Correct answer: D
A distributed database is a database in which data is stored across multiple physical locations, connected via a network. It maintains a single logical view of the data, even though it is physically spread across different sites. This allows for improved performance, fault tolerance, and scalability. The data is managed by a distributed database management system (DDBMS) that ensures consistency and coordination across all nodes.
हिन्दी उत्तर:
वितरित डेटाबेस एक ऐसा डेटाबेस है जिसमें डेटा एक से अधिक भौतिक स्थानों पर नेटवर्क द्वारा जुड़े हुए स्थानों पर संग्रहीत होता है। यह डेटा का एक एकल तार्किक दृश्य बनाए रखता है, भले ही यह विभिन्न स्थानों पर भौतिक रूप से फैला हो। इससे प्रदर्शन, त्रुटि प्रतिरोध और स्केलेबिलिटी में सुधार होता है। डेटा का प्रबंधन एक वितरित डेटाबेस प्रबंधन प्रणाली (DDBMS) द्वारा किया जाता है जो सभी नोड्स पर सुसंगतता और समन्वय सुनिश्चित करती है।
