Datacommand objects?

[Guest]

I am new to VB/.NET
What are datacommand objects? Can I use them instead of Dataset to access
database and make changes to database?

Thanks.

There are lots and lots to say either on dataset or Datacommands . the
least to say
A data command is just a reference to a command to execute on some database
while you can think of dataset as IN MEMORY representation of the
database . you use dataset to like take a copy of all . or part of the
database into memory . do changes on that copy ( with no need to be
connected to the database ) . once you did all this changes . you can go
back open the connection and update these changes to the database.
