Data Compatibility Issues

External databases have complex relationships that must be maintained in the GIS interface.

Connection between external databases and spatial data must be seamless to the end user.

Data Compatibility Issues

External database updates must be displayed real-time in the GIS interface.

Should be able to work with the external databases in GIS interface or in the native application, e.g. Microsoft Access.
