing ... in.Thus, by this client server system integral body, make map datum (unification) synchronously.
Fig. 3 shows the editing and processing flow process
At first, when the map edit that starts client computer 3a was used, the map edit of this client computer 3a was used (hereinafter to be referred as client computer 3a) and is just signed in in the server 1, then, required the map data file (S1) of the region that the user edits for server 1.Server 1 retrieves the file (S2) of requirement from master file 9, and sends client computer 3a (S3) to.Client computer 3a accepts file from server 1, and the file of this acceptance is preserved as local file 9a, simultaneously, opens this local file 9a (S4).Then, client computer 3a shows the map (S5) of this local file 9a on the map edit picture on the display, be in the state that the user carries out editing operating.
Secondly, the user carries out given operation on the map edit picture, and specifying the desired target on the map is edit object (S6).For example, the user considers to adopt method operation mouses such as click, on the display cursor is being placed on the desired target, specifies the target as edit object.
In case specified the target as edit object, client computer 3 just sends the figure sequence number of intended target to server 1, inquires whether this target can lock or how (S7).The management department 4 of server 1 judges that with reference to figure locking tabulation 11 whether the target of being inquired can lock (S8).Be that management department 4 is with reference to figure locking tabulation 11, if lock in the tabulation 11 at figure from the target of client computer 3a inquiry, other client computer (client computer beyond the client computer 3a) are among the editor of this target, then judge client computer 3a for editing, the figure sequence number of this target and the meaning that can not lock (promptly can not edit) are sent to client computer 3a (S10) as locking information.In addition, if lock in the tabulation 11 at figure from the target of client computer 3a inquiry, other Any user is not among this target of editor yet, then management department 4 judges that client computer 3a is for editing, in figure locking tabulation 11, write the figure sequence number (S9) of this target, simultaneously, the figure sequence number of this target and the meaning that can lock (can edit) are sent to client computer 3a (S10) as locking information.This locking could affirmation action in, because the figure of watch list locking tabulation 11, can judge have only blocked target the figure sequence number for whether to lock, therefore, with comparing according to retrieving the method for confirming as the data that could lock the storehouse in the past, can in the extremely short time, judge and to lock from googol.
Client computer 3a obtains locking information (S11) from server 1, for lockable target, just can carry out the pattern (S12) that can edit.Admissible method has, and for example, the client computer 3a expression target that can lock etc. of overturning on display demonstrates the order that the user can edit.In addition, for the target that can not lock, the expression of need not overturning shows the information of " can not edit " etc., and notifies the user on display.
If specified target is editable, the user just can carry out various editing operatings (S13) to this target.As this editing operating, can consider to carry out the size, shape, color etc. of buildings on the map for example or road change, append, deletion etc.
Then, whether client computer 3a is all over to the editing operating of the target of editing about the user and judges (S14).For example, the occasion of certain buildings on user's edit map, the user specifies other target beyond this buildings, and when perhaps carrying out the operation of map edit application end, client computer 3a judges that this editing operating of this buildings is for being all over.Return in the unclosed occasion of editing operating, return step S13, the user proceeds editing operating.
In the occasion that editing operating finishes,, specify new target if the user the editor who carries out other target, then returns step S6.In addition, parallel therewith, reference record generating unit 21a makes reference record file (S15) to the record of the editing and processing of a target of current end.Being stored in record in this reference record file and being the difference record of the variation point of only representing editing and processing and being produced, is not image recording behind the editor of the target behind the expression editor itself.Then, client computer 3a transmits (S16) to the reference record file that generates to server 1.
The management department 4 of server 1 accepts the reference record file (S17) of transmission, and flows to reference record analysis unit 13.Reference record analysis unit 13 is resolved the content (S18) of reference record file.Management department 4 is according to the content of resolving, and more the content of new master file 9 (promptly, this target update being the state after editing) (S19).Thus, become the state of (unification) synchronously between client computer 3a and the server 1.In addition, management department 4 sends this reference record file also for the client computer beyond the client computer 3a, like this, makes client server system whole (unification) synchronously (S22).About This move, continue step S22, describe with Fig. 4.
On the other hand, client computer 3a determines the releasing (S19) of the target lock-on after editor finishes, and the figure sequence number of this target and the order that unlocks are sent to server 1 (S20) as locking information.The management department 4 of server 1 accepts this locking information, and deletion shows the targeted graphical sequence number of this locking information from figure locking tabulation 11.
Fig. 4 shows the treatment scheme that this client server system that continues the step 22 among Fig. 3 makes all data sync of system.
It (is client computer 3b that there is the client computer 3a client computer in addition of reference record file in 4 pairs of the management departments of server 1 as input ...) the client computer of in server 1, having done login (hereinafter to be referred as the login client computer), inquiry map edit application start is (S31) whether.
Each logins the inquiry (S32) of client computer acceptance from server 1, and the answer to this inquiry is sent to server 1 (S33).Server 1 judges that based on this answer whether respectively login client computer startup map edit uses (S34).Then, management department 4 only transmits the reference record file of accepting from client computer 3a (S35) to the login client computer of answering to YES (promptly starting map edit uses).The reference record generating unit 21 of accepting the login client computer of reference record file is resolved the content of reference record file, and the login client computer is resolved content based on this, upgrades the content of local file 19
In addition, for the login client computer of answering to NO (being not activated map edit uses), the release of management department 4.In this occasion, the login client computer that is not activated the map edit application starts map edit in the back and uses, requires to edit when wishing the map datum of region, as the step S3 of Fig. 3 was illustrated, server 1 was read corresponding map file in master file 9, flow to the login client computer.The content of the file of this conveying is upgraded in the step S21 of Fig. 3, and therefore the content of the file of process renewal informs local file 19 in the step S4 of Fig. 3.
In addition, same with above-mentioned explanation even for the client computer of not logining in server 1 in step S31, when the startup map edit of back was used, the content of the file that upgrades in master file 9 also can inform local file 9.
By above action, this client server system by system all after, map datum becomes the data of (unification) synchronously.
More than, most preferred embodiment of the present invention has been described.But the foregoing description is only used for the example that the present invention will be described, and scope of the present invention has more than qualification in this embodiment.Those skilled in the art under the prerequisite that does not break away from aim of the present invention, in the various examples of other outside the foregoing description, makes various distortion, improvement, modification, simplification etc., still can implement the present invention.For example, the formation of service user system is not limited to the client server system of above-mentioned centralized services type, also can adopt the distribution services type client server system that is provided with several servers.
In addition, this client server system also can be used for the application of for example article making or the medium various application scenarios of application that tabulation is calculated except the application of map edit.And, be not limited to figure as edit object, also can be literal, mark, image, music etc.
Further, aspect the unit of exclusive control, can consider panoramic variation.For example, each group that a unit of exclusive control can be an edit object of the same race for example, in map edit is used, admissible method has: can make with the road data group that comprises the whole road datas on the map and be unit of exclusive control and be the group of every kind of implication of target on the expression map of a unit etc. with the buildings data set that comprises whole buildings data that these groups are as a unit of exclusive control.In addition, be under the situation of edit object at literal etc., a unit of exclusive control can be each literal, each sentence, each paragraph or each chapters and sections etc.
