Multi-source heterogeneous data storage methods for omnimedia data space

This article mainly introduces the design of a multi-source heterogeneous data set fusion system and discusses the key technologies and requirements of the system. Its application fields are discussed in detail, and the system functions and performance are briefly described. Finally, a multi-source heterogeneous data storage and retrieval system for omnimedia space is designed, effectively improving the information acquisition ability and query speed. Comparing traditional storage methods with multi-source heterogeneous storage methods, the results showed that both storage modes could better meet practical work needs. However, query results retrieval based on multisource heterogeneous storage methods was faster and had fewer security risks. In addition, the recall rate of data information has increased by about 4.78%, and the precision rate has also increased by about 7.45%. Storage technology based on multiple sources and heterogeneity is conducive to improving user experience and satisfaction, and providing more complete services for enterprises.
