制造业信息化的基础平台将是internet intranet ， xml ( extensiblemarkuplanguage ，可扩展标记语言)已经成为internet intranet环境下数据表达的事实标准，而目前企业大量数据仍存在于占主导地位的关系数据库( relationaldatabase ，简称rdb )中，如何在rdb与xml之间架起数据交换与数据操作的桥梁，已成为制造业在internet intranet环境实现信息化迫切需要解决的突出问题之一。 | | 4. | Aiming at this problem , the main research issues and achievements in this paper are as follows : bi - directional data transformation between rdb and xml with semantic constraints preserved for most of existing researches on static data transformation between xml and rdb , dtd is taken as the schema description language for xml , and the semantic constraints are often lost during the transformation process . to overcome these disadvantages , the author adopts xml - schema , a standard schema description language proposed by w3c to replace dtd , as the description method owing to its more powerful functions than dtd , and of course with the syntax much more complicated . after analyzing the constraints characteristics in both xml - schema and relational schema , a semantic constraints - preserved algorithm is proposed which can realize the bi - directional schema mapping between rdb and xml through a formalized description of xml based on regular tree and a general expression for relational schema based on direct graph approach
保留语义约束的xml与rdb双向静态数据转换技术现有研究大多采用dtd ( documenttypedefinition ，文档类型定义)作为xml的模式描述语言，并且在模式映射过程中丢失语义约束信息，本文分析了xml - schema ( xml - schema采用与dtd完全不同的语法，数据描述能力更强同时也更为复杂，已被w3c确定为替代dtd作为xml模式描述语言的标准)及关系模式的语义约束特征，通过基于正则树的xml形式化描述方法以及基于有向图的一般关系模式表示方法的研究，建立保留语义约束的xml - schema与关系模式的双向模式映射算法，实现了xml与rdb的双向数据转换，较好地解决了xml与rdb在静态数据转换层面的数据集成问题，可有效满足企业大量rdb数据面向xml的发布以及与日俱增的xml数据存入rdb的应用需求。 | | 5. | 1284 - 1994 improves the rate of data transfer of parallel interface greatly and provides bi - directional data transfers it makes the demand for data is no more the bottleneck of peripheral performance at the same time , due to the characteristic of bi - directional data transfer , the host can identify the mode of peripheral sc the problem of mistake operation on unsupported device can be avoided
Ieee1284 - 1994标准使并行接口的数据传输速度得到了极大的提高，并且支持双向数据传输。这使得对数据的需求量不再成为外设的性能瓶颈，同时由于双向数据传输特性，所以主机能识别外设的型号，这样就不至于对不支持的设备误操作。 |
