WebPerformance of dynamic hashing will be good when there is a frequent addition and deletion of data. But if the database is very huge, maintenance will be costlier. Static hashing will be good for smaller databases where record size id previously known. If there is a growth in data, it results in serious problems like bucket overflow. WebNov 10, 2024 · Dynamic Hashing. Static Hashing. In this type of hashing, the address of the resultant data bucket always will be the same. Let's take an example; if we want to generate the address for Product_ID = 76 using the mod (5) hash function, it always provides the result in the same bucket address as 3. In memory, the number of data …
