The laboratory produces a large amount of data and information every day. Relatively speaking, manual management has low efficiency and high error rate, which is not conducive to the rapid scientific analysis of data, nor to the traceability and management of data. Lims, a laboratory management system, can realize data management in the whole process of laboratory record integrity verification, master data evaluation, data traceability management, electronic signature and data storage. Lims, the laboratory management system of Qingzhi, records the original information of each analysis data, including every step of data generation, modification and audit. When in doubt about the data, you can call up the original records corresponding to the data at any time. Compared with the traditional paper storage data, the electronic experimental data makes the data more secure and reliable. Strict verification system makes any data modification recorded. Distributed data storage prevents data from being destroyed catastrophically.
