“Loss Minimization of Web Databases by Fine Grain Approach”

چکیده
Information is the most valuable asset for organizations. One of the goals of organizations is to share their data and at the same time to enforce their policies. Web database is a combined production with database technology and Web technology. Web database is placed on the Internet, there are many security problems. The secrecy and the integrity are two important demands of security system. When database access control and the network security are addressed separately, the security systems are not optimized sufficiently as a whole. Finegrained access control (FGAC) must be supported by web relational databases to satisfy the requirements of privacy preserving and Internet-based applications. We propose a model of integrating network security with criterion based access control to handle network security and the fine grained Web database access control simultaneously. We have implemented our model in college database and performance is evaluated. Whenever any unauthorized user altered our data a system called Web-Secure report to the authorized user via E-mail or Short Message Service (SMS). The implementation results show that how our model is suitable for web database

Introduction and discussion about three types of fine grain products and their harvesters
Fine grain products are harvested in two manual and mechanized forms. Nowadays, common combine harvesters are used, but fine grain products such as Rapeseed, Sesame and Sorghum cannot be harvested with conventional heads of combine harvesters due to the excessive grain loss in the head of the combine. Therefore, the necessity of design and fabricating machines and heads of combine harvesters be...

متن کاملSkew Minimization with Low Power for Wide Voltage Range Using Course Grain Technique
Skew is one of the most important parameter that decides the performance of the system. Though skews are reduced using two-stage(low and high voltage levels) serially connected power mode aware buffers(PMABs) using two power gating techniques-Fine grain technique at high voltage level and Coarse grain technique at low voltage level, the power consumption and area is large incase of fine grain t...
متن کاملOptimal Capacitor Allocation in Radial Distribution Networks for Annual Costs Minimization Using Hybrid PSO and Sequential Power Loss Index Based Method
In the most recent heuristic methods, the high potential buses for capacitor placement are initially identified and ranked using loss sensitivity factors (LSFs) or power loss index (PLI). These factors or indices help to reduce the search space of the optimization procedure, but they may not always indicate the appropriate placement of capacitors. This paper proposes an efficient approach for t...
متن کاملA Regret Minimization Approach in Product Portfolio Management with respect to Customers’ Price-sensitivity
In an uncertain and competitive environment, product portfolio management (PPM) becomes more challenging for manufacturers to decide what to make and establish the most beneficial product portfolio. In this paper, a novel approach in PPM is proposed in which the environment uncertainty, competitors’ behavior and customer’s satisfaction are simultaneously considered as the most important criteri...
