But what difference are the purpose, speed and direction and amount of data that are transformed and placed within the unified view from the external sources. Process-level integration mainly deals with building enterprise-wide business workflows and processes and incorporating existing applications into those processes. EAI middleware acts as the workflow engine integrating applications in near real time, passing small amounts of data through message queues and a series of stages.
EAI tools provide much more complete workflow capabilities than ETL tools, which provide simple workflow. EAI tools, and especially their workflow components, provide very sophisticated GUI development environments that enable the design and management of very complex business processes.
Here transformations are focused on ensuring a common understanding of the context and meaning semantics of the data involved within the message, the more likely a proven EAI is more appropriate. With regards to data integration, ETL tools and also next generation ETL clearly holds an advantage whether in batch or real time. Synchronizing data between two applications involves a lot more data manipulation than simply moving data from point Source to Target.
Typically, enterprise data warehousing projects require you to move large amounts of data within relatively small windows of time. Also since ETL tools were born out of the relational database world, and thus are adept at performing SQL oriented transformations. At designated intervals of time, ETL solutions ask the source application if anything has changed, and if so, push the updated data to the destination database.
If you pull the data too frequently, you burn resources unnecessarily. If you don't pull it frequently enough, you risk having inaccurate data. Instead, you need a workflow triggered by a specific event.
An application integration solution that incorporates webhooks can constantly listen for changes in the source system. When a request comes in that requires a particular data set, webhooks immediately integrate the necessary data to eliminate polling intervals and provide data in real-time. While ETL can't address the scenarios outlined above, an integration platform as a service iPaaS solution can fulfill your modern enterprise data needs.
ArcESB provides an intuitive, drag-and-drop workflow canvas that gives you the power to quickly build application integration processes — without coding. It can power all your complex integrations in one place with capabilities for B2B systems integration, advanced business logic, data validation, and real-time integration through webhooks.
It also simplifies workflow management, providing you a central location to orchestrate your integrations, complete with:.

So-called business integration through an ESB and so-called application integration through old EAI differ only by marketing, as each of them used to cope with business-related data integration. Your insistence on this point is frustrating. The technology is not the same at all.
You seem quite stubbornly to be ignoring a point that a lot of us are trying to make, which is that there are real differences in software design, implementation methodology and data process that are involved. In my mind, the business encapsulation introduced by the use of web services in ESB is a simplified way of encapsulating data access. This was previously done through ad hoc non-standard adapters and internal intermediary data models.
Traditional EAI implementation involved time-consuming data mapping, adapter configuration or worse adapter design. In the end we have to design IT processes from internal to applications to trans-applications as aligned on enterprise business processes…. And there is always a need of good thinking and planning about end-to-end information circulation between stakeholders and participants in overall processes.
But there is nothing fundamentally new with those tools. For example, first generation EAIs were built on top of proprietary application servers. Today, that does not make sense anymore with J2EE defining quite precisely how a java application server is supposed to work. Editors can even develop on top of free java application servers. At least not as much as u do….
I follow you. With some side effects to be discussed. I would have to agree that ESB, as Roland defines it, is not standards-based. A good number of ESB solutions on the market are standards-based, though. NET version, which runs quite well in many contexts, but is definitely proprietary. In my last message, I pointed that you were yourself —as a well-known ESB specialist— stating differences in architecture between different ESBs, some centralized and some not.
After all standards are made to design a common competition field were fighters may fight each with its own weapon. And I think you would admit that over these two tier of architecture and of standards there is a third business tier which is the root even if above. Standard may up to now ease implementation and lighten costs, but lack of standardization keeps price higher than affordable and try to enforce the idea that you need only one solution for all your different integration needs provided that you sink all your integration budget in that only solution.
Secondly I think that standardization keeps only a syntactical definition, not a functional one. When talking about services, I feel a general confusion between the capability to allow service use, and the actual definition of services.
Because this is related to the way each company differenciates itself on the market and takes a bonus on its competition either through price or through innovation or renew its business permanently.
And to the way companies decide their organisation and share of work for each of its skills. And to the way companies choose their IS solutions to fit diverse skills needs. So making an argument of business standardization through so-called service standards appears to me something dubious and questionable. Standards in other industries are also made in mind for end-user benefit and business benefit, not just for the benefit of the industry.
EAI serves as a system that can provide a business service to simplify information data between diverse applications, which makes it possible to easily integrate them when needed. This discipline of integrating applications and data within the enterprise has been a critical component of today's enterprise strategies. In fact, many vendors offer EAI suites that provide cross-platform, cross-language integration solutions. Today - Yesterday - Total -.
