MMS-IU model for incremental update of spatial database

Abstract

The update quality of spatial database determines the data's value. Combined with the characteristics of the spatial database updating, we studied incremental updates modeling of the spatial database and supported a multimode update model, which referred to as the MMS-IU. The model has two features: (1) it contains two different update ways to enhance the applicability of the model; (2) we combine time and events with the version management mechanism, which let the model becomes an event-based and object-oriented update model. The article elaborated the basic principle of an updated way supported by the MMS-IU model - that is based-edit update way. Aimed at the obtainment for changes information, incremental information fusion, concurrency control such key issues which existed in updating process, we proposed a reasonable solution. © Springer-Verlag Berlin Heidelberg 2013.
