How can I add multiple tables to dataset with Fill using IDataAdapter?

Refering to How can I read multiple tables into a dataset? My App has a db factory. Can i use 'da.Fill(ds)' [with IDataAdapter implementation] for multiple tables开发者_运维问答? Or how can i add more tables to the same DataSet. Copy the whole table would work but is this the only way?
