My major interest is Information Science. It seems to be Science for Computer machines. But it is true that Info. Sci. is for more various fields. Info. Sci. is a general thinking on processing of somethings. It includes any kind of (data) processings. Input some data, and calculate them by certain algorithms with some data structures, and then output the result. This is an abstract analogy of WORKS, which can be for business, factory, and so forth. They are templates or patterns of WORKING. For instance, there are some Design Pattern theories in Info. Sci. Therefore, Info. Sci. can be applied to the various fields to solve problems in daily life, business issues, and so forth. Info. Sci. consists of abstract theories to answer the questions in a certain way, for a lot of problems. So, why don’t we use it more, in various scenes?
