Design And Implementation Of E-form System Based On Relational Database And Non-relational Database

With the rapid development of Internet in recent years, the data of applicationsystem showing a variability and explosive growth trend, which makes theapplications on Internet must have a very high scalability and compatibility. Thoughtexpansion of the system and change can be resolved through the reconstruction andtransformation of the database in the traditional relational database system, it will leadto its bloated structure and complex structure in this way. Not only greatly increasedthe maintenance workload, but also to introduce potential risks and uncertainties.Traditional relational database and can not cope with all the scenarios, it will cost aheavy price to add and rebuild the data organization of a24-hours running system.Therefore, it would be the trend to reduce maintenance costs and technicalrequirement, and develop a kind of application system which is convenient to expand.Against the current backdrop, our company puts forward an E-Form Systemwhich can process huge storage, provide high efficient data management, andexpanded easily in the future. As a core developer of this project, I was responsiblefor system requirements analysis, architecture design and core module coding andsystem deployment.Firstly, this thesis makes comparisons of the advantage and disadvantage betweenrelational database and NoSQL, and then raises a new E-Form System based onrelational database and NoSQL as a data storage way through the analysis of E-FormSystem current situation at home and abroad. This system combines both theadvantages of relational database and NoSQL to ensure the data consistency and meetdemand of highly concurrent access.Secondly, this thesis designs and brings out the E-Form System based onrelational database and NoSQL as a data storage. Finally, this thesis sums up the system's features and merits, and also comes upwith the problems of system's design and function, as well as indicates key emphasisin the following work.The system mentioned above has been on-line since17thJuly2012. During the experimental stage, the system is stable and the design of module can meet the needof actual user.
