What is Application Integration?

Application integration is the process of enabling independently designed applications to work together seamlessly. It involves connecting different software systems, applications, or services to share data, workflows, and functionalities. The application integration definition encompasses the use of tools and technologies to bridge gaps between disparate systems, ensuring they operate as a unified ecosystem. By leveraging an application integration framework or application integration platform, businesses can streamline operations, improve communication, and enhance productivity.

Application Integration Examples

Examples of application integration solutions include:

Integrating a CRM system like Salesforce with an ERP system such as SAP to synchronize customer and financial data.
Linking e-commerce platforms (e.g., Shopify) with inventory management systems for real-time stock updates.
Connecting marketing tools like Mailchimp with analytics platforms like Google Analytics for campaign performance tracking.

Application Integration Technologies

Application integration technologies include APIs (Application Programming Interfaces), middleware, enterprise service buses (ESBs), and cloud-based integration tools. These technologies form the backbone of enterprise application integration, enabling seamless communication between on-premises and cloud-based systems.

Application Integration vs Data Integration

While application integration focuses on connecting applications to share processes and workflows, data integration emphasizes combining data from multiple sources into a unified view. Application integration vs data integration comparison suggests that the former deals with operational efficiency while the latter addresses data consistency.
