Comparison between file Geodatabase and personal Geodatabase

Comparison File GeodatabaseAnd personal Geodatabase

Overall trend ArcGIS 9.2 of the file GDB is to gradually replace personal GDB.
In itself, personal GDB has some limitations. Microsoft Access is irrelevant.
Therefore, I have also speculated that the introduction of file Geodatabase can gradually get rid of access restrictions without being subject to Microsoft's Technology .

Now let's compare the two functions (same and different)
1. All functions provided by the desktop are free of charge.
2. creation methods are all created through arccatalog
