The invention provides an enterprise-level full-amount data intelligent search implementation method and system. The system comprises an access layer, a model layer, an algorithm layer, a component layer, a service layer and a display layer, and the design of the system follows four unified principles, namely, a unified leader, a unified plan, a unified standard and a unified construction principle. Exemplary application construction should fully consider safety protection, fault-tolerant capability and anti-interference capability of the system, ensure long-term stable, safe, reliable and efficient operation of the system, have good compatibility and expansibility, abide by the design concept of taking customers as the center, provide consistent and user-friendly experience, meet the actual needs of services to the maximum extent, and the operation is convenient, the functions are complete and the interface is friendly; the application design adopts an international advanced technicalroute. Old and heterogeneous compatible technologies are fully utilized, and previous IT investment of state grid companies is protected. The system and the method meet the international and nationaluniversal standard and support various hardware platforms are supported.
