Grid Technology In Enterprise Application Integration

With the development of enterprises competitive globalization, enterprises must improve the level of information themselves in order to satisfy the need of the modern enterprises business variety and the fierce competition. At present, EAI is the main method that enterprises advance information reform, appearance of the Grid technology provides a new mode for EAI, its openness and standard provides the best mode for application system integration based on the Grid Service. It is not relative to flat form and language, which is convenient for enterprise application integration dynamic and mutual operation in system.In the paper, we research the advantage of EAI based on OGSA. It mainly discusses the following aspects:1. Frame of EAI based on OGSAIn allusion to the shortcoming of existent EAI, we reform EAI based OGSA, which is EAI-based-GS. Relative to the past services binding, EAI-based-GS has advantage: can connect Grid Services dynamically, when users require, it looks for the suited service, and deletes the connection when service is end.2. Actualization schema of application system integration in Bengbu tobacco factory We study how to manage system resource (service) in EAI-based-GS frame, and whenusers require, how to find Grid Services. We provide a solution for connecting heterogeneous systems according to the actual instance.3. Resolution schema of eliminating isomerous character in Bengbu tobacco factory We use XML to eliminate isomerous character of data model from various system; useSOAP and WSDL to eliminate isomerous character of groupware.
