Method for constructing tree structural directory in database

Abstract

The invention discloses a method for constructing a tree structural directory in a database, which relates to the method for constructing the tree structural directory in the database. The method comprises the following steps of: establishing a commonly used directory structure module used for describing a tree structure and a commonly used configuration module used for describing the information related to nodes in the tree structure in the database; and when establishing the tree structure, storing the information related to the tree structure to be established into the directory structure module and the configuration module first and then establishing a specific information-containing tree structural directory by combining the information stored in the directory structure module and the configuration module. By using the method for establishing the tree structural directory of the database, a large amount of redundant data in data storage space is reduced so that various information tables can adapt to various classification structures conveniently. Therefore, the utilization rate of the storage space such as a hard disk and / or a buffer memory and the like is improved extremely, the system development and maintenance workload is obviously reduced and the stability of the system is enhanced.

Description

Method for Constructing Tree Structure Directory in Database technical field The invention relates to a method for constructing a catalog in a database, in particular to a method for constructing a tree structure catalog in a database. Background technique In many application systems in various fields at present, it is necessary to carry out hierarchical directory management for various information, especially in large-scale systems, this requirement is more obvious. In the common hierarchical structure, there are tree structure, table structure, hierarchical structure (such as: constantly popping up sub-windows or sub-links) or a combination of simple structures, etc. Among them, the tree structure can show the relationship between the data very carefully And is widely used. Currently, in the method of establishing a tree-like relationship for each piece of information in a database, it is usually necessary to add parent node field information to each information table ...
