Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The task of combining multiple tables in data analysis requires significant expertise and time, making it challenging for workers with little specialized knowledge to efficiently perform this task.
Innovation Solution
An information provision system that includes an input unit for multiple tables, an identification unit to identify combinable columns and tables, and an output unit to provide the necessary information for combining tables, using methods such as Similarity-Join, Temporal-Join, and Spatial-Join, allowing workers to combine tables effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual table combining is performed by workers, then table combination can be achieved, but it requires extensive specialized knowledge and time
Solution Approach 1:
The system performs preliminary analysis of table structures, column types, and data formats automatically before the worker needs to combine tables. It pre-identifies combinable columns, suggests joining methods, and prepares combination instructions, so that when the worker executes the combination, the complex tasks are already broken down into manageable steps with guidance provided.
Solution Approach 2:
The information provision system acts as an intermediary between the worker and the complex table combination task. It provides intermediate information including column compatibility assessments, suggested join methods, and step-by-step combination guidance, enabling workers without extensive expertise to perform the task successfully.
2Ease of operation
If manual table combining is performed by workers, then table combination can be achieved, but it requires many experts
Solution Approach 1:
The system enables self-service table combination by automatically analyzing table structures, identifying compatible columns, and generating combination instructions. The information provision system serves itself by providing workers with the knowledge and tools needed to perform the task independently, without requiring workers to have extensive specialized knowledge.
Solution Approach 2:
The system bridges the gap between simple operations and complex table combination tasks by providing intermediate information and guidance. It translates complex combining requirements into simple, actionable instructions that workers can follow without needing expert knowledge.
3Ease of operation
If automated identification of combinable columns is implemented, then table combining becomes easier, but the system complexity increases
Solution Approach 1:
The system segments the complex table combination task into smaller, manageable components: table structure analysis, column compatibility assessment, join method determination, and combination instruction generation. Each segment is handled by dedicated processing modules that work independently, making the overall system more manageable and maintainable.
Solution Approach 2:
The information provision system is designed to handle multiple table combination scenarios universally. It can identify different types of combinable columns (by name, by data type, by semantic meaning) and suggest appropriate join methods for various data relationships, making the system adaptable to diverse table structures without requiring separate specialized modules for each case.

AI summary
Provided is an information provision system that can provide workers with useful information for combining tables, so that even workers with little specialized knowledge can smoothly proceed with the task of combining multiple tables. An input unit 81 receives input of multiple tables. An identification unit 82 identifies a pair of columns that are in a combinable relationship, identifies that a pair of tables to which the individual columns forming the pair belong is the pair of tables to be combined, and identifies a combine method of the tables to be combined. An output unit 83 outputs the pair of tables to be combined, the pair of columns in a combinable relationship, and the combine method of the tables to be combined.
