Enterprise Application Integration

Enterprise Application Integration (EAI) refers to the process of integrating the collection of all technologies and services in an enterprise into a software and hardware system. EAI is an integration framework composed of middleware technologies that promote communication between various enterprise applications, such as Enterprise resource planning (ERP), supply chain management, business intelligence applications and Customer-relationship management (CRM) applications. 

Research firm Gartner defines EAI as “unrestricted sharing of data and business processes among any connected application or data sources in the enterprise.”

Points to Remember

  • EAI links key applications within an organisation, making it easier to automate business processes to a greater degree while making sure not to make any significant changes to data structures and applications.
  • Applications are typically linked either at the front-end (GUI) or at the back-end with the help of various APIs (Application Programming Interface).
  • EAI usually faces challenges like programming languages, operating systems, database architecture and other challenges posed due to lack of support for legacy systems.
