Using spatial feature to improve the performance of your Google map applications

Hi Guys ,

There are many ways to improve the performance of Google map application. Some of them are
1. Display only visual overlays
2.Marker clustering and polygon and polyline simplication
3.Use tile server
4.caching
5.Use Spatial features of your database
6. ....

Here i am going discussing about how to use spatial features of your database to improve the performance
1. Store Marker's location of lat,lng as native Point type
2. Store Polyline's   lat,lng as native LineString type
3. Store Polygon's region as native native Polygon type.
