The invention discloses a method and system for flowing, distributing and displaying of data in an information system. The method includes the steps that the data referred by process nodes of a business process are collected, the collected data are stored in a database, and correspondence is carried out on an entity name in the collected data and a standard entity name exiting in the database according to a system code and a name; corresponding distribution relationships between a grid entity and entities of application systems are made on the basis of the data correspondence; repeatedly-distributed data entities and flowing relationships of the grid entity between the application systems are obtained according to the entity correspondence distribution relationships, wherein the repeatedly-distributed data entities are flowing-free entities; a data framework displaying platform is built, and the flowing relationships of the grid entity between the application systems in the third step are dynamically displayed into flowing of the data entities between the systems with the Flex technology. By means of the method and system, all-dimensional current situation combing, multi-view data displaying, rapid problem analysis positioning and powerful quality improvement control over the data are achieved.
