Heping Pan, Huaijie Yang · International Journal of Electrical Energy · 2013
The geophysical logging or logging has many kinds of logging methods and large amount of logging information. Logging information include log curve data (one-dimensional and two-dimensional curve data etc), image, document and so on. How to manage the massive variety of logging information is a problem worthy of study. This paper describes briefly the type of logging methods. Based on the characteristics of logging information, the data structures of different logging information have been devised. The data structures include relational data mode, large amount of data mode and graphics information pattern. According to the different data structures, access strategies have been studied, and the key technologies of logging database design have been solved.
