| Abstract: | In order to efficiently deal with image access in the power dispatch and management information system,three resolutions are offered,i.e.images are converted to binary stream and stored in a database,image files are submitted to file system in web server,and image data is stored in XML document.The advantages and disadvantages of the three solutions are also analyzed and their applied occasions are given.The three solutions have been successfully applied to several large-scale projects such as DMIS in Jiang... |
