Data and Information are the basic concepts and terms of Library Science,Information Science as well as Computer Science. With the advent of the Age of Big Data,Data has been widely used not only in the professional fields but in lots of other fields,which made the relationship of the two more complicated. Does the relationship belong to an equivalent relationship or an owner-member relationship? If it is an owner-member relationship,is data larger or is information larger? To clarify the relationship of the two from the interdisciplinary perspective has an important significance for managing the data and information as resources,guiding the increasingly rich information,big data practice,the education of library-information science students,and information management science students and the discussion of the theory system of the whole field of information.In this article,based on the analysis of the connotation and extension of data and information in the documents at home and abroad,the authors concluded four representative views as follows: the scope of data is larger than that of information,the scope of information is larger than that of Data,the scopes of data and information are the same,the scopes of data and the information are relative,through the conceptual analysis method,historical method and comparative method. Among the four views,the first that the scope of data is larger than that of information is the most popular because of the dissemination of the Data-Information-Knowledge-Wisdom (DIKW) pyramid which is observed and generalized from the angle of computer science. If we analyze the DIKW Pyramid deeply,we will find its logic is not appropriate,and it cant reflect the relationship among the data,information,knowledge and wisdom. In the end,the authors put forward the view that the scope of Information is larger than that of Data from four perspectives,which are philosophy,conventional opinions,historical developments of the term of data and information,and related definitions in the latest international organizations and governments documents. Information is divided into ontological information and epistemological information. Epistemological information contains data and non-data. The data can be divided into processing,meaningful data and temporarily meaningless,raw data. In addition to explicit knowledge,there is tacit knowledge which cannot be processed and is not meaningful. Wisdom,intelligence is also true. Therefore,it is not appropriate to describe the logical relationship of information,data,knowledge,wisdom and intelligence in a pyramid. 3 figs. 28 refs.
