"What's in a name?" -W. Shakespeare
It's like being hit by way of a bus; this ebook is a significant learn. I needed to learn it two times to easily comprehend the reasoning in the back of the name "Enterprise structure and Integration".
This isn't really a customary technical ebook. it's a number of suggestions, facts, demanding situations and strategies packed in just approximately 360 pages, yet when you are performed examining it you're feeling such as you simply comprehensive analyzing Leo Tolstoy's conflict and peace.
Only after examining the entire ebook, you are going to notice that sum of the items, and the data got in the course of the booklet, is what's going to make you begin appreciating the booklet, and its worth; that is the manufactured from collaboration among the authors of every bankruptcy, and the labor through Wing Lam to place it together.
Of path there have been a few questions in my brain, similar to to why they proposal it was once very important to speak about RFID, particularly within the final bankruptcy of the final part Hmmmmm, additionally why the "Architects" did not see the downfall of the SOA and it truly is shortcomings together with its lack of ability to convey on ROI.
I am an organization believer that architectural books shouldn't be certain via time and house yet signify suggestions, rules creations which are acceptable regardless, so consequently I recommend that the name be replaced to "Making of an company Architect and an Integrator", which i feel what this ebook intends on providing. And to reply to Mr. Shakespeare's query I easily say: Everything.
Best Fishes and thanks for examining.

Example text

Service integration: A common set of reusable services that are made available to other applications. For example, a service to obtain a customer’s status may be created that can be called by any other application within the organisation. Such services are usually built from a set of specific application functions. Process integration: The definition of business-process or workflow models from which reusable services are called. Process integration is particularly relevant in collaborative contexts, such as B2B, where there business processes drive interactions and transactions between business partners.

Another way of looking at integration is in terms of the level at which integration occurs. Integration can occur at five levels, namely, presentation, data, application, service, and process integration, as shown in Figure 4. Each successive level of integration represents what might be considered a more advanced form of integration. • • • Business events generate messages that are sent to all the appropriate IT systems Upon receipt of the message, the IT systems update information held locally A real-time (and typically sophisticated) messaging infrastructure is used to support communication between IT systems Information between IT systems is kept up to date Many financial organisations, for example, deploy event-driven architecture to enable realtime trading and transaction processing.

On the other hand, dependencies are created as the frequency of changes is higher and release cycles are shorter. If the components are too modular, the benefit of reuse is lower, and run-time and maintenance overhead increases because many small functions have to be reused, not just one. Another aspect that should be considered when designing reusable software components is the level of specialization. If only very specialized components are developed, the potential for reuse is low because only few applications or users need this very specialized function.
