Unlike matter and energy, there is no consumption

Positive aspects: maximize sharing in time and space, improve efficiency and save costs

Negative aspects: Sharing brings difficulty and inconvenience to information management property rights arrangements and control, and intellectual property protection

This summer is hotter than next year. The order cannot be changed. Processability is not a simple arrangement and combination.

Objective mapping of human thoughts and social activities

Digitization, coding, serialization and structuring of facts

Mapping of data on information media

The results of information processing, extraction and evaluation

ability to apply knowledge

Data is the raw material of information, and information is the raw material of knowledge. Data covers the widest range, followed by information, and knowledge is the smallest.

Substance provides material (existence)

Energy powers (happens)

Information provides knowledge (meaning)

Information has become a more important resource than material and energy. Information economic activities based on the development and utilization of information resources have expanded rapidly, gradually replacing industrial production activities and becoming the main content of national economic activities.

Manifestations

Informal channels: information flows directly from information producers to information users

Formal channels: Information flows to information users under the control of the information system

Narrow sense: Information resources are equivalent to knowledge, data and information, and only refer to the collection of information itself.

Broadly speaking: an organic collection of information, information technology and information personnel. It is a multi-element concept involving the entire labor process including information production, processing, dissemination and utilization.

Information personnel use specialized information technology means to collect, select, process, and analyze original data to form information products, which are then delivered to those who need them.

Information production and development sub-goals

Information utilization sub-goals

Information management mechanism sub-goals

Strategic management is implemented by national departments using economic, legal and necessary administrative means. It organizes and coordinates the production, development and utilization of information through national policies, laws and management regulations, in accordance with national macro-objectives, without affecting national information sovereignty and information Get the most reasonable development and most effective utilization under the premise of safety.

Grassroots organizations such as government departments at all levels, information agencies and enterprises are responsible for implementation. Facilitate the information needs of personnel at all levels within the organization, rationally organize and develop information, and provide them with the utility value of the information.

Technical perspective: Mainly studies the collection, processing, and processing of information using manual and computer methods, which refers to orderly storage, easy retrieval, and delivery to specific users.

Economic perspective: Mainly studies the formation, development, characteristics and operation model of the information market, information industry, and information economy based on the production, circulation and utilization of information, the optimal allocation of information resources, and the evaluation of information economic benefits.

Administrative and legal perspective: Regulate and control information based on government functions and legal means

Humanistic perspective: Based on the study of the influence and construction of moral, ethical, and cultural factors in information flow control, such as information privacy

Creation (production/release) phase: This is the initial stage of the information cycle and the starting point for information life cycle management. It is necessary to maintain the consistency of document formats, specifications and metadata descriptions. (Scholars write papers and publish them)

Collection: manual collection or automatic acquisition (collected from CNKI to CNKI)

Organization: Provide an orderly structure for information collections to form an organic whole to facilitate the access and utilization of information (description and indexing)

Storage: The basis for realizing the value of information. The main task of this stage is to rely on relevant storage application technology to change the information stored on the corresponding carrier and ring from an unavailable state to an available state, and the available state to an available state. Xinxi's management, sharing, protection, backup, recovery, replication and other functions are realized in an automated way. (Save to system)

Utilization: It is the purpose of information life cycle management. Information utilization is the process in which users effectively use the provided information. How to ensure that information is used effectively? 1. Establish a professional database 2. Provide professional information navigation 3. Carry out information value-added services (retrieval, reference, citation)

Cleaning (destruction/recycling) stage: As information ages and loses value, a lot of information will no longer have value after a period of time. The main work of this stage is to establish scientific and clear rules for data recycling. (delete)
