The database in the system consists of two types, tabular data and spatial data.
The tabular data is stored in SQL format and the spatial data is stored in Geodatabase format. The structure of the geodatabase is optimized for both performance
and storage for multi levels of GIS data layers as shown in Fig. 10. The SLRS
database model is structured to be stored physically in different format although the
relationships between the two categories of data are preserved regardless of whether
the division is physical or logical (in a hybrid database model). This means that two
separate databases were used in the system, one for spatial data and one for attribute
data.
