Problems solved by technology

[0026] Finally, in conventional relational or object-relational databases, it is never possible for a user lacking programming skills to formulate complex database queries and must rely on programs written by programmers to search and display data
so the user's options are often very limited

Embodiment Construction

[0050] The following sections describe structured natural language query and knowledge systems, an improved object-relative query language, and object-relative algebra, which illustrate various inventive features. As will be appreciated, many of these features can be implemented in a given system without requiring other systems. For example, a structured natural language query system can be implemented in conjunction with a general data platform without the need for a modified object-relative query language or object-relative algebra. Furthermore, various inventive features may be implemented in ways other than those described herein. As such, the following description is intended to illustrate and not to limit the scope of the invention.

Abstract

A structured natural language inquire and knowledge system allows user lacked programming experience to input database inquire or rule input with structured language sentence. The sentence range is superior defined by improved SQL, SCA or both pf them. The conditions appeared in natural language format inquire text definition by corresponding format. User is prompted to use defined command and conditions to arrange and structure natural language sentence. The command and conditions user selected appear as verb phrase of structured natural language sentence, and the conditions and its parameters user selected appear as adjective phrase. The sentence is separated and changed to inquire text with translation format for database inquire and rule process.

Description

technical field [0001] The invention relates to the field of object-oriented and object-related databases, in particular to structured natural language database query and knowledge systems. Background technique [0002] Relational databases have been widely used for many years. A relational database arranges data in tables containing fields. Two tables containing the same fields are related to each other. Compared with the "flat file" method (which stores all data in a single file), the method of relating tables is more malleable. [0003] Most relational database systems follow the Structured Query Language (SQL) standard. Commercial vendors produce SQL-based database systems such as Oracle, Sybase, Informix, Progress, and Microsoft Access. These systems use the SQL formal query language. Here is an example of a formal query to display the names and salaries of employees whose salary exceeds $100,000: [0004] For each employee where employee.salary>100000: [0005]...
