Adopt ASP. NET 2003 is regarded as the developing instrument, the design of storehouse of the data follows 3 normal form :, have designed the coding schedule of goods and materials mainly, tombarthite product structure catalogue, basic information slip of the job centre, route form of the craft , project code of the expenses, journal ledger of the cost of goods, subsidiary ledger of the cost of goods, department's form, measurement unit form, the supplies inventory safeguards the counting type structure form, real expenses form, share the proportion form in power of kinetic energy, salary expenses share proportion form, amortization charge share proportion , maintain expenses share proportion , test expenses share proportion , main frame left menu tree form , material price list ,etc. data list

采用ASP 。NET 2003作为开发工具，数据库设计遵循第三范式，符合第二范式的条件，每个非关键字属性都仅由关键字决定，而且一个非关键字属性不能仅仅是对另一个非关键字属性的进一步描述(即一个非关键字属性值不依赖于另一个非关键字属性值)。，主要设计了物资编码表、稀土产品结构目录表、工作中心的基本情况表、工艺路线表、费用项目编码、产品成本总帐、产品成本明细帐、部门表、计量单位表、物料清单维护数型结构表、实际费用表、动能功率分摊比例表、工资费用分摊比例表、折旧费用分摊比例、维护费用分摊比例、化验费用分摊比例、主框架左菜单树表、材料价格表等数据表。

SQL Server database used by the query language called Transact-SQL, SQL Server is the core, Transact-SQL strengthen the original SQL keywords for data access, storage and handling, and other functions, Transact-SQL expanded Process control designation, so that you can facilitate the preparation of the powerful storage process, they kept in the server side, pre-compiled and that the implementation rate is very block, the trigger is a special storage process, SQL Server database to ensure the integrity of quote , You can create insert, delete and update the trigger to control the relevant data in the table shown in the insert, delete, and update, you can also use the rules, default and restrictions, to assist the new Numerical applied to the table!

SQL Server所使用的数据库查询语言称为Transact-SQL，它是SQL Server的核心，Transact-SQL强化了原有的SQL关键字以进行数据的存取，储存及处理等功能，Transact-SQL扩充了流程控制指定，可以使你方便的编写功能强大的存储过程，他们存放在服务器端，并预先编译过，执行速度非常块，触发是一种特殊的存储过程，用来确保SQL Server数据库引用的完整性，你可以建立插入，删除和更新触发以控制相关的表格中对数据列的插入，删除和更新，你还可以使用规则，缺省以及限制，来协助将新的数值套用到表格中去！

Those by accident the alleged education of person future, advertise an user to submit the Sitemap, key word that adds magnanimity for the site often; is operated this kind in fact not only refer profitlessly, likely instead because of data too too frequent, bring about search index to prop up for resource conservation set database to answer the Ping that comes from your domain name to request no longer, the keyword is too much go against index analysis, load slow and by oversight .

那些误人前程的所谓教学，鼓吹用户频繁提交Sitemap、为站点加入海量的关键字；事实上这类操作不但无益、反而有可能因为数据提交太过频繁，导致搜索引擎为了节约资源而设定数据库不再响应来自你域名的ping请求，关键词太多不利于索引分析、载入缓慢而被忽略。

The program produces HTML based reports that can be output to a folder of your choice and include graphical, as well as text based statistics with sortable columns from a multi-page interface.

该数据库允许你创建独特的关于你的访问者登陆以及被使用的关键字和短语的搜索引擎的报告展示统计表。Alterwind从搜索请求中收集一些额外的信息，诸如在页面上访问生成的搜索结果的数量。你可以按国家或者语言排序该信息。

XML keyword search is easy to use, and users do not have to understand the schema, recently is widespreadly concerned by the people.

XML的关键字检索简单易用，用户不必了解数据库的模式，受到人们的广泛关注。

Because DHT methods just provide exact-match query facility, not satisfying the flexible query requirements, the paper also discusses a scalable, flexible multi-keyword resource located technology. The paper proposes the filtering conjunctive operation scheme similar with distributed database. It also includes an incremental search over the peers to decrease the query latency and bandwidth consumed. Lastly we investigate the popularity of user search behaviors and provide the cache strategy to reduce the overhead associated with operations spread across the wide area to provide the efficient resource query and access in scalable P2P system.

由于分布式哈希路由算法只能提供精确的资源定位，不能满足人们灵活的查找需求，因此本论文也讨论了一种便于扩展，灵活的多关键字资源搜索与信息服务技术，提出类似分布式数据库的过滤器连接算法，并采用增量式查找算法减少查询延迟及带宽消耗，利用缓存策略加速查询，以期为大规模的P2P网络提供高性能的资源搜索与数据访问服务。
