为提高数据共享效率，针对关系型数据提出一种基于Web Services的服务动态发布方法并抽象出CBC服务动态发布模型。该方法通过图形化界面选择数据库，构造查询约束信息，利用CBC服务动态发布模型将所构造的约束信息转化为系统所能识别的查询语句并发布为服务。用户通过服务查询器、验证器来查询验证服务的有效性，对满足需求的服务以Web Services的形式实现跨单位和跨数据库的集成调用。实验结果表明该方法可以有效地提高数据共享效率，且有利于异构系统之间的数据交换。

In order to improve the efficiency of data sharing , CBC dynamic service publishing model was proposed for relational data, which is based on Web Services dynamic service publishing method .This method selects the database and constructs query constraint information through a graphical interface , converts the constructed constraint information into the query statements that can be recognized by the system and publishes them into services with the CBC dynamic service publishing model .Users can que-ry services through service querier , verify their effectiveness through service validator , integrate and call the qualified services cross-department and cross-database with the format of Web Services .Experiments show that the method can effectively improve the efficiency of data sharing , and benefit the exchange of data between heterogeneous systems .
