Objective To improve the efficiency, security, and confidentiality level in the management of medical experiment documents and original data, especially the management of large ifles.Methods By following the standardized database design method in the Structured Query Language (SQL) Server 2008 database platform, a medical laboratory document management system was developed with Java programming language, which was object-oriented and could utilize the cross platform.Results The use of the database management system could realize functions such as data uploading and downloading, authority management, automatic backup, andetc.Conclusion The method adopted in this research was to save the original data and document in the experimental process to the database in binary, which effectively ensured the efifciency and conifdentiality in the management of medical experiment data and document.%目的：提高对医学实验文档、原始数据尤其是大文件的管理效率，增强安全性和保密性。方法在数据库管理软件（SQL server 2008）平台下遵循数据库规范化设计方法，利用跨平台的面向对象的程序设计语言（Java）开发医学实验文档管理系统数据库。结果利用该系统实现了对医学实验文档及原始数据进行上传、下载及权限管理和自动备份等管理功能。结论本研究所采用的方法是将实验研究过程中的原始数据和文件直接以二进制的形式保存到数据库，有效地保证了数据的安全性和保密性。
