| Abstract: | Based on the analysis of railway information sharing platform construction,it was pointed out that the establishment of a shared database was the core of the integration of existing information resources,and one of the key factors in the implementation of railway information.It was proposed a data source layer contains,shared database layer and the theme of the three-layer architecture of the shared database design.By studying the data federation mechanism,ETL data integration mechanisms and middleware-base... |
