Information era, information, together with the material and energy, already are called three greatest resources of modern society.
It will provide the science leading for the information management practice, also the technique, method guide provided to information system construction and management for all levels sports organization.
As a science of basic regulation, principle and application method, SIM, a crossed, synthetic, plied science, is based on the development of informatics, management science and IT, also, other science, such as information science, librarianship, archives and documents provide it with the technique and methods.
College sports information users need to understand the information development of physical education at home and abroad in the training objectives, curriculum, teaching arrangements and so on, according to assume the task of teaching and research, the main need for teaching materials, teaching methods and research in the field of information, the information needs have social and cutting-edge features.

In each area of the distribution, the characteristic of the ancient architectures are recorded, such as story number, building materials, construction time, etc.
In this section, some principal characteristics are chosen, such as story number and story height, building materials, roof structure, construction site etc.
The story number and height are influenced by building materials (will be discussed in the following part), economics and culture.
In the analysis, some principal attributes are analyzed, including story number and story height, building materials, roof structure and construction site.
