The research of outdoor security management system based on NHibernate

Abstract

Nowadays, companies widely apply object-oriented technology to model the business logic, and take advantage of relational database for data maintenance and management. However, object-oriented model and relational model have significant differences, which increases the difficulty of system development. Therefore, building high reliable data persistence layer based on object-relational mapping (ORM) is a good solution to the problem. In .NET area, ORM technology has aroused the attention. Not only the official Microsoft starts to support ORM technical, but also the free software, and NHibemate is a good example. At the same time Chinese developers began to use foreign ORM components in projects, and started to research ORM technology of .NET. LaserLu has proposed a detailed object-oriented data persistence design program based on .NET platform. Recently the spread of object-oriented development has brought about an increasing of new ORM tools, including the Enterprise Java Bean (EJB) of JORM, IBatis, Hibemate, Oracle's TopLink, Dynamic ORM of Cocobase Company, The Visual Business Sight Framework (VBSF) of Object Matter Company, and many other ORM middleware and standards, and domestic ORM tools have also developed. Nowadays, object / relational mapping framework does not only include NHibernate, but also OPF, Gentle.NET and Object space and so on. © 2012 Springer-Verlag London Limited.
