A Business of modern government agencies and public institutions have been performed mainly using information systems. And information systems have been built In many places as the agency process information projects continuously. Information systems are built and used actively depending on the purpose of their task-specific goals. They also provide a number of services. It refers 'E-government' that performs administrative work of public sector based on the e-business information systems. A lot of e-government information systems are built and operated independently, depending on the business and policy. But sometimes it happens frequently that one work is operated separately by a number of information systems or a variety of tasks are operated by just one information system. The need for system interoperability and sharing information about the efficient management and processing of specific tasks and information is growing.
In this paper, I propose a method to ensure the reliability of data for information linking framework as a infrastructure of collaborative environment which is distributed and independently operated between information systems for their interoperability. This is a framework for data interoperability of the heterogeneous information between distributed information systems in the e-government environment. This framework suggests a data quality management technique for secure the reliability and improve the availability of the data which want to interoperate. Also it proposes a security management of data interoperated for security processing of the e-government information systems. A brief look at the features of this system is as follows. The quality can be measured at each stage of data extraction and loading. And data integrity, validity, uniqueness and consistency
management is possible. It can be applied to a wide variety of platforms because it is based on GUI implementation of Java. And it is easily scalable because the source and the target that you want link can be implemented in a variety of ways by a multi-agent based management. Above all, this framework can solve the heterogeneity of different kinds of data, that appear when linking distributed data, based on user-defined business rules which general ETL cannot provide. Also, it allows dynamic creation and management of the user-defined rules. This is to cope with the distributed real-time information associated environment that the data value is not constant and the amount of data require frequent changes and refining increase.
