Levels of Enterprise Application Integration

Levels of Enterprise Application Integration

When it comes to the levels of enterprise application integration, there are basically four levels. In this section, you will explore each of the levels in greater detail. Let’s get started!

1. Business Process Integration

The very first level of enterprise application integration is the business process integration. In this integration, businesses make strategies to automate their processes, achieve the set goals, and enhance overall performance.

To integrate business processes, there are three ways. It includes:


The data is transferred from the business process management software to a different system. An example of this integration is the transfer of the data of a successful candidate to the HRM.


In this integration, the data is transferred from a system to a business process management software.

Process Trigger:

An event taking place in a particular system may trigger a process in the business process management software of the enterprise. On the basis of an event, the process triggering may automate the process execution.

2. Data Integration

The next level of enterprise application integration is data integration. In this integration, the users can easily share information between applications and maintain complete transparency.

In order to convert the output of applications to data, most application integration relies on specialized codes. These concepts form the backbone of all enterprise application integration solutions.

3. Communications-Level Integration

This integration is an approach leveraged by organizations to achieve business process and data integration. It allows the applications to effectively and efficiently communicate with each other.

The communications-level integration helps in specifying how exactly the communication takes place. To accomplish the tasks, APIs are usually used.

4. Presentation-Level Integration

Presentation-level integration combines a number of applications into a single one and ensures a standard interface. In order to achieve this integration, companies can make use of middleware technology and solutions.

Moreover, this integration also creates a virtual intermediary and facilitates the easy collection of data. Then the data is distributed across different applications. The presentation-level integration is considered to be a suboptimal way of integrating and accessing data.

Models of Enterprise Application Integration

There are various models of enterprise application integration available. So, based on the unique objectives and requirements of your business, you can make the right choice. Each model comes with a distinct framework and methodology for the improvement of communication and data management.

Let’s explore the top 5 models of enterprise application integration.

1. Hub-and-Spoke Model

Hub-and-Spoke Model
The Hub-and-Spoke model comes with a central component that facilitates the integration of different features. It allows for connecting every single element effectively.

This model serves as a central hub, responsible for sending, receiving, and reformatting data across different destinations.

2. Point-to-Point Model

Point-to-Point Model

In this model, the developers build unique connector programs for individual integration. Every connection needs a distinct script to send, process, and translate the data.

The point-to-point model is an ideal option for enterprises having minimal services. It provides greater flexibility to the users by enabling them to easily add an abstraction level.

This model is both reliable and fast. Moreover, it is also inexpensive. So, implementing the model can help you save more in the long run.

3. Middleware

Middleware is a model that acts as a connective tissue between users, data, and applications. It enables the developers to effectively build and deploy applications.

The best thing about middleware is that it provides you with a lot of options to choose from. The most common types include transaction processing monitors, message brokers, application-server middleware, message-oriented middleware, and more. The middleware helps in the creation of a connection pool and allows users to access backend data faster.

4. Enterprise Service Bus

Enterprise Service Bus Model
The enterprise service bus model makes use of a service-oriented architecture. It provides excellent interconnectivity and allows smooth communication between different network applications. It develops an indirect connection between systems and facilitates the development of simple applications.

This model is suitable for implementing complex and large systems. It helps you get rid of the potential bottlenecks of a single hub.

A major benefit of leveraging this framework is that it is highly scalable. That means you can easily add or remove applications as per your requirements with minimal changes. Moreover, the enterprise service bus model does not require the constant attention of the developers.

5. Microservices

API Gateway
Microservices basically refer to an architectural design approach used by developers to build applications. In this approach, the developers have the flexibility to break down the extensive program into different independent and smaller components. Each of the components comes with unique responsibilities.

As a result, when some services fail or require modifications, all the other services remain undisturbed and functional. Moreover, upsizing or downsizing applications across different devices and platforms is simple and easy.

6. Enterprise Integration Tools

Have you decided to opt for enterprise application integration? In that case, you must be wondering which tools to use. Some of the top tools you can leverage are listed below.

EAI vs. ESB vs. SOA

EAI vs. ESB vs. SOA

By now you must have a basic idea about enterprise application integration and its relevance among modern organizations. Next, let’s explore the top app integration approaches.

Enterprise service bus or ESB refers to an integration model. It allows developing services and improving their interactivity through the use of an API. ESB serves as a messaging backbone, responsible for message format transformation, delivery of messages, and routing.

Service-oriented architecture or SOA is an approach in which the software resources of an enterprise become discoverable on different services and networks. Each of the services is designed to achieve a specific objective and perform different work units. They operate within a distributed systems architecture.

EAI, SOA, and ESB, all focus on integrating enterprise applications. However, their underlying architecture differs. While SOA promotes the use of reusable services, EAI is ideal for point-to-point integration. On the other hand, ESB is the perfect choice for creating a messaging infrastructure that connects loosely decoupled services.


By now, you must have a complete idea about the enterprise application integration. Its demand is likely to increase even more in the near future. EAI helps connect all the applications of the organizations and allows streamlining their operations.
