DataAdapter acts like a mediator between Dataset and
Datastore(ie.Oracle,Sqlserver or Access).It has two methods
fill() and update().
For Ex:
SqlConnection con=new SqlConnection
("DataSource="databaseEngineName";Initial
Catalog="DataBaseName";User
Id="userName";Password="password";);
DataAdapter da=new DataAdapter(sqlcommand,con);
DataSet ds=new DataSet();
da.fill(ds,"tablename");
da.update(ds);
