| Abstract: | Marine geology data produced by multiple channels are usually distributed, multi-sourced and heterogeneous. In the process of constructing a realistic marine geological database system, we noticed the characteristics of marine geological data, and then proposed a heterogeneous data integration mode based on a unified data model and the way of data and application service based on WCF. The unified logical data model is mainly made with reference to the POSC model which was generally used in the field of oil and gas. In the WCF service architecture, data and applications are packaged into class objects and transfered by object serialization and deserialization. This form of system design has the advantages of on unchanged storage and management mode of original data. |
