The basic idea, construction, working principles and characteristic of remote transaction mirror image are presented in this paper. We analyze and compare similarities and differences among this disaster backup scheme and others usually used. The technology of remote transaction mirror image have the advantages such as less requiring of software and hardware system platform, low-investment, being able to control and restore lost data, insuring the data consistency and integrity.展开更多

In this paper, by analyzing the common feature of database system and network courses, it proposes a network-based database technology curriculum design and fabrication methods and principles, to make the curriculum from web centric processing teaching content production to around a shared database of teaching resource center changes.展开更多

In this paper, we have developed a parallel DEA model for production systems which are composed of independent parallel subunits, so that each subunit uses its own inputs and a portion of the shared inputs to produce final outputs. Also, we will propose the models to calculate the efficiency of the whole system along with the efficiencies of its subunits. In addition to theoretical derivations, a case of 25 areas of Iran＇s Bank is used as an example to illustrate the whole idea.展开更多

The conventional data envelopment analysis model measures the relative efficiencies of a set of decision-making units with exact values of both inputs and outputs. In this paper, we propose an approach to assess parallel production systems with shared sources and bounded interval data, and also we provide a model that focuses on calculating the efficiency of the whole of a system along with the efficiencies of its components.展开更多
