Development Of Archive Management System Integration Service For Students

The subject of Develop of archive management system integration service forstudent comes from Network Center of China University of Geosciences(Beijing). Itis a part of the second phase of construction of digital campus with upgrading some ofthe features of the original system reform.The system is based on an annual basis to establish an archive database, That isthe definition of the contents of a database table. Function of the system are migratingdata from official database to archived database and querying archived data. This way,you can greatly reduce the load pressure of official databases, other systems on theofficial database access efficiency has improved significantly, to ensure thecompleteness of the archive data permanently stored."How to reate a filing system" and "How to implement archiving data query", thesubject around these two issues, from requirements analysis to system implementationlevel, provides in-depth research and a good solution. Main research content of howto create a archiving system are establishing reasonable configuration and migratingsmoothly the archived data from the official database to archive database. Mainresearch content of how to implement archiving data query are multiple data sourceswitching and simple query mechanism.The whole system is divided into the Web server-side development and databaseserver-side development. Web server-side development is designed using MVCframework model and developed using a combination of Struts2, Hibernate andSpring. Struts2is responsible for the control of the business logic jump, Hibernate isresponsible for access to the database, Spring is responsible for the inversion ofcontrol, transaction management and the slice programming. Presentation layermainly uses jsp page embedded in Struts2tags. Presentation layer provides a simpleand easy-to-view interface to users. Development of the database server uses the PL/ SQL programming language, mainly to complete the database migration from onedatabase to another.The system meets the China University of Geosciences (Beijing) Network Centerneeds, providing a complete solution for archiving data migration and query.Archiving data migration program is running in a safe and stable database serverenvironment with high efficiency. Simply calling in Web server eliminates theintermediate container and there is no transfer of archived data between the Webserver and the database server. Hibernate framework is responsible for archiving dataquery. It is based on object-oriented thinking to achieve query archived data.Developers only need to write simple HQL statement, Hibernate automaticallyconverts it to a higher efficiency of the SQL statement. Switching between multipledata sources is using the slice oriented programming ideas. The only thing you needto do is configuring multiple data sources without writing the same code in theswitching data code. During the program is running, the users do not feel cumbersometo switch databases.
