Application Integration: A Beginner’s Guide

Integrations have become a new norm in the tech world, with more than half of all services relying on third-party integrations.

Even the businesses that use internal software prefer using an integrated system that helps them fetch the necessary information, all in one place.

Application integration is at the heart of this data exchange and added services, as it allows a user to be significantly more efficient without having to shuffle through multiple interfaces to complete a process. It’s like bringing different things together to make it work.

So what is Application Integration? What are the types of app integrations? More importantly, why does it matter in a mobile app development process? Well, these are some of the many questions that we are going to answer throughout this guide.

Without further ado, let’s start by understanding the definition of Application Integration.

An Overview of Application Integration

Application integration refers to the process of integrating multiple applications and processes into a single app that can be used by the user to get things done in real time.

It is often kept in line with the data integration process; however, it is more comprehensive and gives more flexibility than simply compiling data for consolidation.

App Integration is like making sure all the interconnected apps can understand each other’s language and work in harmony, just like a team that has a synchronized course of action.

Application integration tends to connect different applications together, allowing them to trigger processes on their own for a larger process to be completed and the objective to be achieved.

The best example of app integration can be a payment application where you have a single interface that not only is connected with the banking app to fetch your personal account information, but it is also connected to a payment gateway that allows the transfer of funds.

However, that is not the only way app integration works. There are several more examples given below to give you a better understanding.

Application Integration Examples

Why is Application Integration Important?

Application integration is often misunderstood to be a small part of the process. In reality, it is one of the most important things to take into consideration when building an app.

From fetching commands to completing the process and returning the result to a single interface, the application integrates and adds a lot of convenience to the overall functioning of your app.

There are several reasons why application integration is considered a crucial part of the process. Some of the most crucial ones you must know include seamless information flow between different processes.

Since everything is interconnected in the functioning of the application, the business processes are streamlined to the extent that automation can be achieved for the majority of the involved processes.

Application integration becomes further important for a business as it allows an app to be ready faster.

The time-to-market for your application is significantly reduced when you choose app integration rather than building functionalities manually. It saves time and makes it more efficient to work.

Last but not least, the power of app integration allows you to be more forward with the latest technologies and features.

Since these applications are already available in the market, integrating them can help you leverage the audience that they have gathered without your developers having to struggle with coding and testing the outcome.

Types of Application Integration Used in Development

While it makes a lot of sense to use the app integration, you must understand what type of integration will fulfill your requirements.

You see, the idea of integration simply refers to joining two types of apps or processes together to work in a synchronized manner.

However, when combining two or more applications, you need to understand what kind of arrangement will support the proper exchange of data between the

But what are these types? Well, let’s discuss all of that below:

1. Point-to-Point Integration

In this approach, you establish direct connections between specific applications for particular tasks.

Keep in mind that as the number of applications increases, managing these connections can become complex.

2. Hub-and-Spoke Integration

With this method, you use a central hub or intermediary to connect all your applications.

Instead of creating direct links between each application, they connect to a central hub. It then distributes data and services efficiently.

3. Middleware Integration

Middleware serves as an intermediary layer between your applications, aiding communication and data exchange.

It offers services like message queuing, data transformation, and routing. Think of it as a way to simplify interaction.

4. Data Integration

Focus on ensuring that data from various sources is accessible to your applications.

This involves merging, transforming, and cleaning data to offer a unified and consistent view across your systems.

5. Business Process Integration (BPI)

Integrate processes and workflows of your different applications to streamline end-to-end business processes.

It’s about optimizing how your systems work together to improve overall efficiency.

6. API Integration

APIs define how your software components interact. Use these interfaces to connect your applications and exchange data and functionality seamlessly.

7. Cloud Integration

Connect your on-premises systems with cloud-based applications and services. This combination allows you to take advantage of both environments effectively.

8. B2B Integration (Business-to-Business)

Connect with other businesses or organizations to enable smooth data and process exchange. Useful for collaboration in supply chain management and similar scenarios.

9. IoT Integration (Internet of Things)

Link devices, sensors, and data streams to your applications and systems. This real-time connection enables data collection, analysis, and automation in various contexts.

10. EAI (Enterprise Application Integration)

EAI covers a wide range of integration techniques and tools to connect various software applications within your organization seamlessly. It ensures a smooth flow of information and processes.

Remember, the integration approach you choose should align with your organization’s needs and the systems you’re working with.

To achieve the best results and make the most of these types, you need to familiarize yourself with the concepts that are involved in the application integration process.

Check out the next section, where we have curated a list of must-know concepts for successful app integration.

Must-Know Concepts of Application Integration

Now, in an effort to better understand the application integration concept, let’s look at some key aspects of the same.

These are highly crucial for an individual to understand, as they help in the better execution of application integration on any platform.

These concepts are generally mastered by the Application integration experts that you hire; however, you still must have a basic knowledge of the concepts to get the ball rolling

Here are the concepts that we are talking about –

♦ Data Mapping

When you’re integrating applications, data mapping helps you define how data from one system corresponds to data in another.

This mapping allows the data to be more accurately presented as per the requirement, across the application, for a better understanding of the user.

♦ API (Application Programming Interface)

APIs act as bridges between different applications, allowing them to communicate and share data.

It is one of the most commonly used methods to integrate applications and allows the base app to fetch data from different sources in real-time.

♦ Event-Driven Architecture

In an event-driven architecture, actions or events in one application trigger responses in others.

If an application requires automated control, event-driven architecture is the best way to move forward.

♦ Batch Processing

Batch processing involves collecting and processing data in groups or batches rather than in real time.

This approach is useful for scenarios where immediate data exchange isn’t necessary, such as overnight data updates.

With all those concerts, you might have gotten a solid understanding of application integration.

One of the key problems that many individuals face is that they are unable to distinguish between app integration and data integration.

These concepts will help you understand the differences between the two.

If you still have your doubts about the same, here’s a quick comparison between the two that will help you understand the key differences between them.
