Method for interoperating distributed heterogeneous information systems

Abstract

The invention discloses a method for interoperating distributed heterogeneous information systems. By adopting the method, a unified mode can be adopted to realize service collaboration among any information systems. The collaboration can be realized inside organizations, among the organizations or in a trans-regional distributed and hierarchical mode. In the method, data exchange and data sharing which are carried out by service collaboration of the information systems are concluded to data and a service which serve as two interoperation resources; an interoperation strategy realizes description on a collaboration service logic and a collaborative strategy of the information systems by four operations mainly for the interoperation resources, i.e. data extraction, data transformation, data encapsulation and data export; and standardization of a service collaboration user interface and automation of a collaboration service are realized by executing the interoperation strategy. The interoperating systems realized by method can have three adjacent, communicated and separated relations and three simple, symmetrical and hierarchical interoperating modes. By adopting the three relations and the three modes, the trans-regional interoperation of the complex distributed information systems can be realized by adopting the unified mode.

Description

1. Technical field [0001] The present invention belongs to the field of information technology (IT), and in particular relates to the realization of interconnection between multiple related information systems (the multiple information systems involved can be homogeneous or heterogeneous; they can be distributed and deployed according to the requirements of business organizations) An interoperable approach to business collaboration. 2. Background technology [0002] With the rapid development of information technology, a large number of various production, operation and management businesses in the organization have been gradually upgraded from traditional manual operations to information technology-based operation methods, and the establishment of corresponding information systems for various businesses has become a reality. It has become an important means for large organizations, especially industrial organizations, to enhance their market competitiveness. However, due t...

Problems solved by technology

[0005] However, due to the extremely complex business collaboration requirements, the application of the above technologies can only develop corresponding information system collaboration components for the special needs of individual business collaboration. This business collaboration implementation method has the following problems:

[0006] (1) In the process of continuous development and improvement of the organization's management, business collaboration requirements will continue to evolve, and the evolution direction and trend are difficult to predict. Simply use the above technologies to develop information system collaboration components for the special collaboration needs of individual businesses to achieve business collaboration , will make the adjustment of business coordination very difficult, and cannot meet the needs of business management changes

[0007] (2) When the information systems of various businesses in the organization need to carry out business collaboration, there will be a lot of business collaboration components developed in this way, and it is proportional to the square of the number n of businesses, and both development and management will change. In particular, the business data access authorization will be managed and controlled by the business information system, which does not conform to the business organization practice of authorization by position and responsibility

[0008] (3) When business collaboration between organizations is required, in order to improve the automation level of business collaboration, the business collaboration components developed in this way can only run as background services, and the business collaboration components between organizations cannot be used by multiple It is also difficult to adapt to the requirements of management autonomy between organizations and information exchange in a standardized manner.
