Description
Technical field
The present invention relates to the GIS data process field, particularly the service aggregating method of the service aggregating method of a kind of service aggregating method of client and device, a kind of Web server and device, a kind of GIS server and device, a kind of GIS service aggregating method and a kind of GIS service aggregating system.
Background technology
(Geographic Information System is the computer system that is used to gather, store, manage, handle, retrieve, analyze and express geographic information data GIS) to GIS-Geographic Information System, is the current techique of analyzing and handle the magnanimity geodata.
Entered since 21 century, GIS obtains fast development in the application of all trades and professions, and the GIS platform software develops into the crucial platform class software of IT field from the software engineering of a specialty, is bringing into play important effect in growing field.At present, the GIS application system has been widely used in providing the service management service for enterprise.
Traditional GIS service plan is, integrated with GIS and operation system by direct access service data of database in generalized information system, carries out data processing and analysis then in this generalized information system, and output and present the result.The coupling of generalized information system and operation system is strong.Business scenario with the realization vehicle tracking is an example, adopt traditional GIS service plan, at first use GPS (Global Positioning System, global positioning system) gathers and follows the tracks of the information of each vehicle, then with these data information memory in Service Database, last generalized information system is analyzed by the information that reads in the Service Database, and the result is represented client.
Yet this traditional GIS service plan can be brought following problem:
1) generalized information system needs direct access service database, must open the corresponding database authority, and data can not be isolated fully like this, have potential safety hazard;
2) applied logic of generalized information system and operation system is integrated realization in same system, can be implicative of each other when taking place to change, and is unfavorable for the expansion of system reuse and function;
3) function of generalized information system is just used to the current business system, rather than uses for different operation systems jointly as independently serving;
4) function of generalized information system and service are not only upright, are difficult to the formation standard, and service logic needs secondary development to realize usually, rather than standardized, configurable mode realizes the process complexity.
Based on the problems referred to above, be faced with a predicament in the current GIS application development process, that is exactly the quick variation that system is difficult to the demand of getting caught up in.For the SFC support, after system development was finished, in case adjustment has taken place for business itself or operation flow, maintenance will constantly be revised by system, and workload is very huge.For application units, if maintenance does not catch up with, the system that drops into a large amount of human and material resources and financial resources just builds up, and becomes very soon in face of demand and has fallen behind.For the developer, finish the system of a unit, if will be generalized to other unit of the same trade, although can find that professional difference is little, because those tiny demand difference, system originally is difficult to directly promote, still need system is much revised, workload is still bigger.In the application of GIS, these problems can be summed up as professional quick (Business Agility) problem.
So-called professional agility comprises two layers of meaning: the first, and IT responds this variation in an appropriate time period after business proposes to change; The second, the variation that IT made can reflect professional demand rightly.
In the prior art, proposed to depend on SOA (Service Oriented Architecture, service-oriented architectural framework) and realized professional quick design, SOA is not a kind of concrete technology, but a kind of framework thought.SOA emphasizes loose coupling and crude density, and in the application program of SOA, the developer only need pay close attention to writing of service logic, and exposes service logic by service destination node (ServiceEndpoint) tradable, interoperable.These destination nodes of client call, rather than service code or its realization bag.Therefore SOA has more high efficiency code reuse mechanism, can make up application system by dynamic on-demand, more helps to realize professional quick.
Yet in existing GIS field, SOA typically uses the mode of WebService, mainly towards interface interchange, and in the GIS field, there is specific service regulation, as OGC standard etc., the mode of WebService is not necessarily used in service, and often needs client end interface and present map;
Moreover, because the WebGIS platform is mainly issued towards information, the GIS function is simple relatively, can't replace assembly type GIS to realize the repertoire of application system, to such an extent as in actual applications, have to mix and use polytype GIS software to come the Application and Development system, as WebGIS and assembly type GIS etc., the pattern that the framework of application system also often adopts B/S and C/S to mix;
In addition, because the WebGIS server end does not possess service aggregating (ServiceAggregation) ability, the simple aggregation of being undertaken by secondary development person in the WEB client, be difficult to satisfy whole demands that large-scale professional application system builds, be difficult to also realize that the service after the polymerization issues in the mode of standard once more so that by third party's polymerization;
And, client GIS software (desktop GIS and assembly type GIS) also lacks complete service aggregating ability, even having, idol supports to use Web data or Web service, also often there are many restrictions, external service is taken as the second-class citizen, can't use very easily, also be difficult for being complementary with existing conceptual model.To such an extent as to the pattern of above-mentioned B/S of using with and C/S structure is difficult to form incorporate system by service assembly.
Thereby the WebGIS of this support of prior art SOA still can not satisfy professional quick requirement.
So, need the urgent technical problem that solves of those skilled in the art to be exactly at present: the mechanism of a kind of GIS service aggregating of proposition how can innovate, in order in the GIS field, service dissimilar, separate sources is carried out integrated integration by the standardization flow process, and be distributed to the GIS client by uniform way, better SOA is combined togather with GIS, satisfy the GIS field to professional quick demand.
