uqa

UQA (Unified Query Algebra) is a multi-paradigm database engine that integrates relational, text retrieval, vector search, graph query, and geospatial capabilities into a singular algebraic structure, leveraging posting lists as a unified abstraction. It provides an SQL interface compatible with PostgreSQL 17 and operates as both a standalone Python implementation and an embeddable database, facilitating complex queries that span multiple paradigms and enabling seamless integration of operations across diverse data types. Notable features include Boolean algebra structures for query optimization and graph-posting list isomorphism for graph data compatibility, enhancing its versatility in modern data applications.
