What is difference between Connected and Disconnected Environment

Connected Environment :
  • Connected Environment needs a constantly connection of user to data source while performing any operation.
  • Only one operation can be performed at a time in connection Environment.
  • DataReader is used in Connection Environment.
  • It is slower in speed.
  • We get updated data in it.
Disconnected Environment :
  • Disconnected Environment doesn't need any connection.
  • Multiple operations can be performed.
  • DataSet is used in it.
  • Disconnected Environment has a good speed.
  • There is a problem of dirty read.
