What is ArcSDE Esri?
1Introducing ArcSDE ESRI®ArcSDE is the geographic information system (GIS) gateway to relational databases. It allows you to choose the relational database management system (DBMS) you want to use in your organization to fully integrate GIS and DBMS. This book provides an overview of what ArcSDE is and how it works.
What is ArcSDE Spatial indexing?
ArcSDE builds a spatial index by applying a grid to the feature class. It records features that fall within each grid cell in an index table (the S table of the feature class schema). A feature that falls in more than one cell is listed in each. Grid cells with no data are not included in the table.
How does ArcSDE store geometric shapes?
Basic feature storage ArcSDE stores geometric shapes as x,y coordinates and true curves. Points are recorded as a single x,y coordinate, lines as a series of ordered x,y coordinates and curves, and areas as sets of lines composed of x,y coordinates and curves that have the same starting and ending point.
