Data readers are considered forward-only. What does this mean in the context of ADO.NET?
- They can move both forward and backward through the data.
- They can only access the data in a random order.
- They can only move forward through the data once and cannot move backward.
- They can only read data from the database but cannot update it.
In ADO.NET, a forward-only data reader allows sequential access to the data. Once a record is read, it cannot be revisited, making it efficient for read-only scenarios with large datasets.
