Method for construction of business- oriented marine geology data service platform

With the deepening of the marine geological survey,marine geological data have been increasingly accumulated,but the marine geological data service system can not meet the application requirements. Through analyzing the status of the application of existing marine geological data,the authors presented Three- layerarchitecture of the marine geological data service platform design approach,designed the unified logical model based on business using object- oriented thought,implemented marine geological data services platform using WCF and NHibernate technologies,realized integrated access to heterogeneously distributed marine geology database,and achieved data query based on business models. Compared with the operation of the traditional method for data query,users can simply choose business needs,and obtain the data after setting up constraints,thus greatly facilitating the user's application demand for marine geological data.
