Based on business events and their relationships, four service mediation primitives were presented to realize loosely-coupled interoperations and data exchanges among services 基于業(yè)務(wù)事件關(guān)系,給出了四個(gè)服務(wù)中介操作原語,以實(shí)現(xiàn)網(wǎng)格環(huán)境下服務(wù)之間更為松耦合的交互和數(shù)據(jù)交換。
To facilitate the interoperations among autonomous, dynamic and semantically inconsistent services in grid environments, an event-driven service mediation mechanism was proposed to deal with dynamic service matching and interoperation 摘要為實(shí)現(xiàn)網(wǎng)格中自治、動(dòng)態(tài)和語義不一致的服務(wù)之間的互操作,提出一種事件驅(qū)動(dòng)的服務(wù)動(dòng)態(tài)中介機(jī)制,以解決網(wǎng)格中服務(wù)的動(dòng)態(tài)匹配和互操作問題。
But the increases of application systems are also causing that data interoperations between them was more and more than before, the relationships between them more complex, and these systems being deployed in non homogeneous distributed computing environment . all these aspects are causing the maintenance costs of application systems too much high, the enterprises slowly meeting requirements of customers, and the couplings between systems too much strong 但是,隨著應(yīng)用系統(tǒng)的增加,各個(gè)應(yīng)用系統(tǒng)之間需要的數(shù)據(jù)互操作愈來愈多,系統(tǒng)之間的關(guān)系愈來愈復(fù)雜,而且企業(yè)計(jì)算環(huán)境通常是異構(gòu)分布式計(jì)算環(huán)境,這造成了整個(gè)企業(yè)的管理信息系統(tǒng)的維護(hù)成本增加、應(yīng)對復(fù)雜多變的應(yīng)用需求滯后、各個(gè)應(yīng)用系統(tǒng)之間的耦合性強(qiáng)、魯棒性差等缺點(diǎn)。
Architectures and key technologies of three popular distributed object computing models, i . e . corba, dcom, ejb / rmi, are deeply discussed . their interoperatio ~ s and implementation technologies are then studied, including the interoperations both for a single model and among several mmels 本文在深入探討corba、dcom、ejbrmi三種流行的分布式對象計(jì)算模型的體系結(jié)構(gòu)及其采用的關(guān)鍵技術(shù)的基礎(chǔ)上,進(jìn)一步研究了分布式對象計(jì)算模型的互操作性及實(shí)現(xiàn)的技術(shù),包括單一模型內(nèi)的互操作性問題和異種模型間的互操作性問題。
Many domestic and international organizations have set up standards of geographical information . the open gis consortium is international standardization organization with influence . the open geo-data interoperability specification intends implementation share and interoperations of geo-data by open geographical information system with industry standards and open interfaces 在國內(nèi)外有許多組織已經(jīng)制定了各種地理信息系統(tǒng)標(biāo)準(zhǔn),opengisconsortium是一個(gè)國際性的、具有一定影響力的標(biāo)準(zhǔn)化組織,它提出了開放的地學(xué)數(shù)據(jù)互操作規(guī)范,通過行業(yè)標(biāo)準(zhǔn)和接口建立開放的地理信息系統(tǒng),實(shí)現(xiàn)地理信息互操作和共享。
