Disadvantages of Static Hashing

Disadvantages of using static hashing techniques in DBMS are:

  • Static hashing is not a good choice for big data.
  • This process takes longer than usual because the hash function has to go through all memory locations in the DBMS system.
  • Does not work with extensible databases.
  • The sorting technique is not good compared to other hashing techniques.

Static Hashing in DBMS

Static hashing refers to a hashing technique that allows the user to search over a pre-processed dictionary (all elements present in the dictionary are final and unmodified). In this article, we will take an in-depth look at static hashing in a DBMS.

What is Static Hashing?

When a search key is specified in a static hash, the hashing algorithm always returns the same address. For example, if you take the mod-4 hash function, only 5 values ​​will be produced. For this to work, the output address must always be the same. The number of buckets at any given time is constant....

Conclusion

Static hashing is one of many other hashing techniques used to show that data is not stored sequentially and also provides the correct memory address for each value in the data. Unlike other hashes, static hash methods can be used for static results without changing the values ​​of objects, objects, and relational data in the DBMS....
