Thanks for all your responses. Has any of you ever accessed the database at home? If yes, is it fast or slow? I just think it would be faster with a laptop than with a hard drive. I think even if you connect the external hard drive to a PC, the PC may not able to read the data.
I thought of this topic because if you get an urgent call from hospital or patient and you need to look up something in A.C. from home. Methods like remote access (logmein, etc.) are not as fast.
I understand if you modify data from home (put in a new note,etc.) this new information might not go into the server if you do not synchronize it, so writing new note at home might not be a good idea. Anyway, able to access all data from home or anywhere with your laptop, if necessary, without having to connect a cable or going on line would be great.
I guess the answer to my question is yes, you can use a laptop as an backup device or a hard drive but I still have the question if you can easily access Amazing Charts database

Thanks
