- Example Sentences:
| 1. | Introduce searching engine technology of " event inspection " and define the modular description language in respect of its intrusion patterns , as well develop the corresponding rules parser
采用了“事件检测”引擎技术，并定义了一套入侵特征模式描述语言及相应的规则语法解释器。 | | 2. | Therefore new attacks can be logged in modular description language and added to the attacks logging database . the description languages together with the event inspection function make the system ' s expandability and upgrading possible . 3
这样，可以用模式描述语言描述新的攻击并增加到攻击特征模式库中，同时增加新的事件检测引擎来识别此攻击，保证了系统的可扩展性要求，方便升级。 | | 3. | 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。 |
