A messaging system includes a message bus and a first processing device. The message bus is adapted to transmit a first message. The first message includes a second message, and the second message includes at least a first command. The first processing device is coupled to the message bus. The first processing device includes a message interface adapted to receive the first message and extract the second message independent of the first command. An input queue is adapted to store the second message. A message interpreter is adapted to retrieve the second message from the message queue and decode the second message to identify the first command. A method for communicating messages includes transmitting a first message over a message bus. The first message includes a second message, and the second message includes at least a first command. The first message is received and the second message is extracted independent of the first command. The second message is stored in an input queue. The second message is retrieved from the message queue. The second message is decoded to identify the first command.
A method, system and computer program product to isolate information related to performing a manufacturing process, called a configuration document, from the context in which the information is used. A context/configuration association can be independently established between a process context and a context-free configuration document including instructions for performing a manufacturing process. Because the context/configuration association is independent of both the process context and the context-free configuration document, the context/configuration association can be independently reviewed and approved without affecting other process contexts or configuration documents.
A process, architecture, and computer program product for using the inheritance features of an object-oriented system to enable multiple programmers to modify different behaviors of an object concurrently. A first method and a second method to be performed on the object are identified. The first method is developed in a first application having a first subclass of the object's class. A first application-specific object is an instantiation of the first subclass. The second method is concurrently developed in a second application having a second subclass of the object's class. A second application-specific object is an instantiation of the second subclass. Invoking the first method performs the first method on the first application-specific object, such that the object communicates as if the first method were performed on the object. Modifying the first method does not affect the second method, and vice versa.
The invention relates to a method for querying a database with database contents that have a database structure. The query is made in a query structure, which differs from the database structure in that the query structure and the database structure reference a standard structure, and the reference logic is at least partially transmitted together with the query and/or is at least partially present in the database.
Provided are a method, system, and article of manufacture for processing requests in a server side application. The server side application receives a request in a communications protocol from a client. The server side application modifies the request to create a communications protocol independent request. The server side application generates a response by processing the communications protocol independent request. Subsequently, the server side application sends the generated response in the communications protocol to the client.
