Difference between ADO and Technology

Difference between ADO and
1. ADO used connected data usage, while used disconnected data environment.
2. ADO used OLE DB to access data and is COM-based, while uses XML as the format for transmitting data to and from your database and web application.
3. In ADO, Record set, is like a single table or query result, while in Dataset, can contain multiple tables from any data source.
4. In ADO, it is sometime problematic because firewall prohibits many types of request, while in there is no such problem because XML is completely firewall-proof.

Difference between Dataset and ADO Recordset
1 A DataSet can represent an entire relational database in memory, complete with tables, relations, and views.
2 A DataSet is designed to work without any continuing connection to the original data source.
3 Data in a DataSet is bulk-loaded, rather than being loaded on demand.
There's no concept of cursor types in a DataSet.
4 DataSets have no current record pointer You can use For Each loops to move through the data.
5 You can store many edits in a DataSet, and write them to the original data source in a single operation.
6 Though the DataSet is universal, other objects in ADO.NET come in different versions for different data sources.
