Design And Implementation Of Military Secret File Data Management System Based On WPF+SQL

With the rapid development of the information age,the information,automation and intellectualization of large-scale data management ideas have penetrated into all fields.Comparing with the traditional manual management methods,it can standardize the data management process scientifically and improve the management efficiency.It can also ensure the safety of data to a greater extent.However,the current grass-roots units often rely on the traditional management mode in the management of confidential documents and materials,there are many problems,such as low degree of informatization,non-standard management system,slow retrieval speed and so on.Not only the management efficiency is low,but also easy to cause damage and loss of documents and materials,and even bring about serious leakage.Hidden danger.In view of the above problems,the design and development of a file and data management system based on information management,convenient and easy to use,strong security and practical army,for improving the current grass-roots unit file and data management level has a strong practical significance.Therefore,this paper focuses on the design mode of WPF under Windows operating platform,and focuses on the key technologies such as C_# programming language,SQL database management,QR two-dimensional code,face recognition,etc.By using WPF to make application program front-end,combining with SQL Server database,a set of ciphertext is designed and developed for grass-roots units.The document data management system mainly realizes the functions of storing and registering secret documents and materials,digital management and monitoring,data inquiry and borrowing,data analysis and statistics,etc.It has the characteristics of convenient management,rapid retrieval,strong reliability and good confidentiality.Based on this,this paper mainly carries out the following work: Firstly,aiming at the new WPF application presentation layer design pattern,starting from its architecture,we constantly explore the WPF development concept based on "data-driven",and then deeply understand its XAML markup language,Data Banding,Dependency Property.The deep logic of the key technologies such as Routed Event,Template,etc.can make the program design more concise and clear,the human-computer interaction more reasonable and easy to use,the data management more unified and standardized,and ensure the overall stability of the system.At the same time,according to the functional requirements of the system,the SQL database,two-dimensional code,face recognition and other related technologies are studied to understand its internal implementation mechanism,through the introduction of ZXing.NET,Emgu.CV and other third-party libraries to achieve good coupling of related functions.Then,through the analysis of the current situation of secret documents management in the army,the overall framework of the system,database structure and basic functions of the system are planned and designed;according to the WPF design pattern,the interactive interface is designed and laid out;in the realization of the functions of each module,the concept of "data-driven" is emphasized.Simplify code logic and improve data processing efficiency.Finally,by building a client-server development / test environment,the system function modules are tested to ensure the stable operation of the system.
