Intermediary Database Structure for Multi-Model Querying

The patent introduces an intermediary data structure with a hierarchical tree-like structure that acts as a mediator between users and multiple database models. This intermediary layer translates queries from different database models into a unified interface, enabling adaptability across various database systems without requiring users to learn multiple complex query languages. The intermediary structure resolves the contradiction by absorbing the complexity of multiple database models while presenting a simplified, standardized interface.

The patent applies preliminary action by pre-assigning multi-character expressions to all entities, attributes, and entity occurrences in the database structure before queries are executed. These expressions are stored in advance in the hierarchical tree-like structure, enabling rapid query processing through pattern matching against the pre-established expression framework. This preliminary structuring eliminates the need for complex real-time processing during queries, thereby improving speed while the system architecture manages the complexity through automated expression generation and matching mechanisms.

The patent segments the data access system into distinct layers: the underlying database models remain intact with their original structures and data, while a separate hierarchical tree-like interface layer handles the unified access operations. This segmentation allows the interface to translate and transform data queries without modifying the original databases, thereby maintaining data integrity and preventing information loss. The hierarchical structure enables selective access to different levels of data granularity, ensuring that information is retrieved accurately while presenting it through a simplified, standardized interface.
