Enterprise architecture, referred to as EA. It refers to a universal solution provided for systematic and universal problems in enterprise information management systems. More specifically, it is based on a business oriented and driven architecture to understand, analyze, design, build, integrate, expand, operate, and manage information systems. The key to complex system integration is architecture (or system) based integration, rather than component (or component) based integration.

Effective enterprise architecture plays a decisive role in the survival and success of enterprises, and is an indispensable means for enterprises to gain competitive advantage through IT.
