Dataset in ado
The ADO.NET
DataSet contains DataTableCollection and their DataRelationCollection . It
represents a collection of data retrieved from the Data Source. We can use
Dataset in combination with DataAdapter
class. The DataSet object offers a disconnected data source architecture. The
Dataset can work with the data it contain, without knowing the source of the
data coming from. That is , the Dataset can work with a disconnected mode from
its Data Source . It gives a better advantage over DataReader
, because the DataReader is working only with the connection oriented Data
Sources.
The Dataset contains the copy of the
data we requested. The Dataset contains more than one Table at a time. We can
set up Data Relations
between these tables within the DataSet. The data set may comprise data for one
or more members, corresponding to the number of rows.
The DataAdapter object allows us to
populate DataTables in a DataSet. We can use Fill method of the DataAdapter for
populating data in a Dataset. The DataSet can be filled either from a data
source or dynamically. A DataSet can be saved to an XML file and then loaded
back into memory very easily. The following links shows more information of
Dataset in details.
