Graph Database Query Interoperability via Global Column Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional databases, including relational and key-value stores, are inadequate for managing rich, highly connected data due to their inflexibility and inability to efficiently handle complex queries and dynamic relationships, leading to performance issues with large datasets.
Innovation Solution
A graph database system that uses global column indexing and partitioned indexing schemes to optimize querying, supports multiple query languages, and maintains statistics for index optimization, enabling efficient storage and analysis of connected data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional relational or key-value databases are used to store connected data, then data storage is simple and straightforward, but query performance deteriorates and the system cannot efficiently handle complex relationships and dynamic data structures
Solution Approach 1:
The patent segments the database into multiple partitions, where each partition stores a subset of the graph data. This segmentation allows parallel processing of queries across different partitions, improving query performance while managing complex relationships. Each partition can be independently optimized and queried, reducing the computational burden on any single node.
Solution Approach 2:
The patent introduces a multi-dimensional indexing structure that goes beyond traditional single-dimension indexing. By creating indexes on multiple columns and relationships simultaneously, the system can efficiently navigate complex graph relationships in multiple dimensions, transforming the way queries traverse connected data and significantly improving performance.
2Adaptability or versatility
If the database supports multiple query languages with different data models, then interoperability and flexibility improve, but system complexity and mapping overhead increase
Solution Approach 1:
The patent introduces an intermediary layer that sits between the storage engine and multiple query language interfaces. This intermediary handles the mapping and translation between different query languages (such as SPARQL, Gremlin, and Cypher) and the underlying unified graph storage model. By centralizing the translation logic in this intermediary layer, the system achieves multi-language support without requiring complex point-to-point mapping between each language pair, thus reducing overall system complexity.
3Speed
If global column indexing is implemented to optimize query performance, then query speed improves, but storage requirements and index maintenance overhead increase
Solution Approach 1:
The patent implements a universal indexing structure that serves multiple query languages and data models simultaneously. Instead of creating separate indexes for each query language or data model, the system designs a unified global column index that can be efficiently utilized by SPARQL, Gremlin, Cypher, and other query languages. This multi-functional index reduces the total storage requirements compared to maintaining separate indexes for each language while still providing optimized query performance across all interfaces.
Data Source
AI summary
Methods, systems, and computer-readable media for query language interoperability in a graph database are disclosed. Data elements are inserted into a graph database using one or more of a plurality of graph database query languages. The graph database query languages comprise a first graph database query language associated with a first data model and a second graph database query language associated with a second data model. The data elements are stored in the graph database using an internal data model that differs from the first and second data models. One or more of the data elements are retrieved from the graph database based at least in part on a query. The query is expressed using a different graph database query language than the graph database query language used to insert the one or more retrieved data elements.
