Data bank system and data access method thereof

Abstract

The data base system features that it is established based on business data grade classification. It includes at least at least one first set with unique first grade classified based on the requirement of the user; the second set related with the first set and providing business data related to the first set; and the corresponding relation for correlatively positioning between the first set and the second set via utilizing the uniqueness of the first classification. Correspondingly, the system has data access method including data adding course, searching course, displaying course and authority realizing course.

Description

technical field [0001] The invention mainly relates to a database system and its data access method. Background technique [0002] With the widespread use of information devices such as personal computers and the expansion of online services through networks such as the Internet, the number and types of databases required are rapidly increasing. [0003] Current computer database systems include the following types, namely, network-shaped databases, tree-shaped databases, relational databases (Relational Database, RDB) and object-oriented databases (Object-oriented Database, OODB). When these conventional databases deal with massive data, they use a database field based on several logically related and clearly descriptive features to represent the uniqueness of such information. In the process of information processing, there are many types of data fields for data storage and query, and each data must have a corresponding field type. When setting, it is necessary to estimat...

AI Technical Summary

Problems solved by technology

[0006] 1) In setting the database fields, there must be several fields that clearly describe the characteristics, resulting in many fields describing the characteristics, and information management and users are easy to confuse which is important information

[0007] 2) In the information processing process, the number of words represented by the data field type needs to be estimated and set, that is, the storage length of the information storage is limited, and it is necessary to artificially judge and estimate the stored information fragments, which is likely to lose valuable information;

[0009] 4) When personnel are required to operate database fields, there are many steps and complicated operations, which may easily cause damage to database files, which is not conducive to maintenance

[0010] 5) The title of each dialog box is fixed in the traditional method of utilizing database access data, so a large number of dialog boxes and database tables need to be set up,
