== Concept ==
In actual case, the blockchain essentially has no querying abilities when compared to [[database|traditional database]] and with a doubling of [[Node (networking)|nodes]], network traffic quadruples with no improvement in throughput, latency, or capacity.<ref name=":2">{{cite book|last1=Raikwar|first1=Mayank|last2=Gligoroski|first2=Danilo|last3=Velinov|first3=Goran|date=2020-03-12|title=2020 Seventh International Conference on Software Defined Systems (SDS)|chapter=Trends in Development of Databases and Blockchain|pages=177–182|doi=10.1109/SDS49854.2020.9143893|arxiv=2003.05687|isbn=978-1-7281-7219-4|s2cid=212675742 }}</ref> To overcome these shortcomings, taking a [[database|traditional database]] and adding blockchain features to it sounds more feasible.<ref>{{Cite web |last=Anadiotis |first=George |title=How to use blockchain to build a database solution |url=https://www.zdnet.com/article/blockchains-in-the-database-world-what-for-and-how/ |access-date=2020-03-27 |website=[[ZDNet]] |language=en}}</ref> That's how the concept of blockchain-based database came into existence, which consists of multiple member clouds riding on two primary layers; the first one is ''Database Interface'' and the second one is the ''Blockchain Anchoring''.<ref name=":0" /> The idea behind the blockchain based database concept is to complement the functionality and features of [[Relational database|SQL]] and [[NoSQL]] databases with blockchain properties: data immutability, integrity assurance, decentralized control, [[Byzantine fault|Byzantine fault tolerance]] and transaction traceability.<ref>{{Cite book |chapter-url=https://www.researchgate.net/publication/318131748
== Implementations ==
[[Oracle DBMS]] implements support for a blockchain-based database model.<ref>{{Cite web|url=https://docs.oracle.com/en/database/oracle/oracle-database/23/nfcoa/blockchain.html|title=Blockchain|language=en-us |website=Oracle Help Center |access-date=2024-11-07}}</ref>
