Application of design patterns in database access permission system
HE Deng-chao · Journal of Computer Applications · 2012
Development of database technology has an effective support to organization,storage and management of data,however the security problem of accessing to data in database applications must be addressed firstly,and database permission management and access control technology is one of the most important means to achieve database security problem.Aiming at the traditional permission management and access control methods cannot meet the growing requirements,this paper focused on the application of Bridge pattern,Abstract Factory pattern and Facade pattern in the object-oriented software design patterns in the database access permissions system,and based on ADO.NET database access technology proposed a design of database access permissions system.On the basis of the above technology,this paper preliminarily realized the database access permissions system,and improved reusability and expansibility of system to realize the maximum software reuse.
