Normalization is the process of organizing a database to reduce redundancy and improve data integrity. It involves dividing large tables into smaller, related tables and defining relationships between them. This reduces data duplication and ensures that data is stored efficiently, making updates and deletions easier and more reliable. a) Data Warehousing involves collecting and managing large amounts of data but does not specifically target redundancy. b) Data Mining involves analyzing large datasets to discover patterns and trends, not reducing redundancy. d) Indexing improves the speed of data retrieval but does not address redundancy. e) Partitioning involves dividing a database into smaller segments for easier management but does not eliminate redundancy.
The speed of a boat in still water is 35 km/hr. If the boat covers 150 km in upstream in 5 hours, then find the time taken by the boat to travel 200 km ...
A boat can cover 60 km in still water and 75 km in downstream in 4 hours and 3 hours respectively. Find the time taken by the boat to cover 60 km upstre...
Speed of boat is 10 km/hr. Speed of the stream is 30% less than speed of boat. Then find time taken by boat to go 34 km downstream?
