| There are many application system applying to Guizhou electric power system, forexample, EMS, TMR, WDS, OA, MIS, 95598 call center, etc. The appropriativeinterface program is needed for data exchanging between two system, because they areindependent each other. A majority of application system that was used for different speciality didn't shareand exchange data each other. Software, hardware and protocol of these systems werenot the same as each other, and they had notable distribution and different construction.The function and data of these systems were redundant, and the same data had deferentmeaning. This information island made it difficult to share data. This paper expatiates the concept of EAI(Enterprise Application Integration). Theworkflow, application software, hardware and standard are joined up by EAI. Thesupplication systems deal with workflow and data like a system, and the efficiency ofEnterprise was improved. Secondly, this paper introduces the aspect of XML. XML defines a type of dataconstruction by an opening description method itself, and expresses the connectionamong data. These data organized in the construction are friendly and handling forapplication program. One of the advantages is that it permits every one to establish tagsfitting him, and these tags can be put into use rapidly. The paper introduces a method for the question of Guizhou electric power systemthat is used to integrate different construction data by EII and XML. A new diagram isprovided to meet demand of real data. The data, that are extracted, Transformed, Loadedby ETL, are standardized to support BI. |
