Application of embedded database SQLite in nuclear instrument data management

On the issues of complex operation, different format, large difficulty to upgrade, and others when using the document for nuclear instruments to manage binary data blocks, the paper embeds SQLite database which is small, fast, robustness, stores binary spectral data block in BLOB data type, s bulk data through transaction, and improves the spectral data management performance and security. According to spectral data management requirements, designing a practical data management system to verify the SQLite database data management is high-efficiency, convenient, reliable, and other advantages in the nuclear instruments.
