摘要
业务部门信息系统之间数据的自治性、分布性和异构性,使得数据交换成为必然需求。角色是数据的提供者与消费者,现有数据交换方法中很少有基于角色来考虑数据交换的。由于各企业角色专业知识与数据格式不同,角色之间又存在着各种各样的联系,文中提出一种基于角色流的数据交换技术,在已有建模技术中引入角色的思想,且保证数据质量的前提下更好地表达角色之间的各种关系,提高角色协同活动的执行效率,最大限度地发挥数据应有的价值,为企业科研、生产、管理提供可靠支持。
Autonomy,distribution and heterogeneity of data between information systems of business units,make data exchange become an inevitable demand.Role is data providers and consumers,the existing data exchange methods do not consider the role-based data exchange.Due to the role of enterprises professional knowledge and data format difference,between the roles there are a variety of contacts,present a data exchange technology based on role-flow,introduce the role of ideology into the existing modeling techniques,the premise of ensuring data quality to better express the relationship between the roles,to improve the role of collaborative activity execution efficiency,to maximize the data value,for the enterprise of scientific research,provide a reliable support for production and management.
