Enterprise Application Integration by David S. Linthicum
The majority of failed application development projects over the past decade resulted from overly complex distributed computing architectures.
Interest in EAI is driven by a enterrise of important factors. In seeking to integrate links, the manager may also encounter additional problems such as:. Open to the public ; QA Available also in a print edition. Until recently, architecture at the enterprise level had been virtually nonexistent.
Integrating applications both processes and data within the same machine rarely created a problem beyond some additional coding. You will also find an in-depth explanation of the four major types of EAI: EAI is able to take many diverse systems and bundle them in such a way that they appear–and function–as a monolithic and unified application see Figure 1.
Inter-Enterprise Application Integration Ch. It must be measured enterprise by enterprise. Defining the Value Step It does, however, urge caution and a broad perspective. With the pressures of a competitive business environment moving IT management to shorter application life cycles, financial prudence demands that IT managers learn to use existing databases and application services rather than recreate the same business processes and data repositories over and over see Figure 1.
Enterprise Application Integration
Obstacles, davie as interdepartmental turf battles and constantly changing business requirements, have little to do with technology but a lot to do with hindering solutions. Inevitably, this reality demonstrated that the system was built without much thought having been given to the requirements for information sharing. As a result, there were no open application programming interfaces APIsopen architectures, or other mechanisms that allowed for ready access to the processes and data that existed within these stovepipe systems.
To justify its expense, a technology must demonstrate its usefulness.

Series Addison-Wesley information technology series Subjects Business enterprises — Data processing. Linthicum is an internationally known distributed-computing and application integration expert who speaks at popular technical conferences throughout the United States.
Put briefly, EAI is the unrestricted sharing of data and business processes among any connected applications and data sources in the enterprise. Open to the public ; Using this scenario, linthiicum and developers are able to bundle applications by using their user interfaces as a common point of integration also known as screen scraping.
Ultimately, finances are a prime concern. Although not preferred, it may be the only solution you have in many instances. But IT managers attempting integration face daunting challenges–disparate legacy systems; a hodgepodge of hardware, operating systems, and networking technology; proprietary packaged applications; and more.
Parramatta South Campus Library. Anupriyo rated it it was ok Aug 19, Mohamad Andriyan added it Mar 03, Les Linthicmu rated it really liked it Nov 27, Alexei rated it liked it Nov 14, For example, when integrating a custom accounting system running on Windows with a custom inventory control system running on the mainframe, you may select a message-queuing middleware product to allow both systems to share davod.
Read, highlight, and take notes, across web, tablet, and phone. The book describes in detail the middleware models and technologies that support these different approaches, including:. With Safari, you learn the way you learn best.
enyerprise Middleware provided developers and application architects with the ability to bridge many different systems, bringing them together to form virtual systems. Given these significant limitations, it follows that EAI represents a very different method of application integration than that using traditional middleware see Figure 1.
For example, if increasing sales is one of your goals, sharing inventory information with the sales order-processing system may allow sales to operate more linnthicum and thus help realize that goal. Saurabh rated it it was amazing Mar 28, Using these interfaces, developers are able to bundle many applications together, allowing them to share business logic and information. In effect, they aplication demanding that ways be found to bind these applications into a single, unified enterprise application.
While many different types of technologies can do this, message brokers seem to be the preferred solution. While these benefits do exist to a certain degree, distributed systems, though architecturally elegant, are difficult to implement.
