Taking customer domain for example, an ontology-based customer metadata model is build and formalized in description logics. Then two kinds of modes for customer information sharing are studied. The two modes are to construct a global c ustomer m etadata m odel w ithin a n e nterprise a nd t o c onstruct a mapping mechanism between customer metadata models located on different enterprises respectively. In the first mode, an information source is regarded as a 3-tuples, including a metadata model, a concept relation set and a resource data set.

然后从两个层面来探讨客户信息的共享机制：一是在企业内部创建统一的客户元数据模型，将信息源抽象成一个包含元数据模型、概念关系集、资源数据集的三元组，对概念关系的构成及获取方法进行分析，随后建立数据请求的模型，并相应地提出基于概念关系和基于术语相似度的两种答复模式。

More than one way of ciphering was available to ensure the network safety.After all,the system had comprehensive laboratory modules,powerful connection capacity with other systems,convenient ways to input,standardized coded tests,all??round and authority reference values data??base,and,original dynamic management assistant function.

It becomes a information exchange site,the exploration project,work area,research production,seismic datum,explainer datum,well datum can be organized into one system,which can share the research production in the exploration project;Through the datum expression of well decision,we can achieve the browsing of work area basemap,the seismic section"s remote display,the well position report"s display,the visual information of well"s wall.The system can lead to a right direction for those expert"s exploration decision .The system runs through all the process of well positon"s decision,deployment and management,which makes the exploration work becoming integrated.Now we can manage the well positon"s decision with computer,which improves work efficiency,condense whole exploration circle.

油田井位部署辅助决策系统以项目数据库的方式将分散在多个研究单位或个人手中的各类图档资料信息集中分类地保存起来，通过该系统使勘探项目、工区、研究成果、地震数据体、解释数据、井数据等有机地组织在一起，使勘探研究成果在勘探项目组内进行了充分共享；基于项目库，系统实现了井位部署决策所需的：工区底图浏览、地震剖面远程显示、井筒信息可视化，为论证专家提供了论证现场所需数据的展示；采用井位聚类分析和模糊数学综合评判决策方法，为井位论证决策提供了基本模型；利用井位部署流程子系统贯穿了井位论证、部署、管理业务的全过程中，使勘探业务有机的整合为一体，实现了井位论证工作的计算机管理。

The innovation and the breakthrough point of the system research chiefly shows in: finding out the effective forecasting technique of formation, oil and gas water bed and formation pressure , internal/external sharing of data, automatic examination of related data, automatic drawing of three kinds of graph, automatic showing the well position on the structure well position map according to the designed coordinate of well,pretreatment technology of design, generating of design book, mixed arrangement of graph and text, transmission and examination of design book on net, computer management of design book and data, on net query, data compressing technology, etc.

系统研究的创新和突破点主要表现在：总结出一套行之有效的钻遇地层、油气水位置预测方法和根据邻井综合录井资料预测地层压力方法，开发了系统数据内外部共享和相关数据的自动校验、三种图件的自动绘制和在构造井位图上根据设计井座标自动展井位、设计预处理、设计书的生成和图文混排、设计书网上传输和网上审批、设计书和数据的计算机管理和网上查询、大数据压缩等技术。

Several problems are resolved in the system, such as the data access in the memory, parallel file access from disk, and the replacement of file data.

解决了并行文件访问的难点：内存中数据的读写，并行化磁盘读写和文件数据的替换，性能测试表明在多用户并行处理的环境中，Parfsnow++有效地提高了系统性能，特别是在文件数据的共享，文件数据的替换，以及使用大容量的统一内存对文件数据的存取等方面。

Facing distributive network share and application service, it divides government affairs information data into the follows: relational data, geographical spatial data, document and media data and so on. By carrying out the reform of multi-source and different-structure information resource, whose main contents are standardization, formulation and spatialization and the complete register of metadata.

面向分布式网络共享与应用服务，将政务信息数据分为关系型数据、地理空间数据、文档和媒体数据等类型，开展以标准化、规范化和空间化为主要改造内容的多源、异构信息源的改造，并进行完整的元数据登记造册。

Moreover, it contains advanced surfacing, extensive data translators for sharing and reusing engineering data, mechanism design for moving assemblies, shrinkwrap and simplified

而且，它还包含了高级曲面，用来共享和重复使用的工程数据的广泛的数据转换器，用来移动组件的机构设计，收缩范围和，协助数据重复使用的模型检查，输入数据的输入数据专家和创建动画的设计动画。

The data location includes memory data memorizer and memory map register, which share uniform data and address buses, at the same time occupy independent physical spaces, respectively, both physical and logic addresses separated and independently addressed, respectively, and can multiplex the same logic address.

内存数据存储器和内存映射寄存器共享统一的数据总线和数据地址总线。同时，内存数据存储器和内存映射寄存器各自占有独立的物理空间，物理地址和逻辑地址均分开，各自独立编址，内存数据存储器和内存映射寄存器对同一逻辑地址可以复用。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
