[postgis-users] I need geo-database ?

[orkun]

hello

I am new to postgis and geo-database.

I want to know what db table containing geographic columns is more 
beneficial
than conventional db table.

For example as far as I know,
In ESRI's shape file has a shape column. But it is closed to see the 
geometric shape with coordinates.  And one can not query on real 
coordinates on  table.

Can you tell me more about the comparision of geo-table with 
conventiaonal table ?
so I could say that I need geo-database  and  conventianal  table (and  
ESRI' shape file)
are not enough to carry out certain works.

What does geo-table provide more than conventional-table does ?

kind regards

regards

Ahmet Temiz
