वितरित डेटाबेस एक ऐसा डेटाबेस है जिसमें डेटा एक ही कंप्यूटर या सर्वर पर संग्रहित न होकर नेटवर्क से जुड़े दो या दो से अधिक कंप्यूटरों या भौगोलिक रूप से अलग-अलग स्थानों पर स्थित डेटाबेस प्रणालियों में वितरित रहता है। इन सभी स्थानों पर रखे गए डेटा को उपयोगकर्ता के लिए एक ही तार्किक डेटाबेस के रूप में प्रस्तुत किया जाता है। दूसरे शब्दों में, वितरित डेटाबेस में डेटा का भौतिक स्थान अलग-अलग हो सकता है, लेकिन उपयोगकर्ता को ऐसा अनुभव होता है जैसे वह एक ही डेटाबेस के साथ कार्य कर रहा है। सूचना एवं संचार प्रौद्योगिकी के विकास के साथ वितरित डेटाबेस का महत्व बढ़ा है, क्योंकि विभिन्न संस्थानों, पुस्तकालयों, विश्वविद्यालयों, बैंकों और व्यावसायिक संगठनों में बड़ी मात्रा में डेटा को अलग-अलग स्थानों पर संग्रहित और साझा करने की आवश्यकता होती है। वितरित डेटाबेस प्रणाली में कई डेटाबेस साइट या नोड होते हैं। प्रत्येक साइट किसी स्थानीय कंप्यूटर, सर्वर या नेटवर्क से जुड़ी डेटाबेस प्रणाली हो सकती है। ये सभी साइट संचार नेटवर्क के माध्यम से एक-दूसरे से जुड़ी रहती हैं। किसी संगठन के अलग-अलग विभागों या शाखाओं में स्थानीय डेटाबेस हो सकते हैं और आवश्यकता पड़ने पर वे एक-दूसरे से डेटा का आदान-प्रदान करते हैं। उदाहरण के लिए, किसी विश्वविद्यालय की दिल्ली, पटना और मुंबई स्थित शाखाओं में अलग-अलग डेटाबेस हो सकते हैं। प्रत्येक शाखा अपने स्थानीय छात्रों और कर्मचारियों का डेटा रख सकती है, जबकि अधिकृत उपयोगकर्ता पूरे संगठन से संबंधित जानकारी तक नेटवर्क के माध्यम से पहुँच सकता है। वितरित डेटाबेस की संरचना को समझने के लिए
