A typed dataset uses .xsd file i.e. the XML file to get information about the tables & columns. So we can use the table names & column names directly. We can derive a new dataset from a typed dataset.

In a general dataset, the tables & columns are exposed as collections & we have to make use of them.

e.g. consider a dataset 'ds' having a table 'emp' with a column 'eid' & we want to retrive the 1st record.

in typed dataset:- ds.emp(0).eid

in dataset:- ds.tables("emp")(0).columns("eid")
