Jon Hyokchol, Weian Wang · Cehui kexue · 2012
In this paper,it proposed the theory on the temporal-spatial database construction for public building real estate management on the basis of Base State with Amendments.Firstly,it briefly introduced the situation of public building real estate management in D.P.R.Korea.Next,it analyzed the properties of temporal-spatial data for public building real estate management,and for minimizing data redundancy and maximizing the efficiency of management system,defined the time fields in the spatial and attribute data structure.Then the data were divided into not changeable and more frequently changeable data.It also designed the whole temporal-spatial database model for public building real estate management on the basis of this theory,and constructed database of A region.
