Messaging Systems
Introduction to Messaging Systems
How does one application communicate with another using messaging?
How can two applications connected by a message channel exchange a piece of information?
How can we perform complex processing on a message while maintaining independence and flexibility?
How can you decouple individual processing steps so that messages can be passed to different filters depending on a set of conditions?
How can systems using different data formats communicate with each other using messaging?
How does an application connect to a messaging channel to send and receive messages?
Messaging Channels
Introduction to Messaging Channels
How can the caller be sure that exactly one receiver will receive the document or perform the call?
How can the sender broadcast an event to all interested receivers?
How can the application send a data item such that the receiver will know how to process it?
How can a messaging receiver gracefully handle receiving a message that makes no sense?
What will the messaging system do with a message it cannot deliver?
How can the sender make sure that a message will be delivered, even if the messaging system fails?
How can you connect an application to the messaging system so that it can send and receive messages?
How can multiple messaging systems be connected so that messages available on one are also available on the others?
What is an architecture that enables separate applications to work together, but in a decoupled fashion such that applications can be easily added or removed without affecting the others?
Message Construction
Introduction to Message Construction
How can messaging be used to invoke a procedure in another application?
How can messaging be used to transfer data between applications?
How can messaging be used to transmit events from one application to another?
When an application sends a message, how can it get a response from the receiver?
How does a replier know where to send the reply?
How does a requestor that has received a reply know which request this is the reply for?
How can messaging transmit an arbitrarily large amount of data?
How can a sender indicate when a message should be considered stale and thus shouldn’t be processed?
How can a message’s data format be designed to allow for possible future changes?
Interlude: Simple Messaging
Introduction to Simple Messaging Examples
Message Routing
Introduction to Message Routing
How do we handle a situation where the implementation of a single logical function (e.g., inventory check) is spread across multiple physical systems?
How can a component avoid receiving uninteresting messages?
How can you avoid the dependency of the router on all possible destinations while maintaining its efficiency?
How do we route a message to a list of dynamically specified recipients?
How can we process a message if it contains multiple elements, each of which may have to be processed in a different way?
How do we combine the results of individual, but related messages so that they can be processed as a whole?
How can we get a stream of related but out-of-sequence messages back into the correct order?
How can you maintain the overall message flow when processing a message consisting of multiple elements, each of which may require different processing?
How do you maintain the overall message flow when a message needs to be sent to multiple recipients, each of which may send a reply?
How do we route a message consecutively through a series of processing steps when the sequence of steps is not known at design-time and may vary for each message?
How do we route a message through multiple processing steps when the required steps may not be known at design-time and may not be sequential?
How can you decouple the destination of a message from the sender and maintain central control over the flow of messages?
Message Transformation
Introduction to Message Transformation
How can existing systems participate in a messaging exchange that places specific requirements on the message format, such as message header fields or encryption?
How do we communicate with another system if the message originator does not have all the required data items available?
How do you simplify dealing with a large message, when you are interested only in a few data items?
How can we reduce the data volume of message sent across the system without sacrificing information content?
How do you process messages that are semantically equivalent, but arrive in a different format?
How can you minimize dependencies when integrating applications that use different data formats?
Interlude: Composed Messaging
Introduction to Composed Messaging Examples
Synchronous Implementation using Web Services
Asynchronous Implementation with MSMQ
Asynchronous Implementation with TIBCO ActiveEnterprise
Messaging Endpoints
Introduction to Messaging Endpoints
How do you encapsulate access to the messaging system from the rest of the application?
How do you move data between domain objects and the messaging infrastructure while keeping the two independent of each other?
How can a client control its transactions with the messaging system?
How can an application consume a message when the application is ready?
How can an application automatically consume messages as they become available?
How can a messaging client process multiple messages concurrently?
How can multiple consumers on a single channel coordinate their message processing?
How can a message consumer select which messages it wishes to receive?
How can a subscriber avoid missing messages while it’s not listening for them?
How can a message receiver deal with duplicate messages?
How can an application design a service to be invoked both via various messaging technologies and via non-messaging techniques?
System Management
Introduction to System Management
How can we effectively administer a messaging system that is distributed across multiple platforms and a wide geographic area?
How can you route a message through intermediate steps to perform validation, testing or debugging functions?
How do you inspect messages that travel on a point-to-point channel?
How can we effectively analyze and debug the flow of messages in a loosely coupled system?
How can we report against message information without disturbing the loosely coupled and transient nature of a messaging system?
How can you track messages on a service that publishes reply messages to the Return Address specified by the requestor?
What happens, though, if a component is actively processing messages, but garbles outgoing messages due to an internal fault?
How can you keep 'left-over' messages on a channel from disturbing tests or running systems?
