RE: Architecture Question

Hi Randy,

It is common to use SQL CE to hold the data so that the application is still
usable in case there are connection problems to the server. It provides an
offline solution which is ideal for most business applications.
Typically, you would use your web service to refresh or obtain updates to
your data, or send new data back to the server, but essenitally all the info
that the user needs to see should be stored on your SQL CE database.
