Embodiment Construction

[0056] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0057] The implementation of the invention is divided into two parts: the creation and maintenance of data tables and data fields, and data entry, maintenance, query and display of the created data tables.

[0058] First of all, when creating a custom table, this technology will judge whether the name of the custom data table conforms to the preset definition. If it does not conform to the preset definition, it will prompt an error message and refuse to save it. If the name conforms to the preset definition, continue Determine whether there is a data table with the same name in the database, if it exists, return an error message and refuse to save, if there is no data table with the same name in the database, pass the check, and save the re...

Abstract

The invention discloses a method for directly self-defining the field of a database, comprising the following steps of: A1, receiving self-defined data table information input by a user from a WEB page, wherein the data table information contains the name of a data table; A2, receiving added field information from the self-defined data table, wherein the field information contains field name and field type; A3, judging whether to continue adding the self-defined data table and the field information; and A4, confirming to finish creating a self-defined table and a field. The invention also discloses a device for directly self-defining the field of a database. The method and device for directly self-defining the field of the database in the invention are widely used and simple and convenient and has the effects of lowering the development difficulty of operation of the database and greatly reducing development work time and labor cost.

Description

technical field [0001] The invention relates to the field of computer data processing, more specifically, to a method and device for directly implementing a custom field on a database. Background technique [0002] Database (Database) is a warehouse that organizes, stores and manages data according to the data structure. It was produced 50 years ago. It is no longer just storing and managing data, but transforming into various data management methods required by users. There are many types of databases, ranging from the simplest tables storing various data to large database systems capable of storing massive amounts of data, which have been widely used in various aspects. [0003] In 1974, Ray Boyce and Don Chamberlin of IBM expressed the mathematical definition of the 12 criteria of the Codd relational database in a simple keyword syntax, and proposed the SQL (StructuredQuery Language) language as a milestone. The functions of the SQL language include query, manipulation,...
