GB/T 37944-2019 in English

Analysis of the background of standard formulation and technical evolution

GB/T 37944-2019 "Requirements for the compilation of data models for military and civilian common resources" is a standard formulated on the basis of GB/T 1.1-2009 standardization work guidelines, combined with the common needs of the military and civilian fields for resource management. This standard aims to standardize the data model construction method for military and civilian common resources to ensure the consistency, integrity and scalability of data.

With the development of information technology, especially the advancement of big data and informatization construction, the efficient management and sharing of military and civilian common resources has become an important topic. The formulation of this standard fills the gap in the compilation of data models in the field of military and civilian common resources, and provides a technical basis for realizing cross-domain information exchange and resource sharing.

Explanation of professional terms and practical application cases

Composite Attribute:Refers to the same attribute of the same resource that needs to be described differently under different components or conditions. For example, the material attributes of a shovel: the shovel head is steel and the shovel handle is wood.

Foreign Key:A field in a data entity that refers to the association relationship formed by the primary key of other entities. For example, in a logical data model, the association between entity A and entity B can be realized through a foreign key.

Implementation suggestions

1. In actual applications, the appropriate data model compilation method should be selected according to specific business needs. For example, for a complex system containing multiple data models, the relationship and dependency between the models should be considered.

2. The data element index table and code table are the key to ensure data consistency and scalability. It is recommended to give priority to the design and management of data elements and code tables during data modeling.

3. When designing the physical data model, the characteristics of the database management system, such as Oracle, MySQL, etc., should be fully considered to reasonably configure the data item name, storage type and parameters.
