Spatial Database Modeling Analysis Based On Tourism Geological Resources

This dissertation puts forward purpose and meanings of the spacial database research first, which fix attention on various spacial applications, such as the medicine, weather, tour planning. At combine present contentses of domestic and international research on, emphasize to modeling the spacial database and analysis, its angle of view looks after both sides the advantage of the object and the field, the grid space and the vector data structure.Then make use of the space resemble the shape language righteousness to the entity- relate to the model to carry on expand, with the expression spacial entity object and contact, and combine the abstract data type within the object technique, expanding the SQL customer from the definition data type with handle the space structure.The next in order, thesis above-mentioned set up the medel analysis method to apply to the tour geology resources to practice medium, to apply the realm to carry on abstract, withdraw the space several main factor, become the concept model. Make use of the Rational Rose is of usage is chasing toward born machine of the engineering tool- mode the logic model that the tour geology view concept model conversion is an 0racle8.End in article, the synopsis ground introduced the space data excavation technique, among them academic follow before it an of the space timespace stand alone ordered the analysis and can used for the transportation discharge the early warning is medium. Along with the 3Ss technical and extensive applied, establishment at the space database on of open the position service and will go deep into square aspect noodles of the society.
