Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0055] The present invention can be applied to a system or software implemented based on a database. The database is organized according to a certain data model and stores data collections in secondary storage. This kind of data collection has the following characteristics: it is not repeated as much as possible, and serves multiple applications of a specific organization in an optimal way. Its data structure is independent of the application program that uses it. Unified software for management and control.

[0056] In the prior art, for data with a tree-like storage structure, the lower-level organization is usually used to record the storage method of the upper-level organization ID. In this way, when a certain level node has N-level upper-level nodes or M-level lower-level...

Abstract

The invention discloses a method and a device for storing and inquiring data. The method for storing data is applied to a database provided with a tree-shaped storing structure and comprises the following steps: acquiring path information expressing a storing relation of an upper grade and a lower grade of nodes in all grades in the tree-shaped storing structure in the database; distributing the path information to the nodes in all grades and storing, wherein the path information comprises the ID information of the nodes at a grade and the ID information of all nodes in the upper grade of thenodes. By distributing the path information for expressing the storing relation of the upper grade and the lower grade to an organization in each grade, all upper grades or all lower grades of an organization can be directly inquired at one step by the path information distributed to the organization in the grade, thereby greatly improving the inquiring efficiency of data in the database of the tree-shaped storing structure.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, to a data storage and query method and device. Background technique [0002] The database is a warehouse that organizes, stores and manages data according to the data structure, so that the computer can be used to realize the automatic management of production data. Therefore, the database has been widely used in the production management of various departments in various enterprises. [0003] At present, when using a database for data storage, for data with a tree-like storage structure, the storage method of recording the ID (Identity, identity number) of the upper-level organization is usually used by the lower-level organization, specifically: assign IDs to each level of organization ID, which is in one-to-one correspondence with the corresponding organization. E.g, figure 1 It is a common tree-shaped organization chart in production management. "Group...
