This standard specifies the classification, coding principles and design procedures of information classification and coding systems for computer-aided management systems (CMS) of machinery industry enterprises. This standard is applicable to the compilation of classification and codes of information for industrial and non-industrial management systems. 2 Referenced Standards
The provisions contained in the listed standards constitute the provisions of this standard through reference in this standard. The versions shown in + are valid at the time of publication of this standard. All standards will be revised. All parties using this standard should mention the possibility of using the following standards to develop new services. GB7026-86 Standard 1: Guidelines for the preparation of information classification and coding data GB7766 Standard 2: Guidelines for the principles and methods of information classification and coding 3 Definitions
This standard adopts the following definitions.
3.1 Information
Something with a certain meaning
3.2 Information
A formalized form of things, events or instructions. It is suitable for human or automatic communication, interpretation or processing. 3.3 Information
The attributes and characteristics of information storage, distinguish and classify certain characteristics and methods, form a certain classification system and non-sequential order, in order to manage and use information.
3.4 ​​Coding
The process of coding based on the base class. 3.5 Code
A code is a set of unique, easy-to-recognize and easily-used numbers for calculation and human identification. It is called "code" 4 Basic Provisions
4.1 Codes generally use the following characters:
Arbitrary numbers 0~-9
Letters A~Z (except 0,[).
Approved by the Ministry of Industry and Information Technology on September 30, 1998 and implemented on December 1, 1998
JB/T SH23-1998
4.2 Information Classification The design of the coding system should be standardized. It should be entrusted to various technical personnel and management personnel such as design, process, quality, finance, personnel, planning and sales.
4.3 The information classification coding method should be implemented as an enterprise standard: The information classification coding standard should comply with the provisions of GB7026. 5 Basic principles of information classification
5.1 5.1 Scientificity
Select the stable essential characteristics of things as the basis and basis for information classification. 5.2 SystematicityWww.bzxZ.net
Arrange the specific characteristics or features of the selected things and concepts in a certain order to systematize and form a scientific classification system. 5.3 Usability
It is necessary to set up narrow categories so as to ensure that when new things and concepts are added, the established classification system will not be completely disrupted. When the system is in need of information management, the existing system will be extended and refined on the basis of the current classification scheme. 5.4 Compatibility
It should be consistent with relevant standards (including international standards). 5.5 Applicability
It should meet the requirements of users within the system as much as possible under the premise of meeting the overall standards. 6 Basic characteristics of abbreviations
6. 1 Uniqueness
A code can only uniquely identify one classification object. F.2 Extensibility
Old codes must be allowed. New codes are allowed. 6.3 Simplicity
The code structure must be as accurate as possible and have only a limited amount of information. 6.4 Rationality
The code structure should be compatible with the classification system. 6.5 Applicability
The code structure should reflect the characteristics of the object as much as possible, and be convenient. 6.6 Standardization
For the same type of code, the code writing format must be unified. 7 Information classification coding system design process
The information classification coding system design process includes: a) Determine the system has been marked, and analyze the data: b) Determine the elimination list:

Figure 1 Interest integration coding system design process used 1 Determine the system goal, data investigation and analysis based on the overall system objectives to determine the information model, comprehensively understand the relevant information of the enterprise, collect various types of original certificates, lists, etc.: analyze the nature of various types of information, define the information name + provide cumulative design data, .1.! Preliminary investigation
The basic situation of the enterprise shall be investigated step by step, including the enterprise's natural situation (the enterprise's history, scale, ownership, contracts, management system and logistics situation, etc.) and production and operation situation (plan, production type, product variety, output, equipment, process, production capacity, quantity, cost, product stability, product development trend, inventory, sales and service situation, etc.). The system's monthly code should be used and a preliminary investigation report should be submitted.
7.1.2 Current situation investigation
Based on the information determined by the preliminary investigation, an in-depth investigation shall be conducted on the enterprise's current information classification, coding situation and product structure data, and all necessary information (invoices, reports, ledgers, various summary tables, various documents, technical and economic indicators, etc.) shall be collected; the production and operation of the enterprise shall be analyzed. Logistics and information flow, eliminate false information and duplicate data, ensure the accuracy and reliability of information, 7.1.3 Feature analysis
Use the feature table method (that is, list the names of data elements) to analyze the characteristics of the information received, unify the definitions of concepts, data items and data elements that need to be unified, so that users have a common understanding and eliminate errors in information exchange. Definitions should use standard terms as much as possible. 7.2 Determine the list
Step by step, sort the information received by category, list the list or name table, and use text and digital codes to describe it as quickly as possible (that is, sort the data items according to the order of the information characteristics). 7.3 Formulate coding rules
. 3.1 Each information has a unique code. The information code is generally composed of a classification code and an identification code.Classification code is the code indicating the category of information, identification code is the code indicating the characteristics of information such as structure, material, process, etc. The classification and abbreviation of information shall comply with the provisions of Chapter 5 and Chapter 1. The classification and coding of information can be found in Appendix A (suggested Appendix). 3
JB/T8823—1998
7.3.2 The structure of information classification coding system generally adopts the decimal classification system. In the decimal classification system, each layer is displayed in the form of a tree structure. The position of each code position depends on the previous position and is represented by 0 to 9. Each code position expresses a fixed meaning, as shown in Figure B1 of Appendix B (suggested Appendix). In addition, Latin letters in accordance with the provisions of 4.1 can also be used as auxiliary code symbols when necessary, and the system structure can be determined according to the needs of enterprise information operation. 7.3.3 In order to ensure the correct input of the code, the longer codes and some related codes should be checked to detect the errors caused by their input, transmission and other operations. The calculation method of the checksum can be found in 2.4.2 of GB7027-86. 4. ... 7.6 Release and implementation
The classification system, coding system and various codes of the financial department shall be released and implemented according to the enterprise standards. JB/T8823-1998
