Data Access Layer Development for Interoperable GIS Solutions Using NHibernate Mapper

This paper presents the NHibernate Mapper, an object-to-relation database mapping tool that has the ability to automatically cross the schema and database library to provide suggestions on the correspondence and match the database provided by this NHibernate Object Mapper framework. Suggested mapping can be accepted or rejected via the GUI, which can also define the mapping in a final form by hand. Because of their ability to support data access layer development through database schema analysis for DBM enabled, NHibernate can provide great support to GIS solutions. NHibernate mapper has the possibility, in particular with the Domain Class library generated by GIS solution to allow rapid data access laying development.
