<u><em>Differences between barcode reader and character recognition devices:</em></u>
Barcode Reader or Barcode Scanner:
- Barcode Scanner scans the data by brightening the barcodes usingSensor
- The analog signal is then converted into digital signal by Converter.
- The Decoder calculates the converted data and sends valid data to the computer.
Character Recognition Devices (OCR):
- OCR scans the physical document and converts them into two-coloured format.
- The darker and lighter area are identified as characters and blanks respectively.
- The common methods used are: Pattern Recognition and Feature Detection.
Answer:
Explanation:
Transitive dependency
In this case, we have three fields, where field 2 depends on field 1, and field three depends on field 2.
For example:
Date of birth --> age --> vote
Partial dependency
It is a partial functional dependency if the removal of any attribute Y from X, and the dependency always is valid
For example:
Course and student these tables have a partial dependency, but if we have the field registration date, this date will depend on the course and student completely, we must create another table with the field registration date to remove this complete dependency.
If we remove or update the table registration date, neither course nor student must not change.
