Method and platform capable of customizing enquiry based on service combination

Abstract

The invention provides a customizable query method and a platform on the basis of service composition. The method comprises: describing own demands to the platform by a user through an appointed client end visible component and through operations of selecting and filling the attribute value of the component, analyzing the initial state and the target state of a data query request, then, searching and combining a corresponding basic service calling sequence, then, executing basic services in the sequence, thereby obtaining a result set which contains user expected result data, and generating a final result to display to the user through screening, sequencing and assembling. In the method, the user describes own demands to a system actively, the system can effectively adapt different individualized demands of different users through receiving user description and dynamic analysis processing, the application system development work load and the later maintenance cost are lowered, and the friendliness of a data query application system is improved, which enables the user to customize data query actively and enables inquiry to be flexible and convenient.

Description

technical field [0001] The invention belongs to the field of computer data management, and in particular relates to a service combination-based customizable data query method and a platform thereof. Background technique [0002] In the traditional web-based data query, the web application system provides an independent data query condition input page for each data query function. The query condition input page is the entrance of this data query function, and the background logic corresponding to the page is fixed and implemented in a system hard-coded way. For the function of inputting complex query conditions, the system provides an input method for simple query conditions such as "and", "or" and "not" to form complex query conditions. [0003] When users query data, they first select the required function page from the function set provided by the system, then select and fill in the query conditions and submit the data query request according to the method specified by th...

AI Technical Summary

Problems solved by technology

If the query condition expected by the user is not the condition input page item provided by the system, the query requirement cannot be accepted by the system; if the user does not care about some data in the query result obtained by the system and wants it to be filtered for data analysis, Or if you want to focus on a certain part of the data, the query processing method with a fixed output result format of the system cannot meet the needs of this kind of user preference

[0006] Second, the data query functions supported by the application system have been classified in advance, and the user's query action is limited to a page that provides the query function

This method leads to low data query efficiency, increased user workload, and poor system friendliness

[0007] Third, when developing an application system, it is necessary to do hard-coding work for each data query function, and the workload is heavy and repetitive.

[0008] Fourth, after the data query application system is developed and put into use, if there are new functional requirements, the system cannot automatically adapt to the changes in requirements

The logical rationality of the SQL statement generated by this processing method cannot be verified before execution, and a reasonable SQL statement cannot be associated with the corresponding query function, so it is not reusable
