The Research And Implementation Of EAM For Coal Industry Based On J2EE

Firstly, this paper analyzes the EAM's theories and confirms the technological course of the system, according to characters of coal enterprises, such as separate geographical locations, collective management, business implexity. Secondly ,based on investigating and analyzing, presents the blue print of coal industry informatization and that cost advantage is means of the enterprise competitive tactic. Thirdly ,with case tool, such as Rational Rose, performs requirement modeling, analyse modeling, data modeling, code framework creating and particular design on EAM. Then according to characters of coal industry, this paper brings out EAM system architecture based on the combination of J2EE and MVC design pattern, which endows the whole system with flexibility, reusability, testability and extensibility. Lastly realizes the EAM with IBMWSDA5.11 (WebSphere Studio Application Developer).The application effect of EAM has proved that functions and technological route of EAM are feasible and applicable. The models brought out in this paper have high universality in coal enterprises, such as material plan model, monopoly for purchase of material model, asset alteration model, equipment maintain model, equipment interior lease model, which establish foundation stone to improve the reusability of the software and are very worth of popularizing in coal enterprises.
