Abstract: A state management sub-system that assists in transmitting and processing documents and messages between two applications in a sequentially correct order through an integration server is disclosed. The state management subsystem analyzes the message and enters state information about the message into a state management table. Once the message is transformed the state management subsystem check the status of the message in the state management table, and checks all waiting parameters. Depending on the status of the check, the state management subsystem changes the state of message in the table. Only when all messages have passed the waiting parameters check is a message posted to the destination system.

Abstract: A linking system that assists in managing the linking of entities contained in messages between two business applications is disclosed. The linking system also assists in updating entities between two business applications when an entity is updated in one application. The linking system takes each entity and places identifying information for the entity in a record in a first table. The system then creates in a record in a second table indicating that the two records in the first table are linked. The linking system also can remove links or records from the tables, and can return to a user a list of records that are linked together.

Abstract: A method for updating a database that combines the advantages of both the migration and incremental approach may resolve some of the problems associated with earlier methods. This may be accomplished by a methodology which incrementally updates new data while using the migration approach to create an entirely new schema. Such a method might compare the metadata from both the existing database and the data update to generate a new schema and integrate new data into the database.
