It is often difficult to quickly and efficiently search by using simple data management software, such as excel. In order to solve the problem, our team used Python development tool to build high-performance retrieval software, which enabled the equipment custodian to maintain or redesign the database according to actual needs. Through actual verification, this system not only can greatly improve the accuracy of device access, but also has good expansion portability, which could manage various multimedia data systems.展开更多

With the rapid development of the Internet, the seriousness of this problemis becoming increasingly prominent. Based on the information construction of university archives management as the center to carry outresearch, improve the service level of university archives from the first two aspects discusses the necessity of the information constructionof the archives management, promoting the development of colleges and universities. Secondly introduces specific measures of realizing theinformatization construction of university archives management and archives management standardization, digitization, archives informationnetwork construction, the archives management personnel to conduct a comprehensive training. The fixed assets of university is an important partof the state-owned assets, and its asset management level is directly related to the safety of state-owned assets, the use efficiency of assets and thepromotion of the teaching and research level in universities. The university fixed assets data information management is an important aspect ofasset management, it provides decision-making basis for the management of fixed assets in colleges and universities, affecting the efficiency ofthe entire asset management.展开更多
