数据访问控制 meaning in English
data access control
Examples
- The thesis use role based access control model , design a set of logical data model and propose the basic algorithm for access database
在数据访问控制方面采用了基于角色的安全策略,设计了数据访问控制的逻辑模型和基本方法。 - Data service layer , including data access service layer , data access control layer and data access security mechanism , works to ensure the security and control of the access of service handling to the data in enterprise information platform
数据服务层包括数据访问服务层、数据访问控制层和数据访问安全机制，由数据服务层来保证业务处理对企业信息平台数据访问的安全和控制。 - Then we propose an xml data access control system which uses extended xpath and user or user group information to define the access object . we describe the architecture , the subject , object , access rules and the different levels of the rules . and we also illustrate the access control process with an example
在基于xml的数据访问控制方面，本文提出了一个利用用户、用户组数据和扩展后的xpath进行访问对象描述的xml数据访问控制方案，对该方案的架构，访问控制的主体、对象、授权规则和规则级别等进行了详细的介绍，并给出了应用示例。 - Because the existing data model can ’ t work perfectly with given application , this paper brings forward domain data model ( ddm ) . ddm ’ s structure is more fit for given applied field . it helps us to design and develop mis easily and it can solve the problem of data access control on applied layer
本文针对现有的数据模型与具体的应用结合不紧密的特点,提出了构造更贴近具体应用领域的域数据模型,用于帮助mis的设计和开发,解决mis开发过程中,应用层面的数据访问控制的难题。 - General compressing technologies are not proper in some circumstances for the receivers are always required to decompress the data completely to manupulate the original data ( querying , validating etc . ) . the embedded document structure of xml also makes it difficult to perform access control because the traditional file level access control systems could not fulfill the requirement of element or attribute level access control . in the paper we first present a scheme for xml - based data exchange which is an xpath - query - friendly compressor for xml
压缩技术是提高交换效率的一种方法，但接收方需要对压缩文档完全解压才能够执行进一步的操作，在很多应用中这种方式并不适用，这就提出了如何在高效压缩的同时在压缩后的xml文档上进行查询等操作的问题；另一方面，由于xml文档的层次结构的特殊性，传统的文件级别的访问控制已经不能适应在元素、属性的级别上进行访问控制的需要，所以对只需要访问部分xml文档内容的用户进行有效的数据访问控制也是xml数据访问控制面临的一个问题。
