Chained Progrssive Overflow Pointer from home location to 1st location found in probe. When that is full point to next location found in probe. Chaining With Separate Overflow Area Put all collisions in a separate area. Synonyms are linked together to speed searching. If a location can hold more than one record it is called a bucket .
Lets take a previous example.
We can calculate the number of locations having x records assigned for various values of x. Even with a much greater packing density we can avoid collisions. With a smaller bucket size we might start getting some expected collisions. Good for a secondary index or for a situation where the data itself cannot be rearranged.
