访问控制技术在web信息系统中得到大量应用,相较于传统的自主访问控制模型和强制访问控制模型,基于角色的访问控制(RBAC)具有更强的灵活性和经济性,本文在此基础上引入组织概念,并采用动态权限,提高了效率。
Along with bioinfomatics softwares appear one after another,how to supply convenient computing services to bioinfomatics researcher is getting more and more important.In the background of bioinfomatics computing,a architecture layered as Portal,application services,key services,resource is presented in this paper.According to this 4-layered architecture,a new bioinfomatics service platform which is based on Web services is constructed in JAVA language and other tools such as ECLIPSE.And the author introduce the realization mechanism in detail.
In order to helping biological researchers to solve the problem hard to find,to learn and to in tool using completely,a new versatile web station,named biological study service platform(BSP),has been developed,which allows users to learn and use biological tools efficiently online.It mainly has three components,that is,software pool,software forum and web workstation.Software warehouse was designed to collect tools for users and also provide tool tryout;tool forum was designed for tool study and using experience intercourse and web workstation was founded for tool use and data manage.Also,it can be used as the teaching and learning platform for teachers and students in life science.It can be accessed from the follow linkage: 218.57.145.30:9999/biosp/.Besides,in order to assist researching work well,more new tools will be added,and more software will be developed continuously in this web station.
