Table 2 System Features 
To make localized utilization aimed at facility management possible, large-scale data (scaled at 1/300 to 
1/1,000) is stored. As a result, data from drawing of different scales to best suit the relevant purposes 
can be stored. In this manner, structuring the data base with internally unified coordinate systems, will 
make the system capable of mutually exchanging data. Small-scale data bases are provided with 
individual calculation functions, and if small-scale data bases can perform index functions for large-scale 
data bases.
