Difference between Dataset and DataReader : Points to be consider while choosing between the DataSet and DataReader objects
DataSet object | DataReader object |
Read/Write access | Read-only access |
Supports multiple tables from different databases | Supports a single table based on a single SQL query of one database |
Disconnected mode | Connected mode |
Bind to multiple controls | Bind to a single control |
Forward and backward scanning of data | Forward-only scanning of data |
Slower access to data | Faster access to data |
Greater overhead to enable additional features | Lightweight object with very little overhead |
Supported by Visual Studio .NET tools | Must be manually coded |
