Geospatial data is vast and often resides in databases or data warehouses. Data stored in a filesystem is only accessible through your local computer and is limited to the speed and efficiency of your work space. Collecting and analyzing geographic information within storage systems of relationally structured data increases efficiency.
Spatial databases are optimized for storing and retrieving your data. Data stored in databases are accessed through client software. The client is a computer or hostname (where the database is located).
