The Fundamental Dilemma of Natural Language Querying in Databases: The Two Sides of the Same Coin—Text to SQL and Ontology—and the Bottleneck to Implementation Abstract: The core goal of enterprise natural language database querying is to eliminate technical dependencies, enabling business and management personnel to autonomously retrieve data using natural language. Despite decades of pursuit, standardized implementation has yet to be achieved. The industry typically decomposes this into two stages: Text to SQL syntax conversion and ontology-based semantic understanding. In reality, both are part of a progressive closed loop toward the same objective. Text to SQL is mature and can be productized, while ontology, constrained by historical evolution, business jargon, security, and compliance, cannot be universally replicated—making it the core bottleneck of natural language querying. This article, drawing on enterprise practices, explains the intrinsic relationship between the two, analyzes the root causes of ontology’s non-universality, and proposes a lightweight, customized implementation path. Keywords: Natural language query, Text to SQL, ontology, data semantics, enterprise data intelligence 1. The Origin of the Problem Since the widespread adoption of relational databases, the ability for non-technical users to autonomously query data has been a persistent challenge. Reducing the barrier to data access and unlocking business productivity are core demands of enterprise data intelligence. Although SQL is designed to be close to natural language, technical barriers remain in areas such as multi-table joins, aggregations, and business metrics. Non-technical users cannot independently perform complex queries. Traditional approaches all have fatal flaws. The first is the technician-mediated model: business requirements must be translated into SQL by technical staff. This model frequently suffers from semantic deviations, mismatches between technical metrics and business understanding, and delayed response times, resulting in inefficiency and severely limiting data value. The second is customized visualization tools, where technicians package fixed interfaces for business users to select from. This approach is extremely inflexible; new requirements necessitate iterative development, and in-depth analysis cannot be covered. This creates a structural contradiction: simpler approaches are insufficient, while flexible ones are difficult to master. In the era of large models, Text to SQL is seen as a breakthrough, enabling one-click conversion from natural language to SQL. However, in large-scale implementation, models often suffer from incorrect table selection, field identification errors, and misjudgment of business metrics, resulting in SQL syntax that is correct but semantics that are invalid. This demonstrates that natural language querying is not merely a syntactic engineering task but a dual closed loop combining syntactic adaptation and semantic alignment. The lack of ontology semantics is the core crux that has prevented breakthroughs in this field for decades. 2. Two Sides of the Same Coin The intrinsic unity of Text to SQL and ontology: the industry has long studied them separately, leading to fragmented approaches. In reality, they serve the same goal and form a complete progressive process for natural language querying. a) Text to SQL: A universal and mature standardized module The essence of Text to SQL is mapping natural language to standard SQL syntax. Its structure is clear, its logic is unified, and it aligns closely with human expression. Leveraging large-scale pretraining on massive corpora, large models can stably handle routine queries such as single-table, multi-table, aggregation, and grouping. This module has three major advantages: strong generality—a single engine can adapt to mainstream databases like MySQL and Oracle, with mature engineering; mature supporting technologies such as prompt engineering, syntax validation, and error correction that effectively mitigate hallucinations; and scalable deployment supporting private batch deployment. It offers low marginal cost through multi-scenario reuse. Text to SQL is no longer in the research phase but is a mature technology ready for batch implementation. b) Ontology: Enterprise-specific, non-replicable infrastructure Enterprise data ontology primarily involves establishing precise mappings between business concepts and data entities, clarifying the actual business meanings of tables, fields, metrics, and lineage. It is not a general theory but a unique semantic dictionary for each enterprise. Enterprise data systems exhibit four major individualized characteristics: data evolves over years, leading to historical artifacts such as pinyin abbreviations, mixed old and new usage, and redundant tables; industries and departments have proprietary business jargon; different definitions exist for the same concept; core data structures are trade secrets and cannot be connected to external general platforms; and business dynamics require continuous ontology maintenance. These characteristics make ontology an enterprise-specific semantic fingerprint that cannot be standardized or batch-replicated. c) Synergy: A complete closed-loop execution system The complete process of natural language querying is: ontology handles semantic translation, converting business concepts into data entities; Text to SQL handles syntax conversion, transforming requirements into executable SQL. Both are unified under the goal of enabling non-technical users to accurately and autonomously query data. The industry misconception is that technology companies only optimize Text to SQL, leading to accurate syntax but incorrect business results. Some enterprises blindly build generic ontologies disconnected from actual business, resulting in vague semantics and ineffective tools. Only deep synergy between the two can form an effective closed loop. 3. Core Bottleneck: The Deep Roots of Ontology’s Non-Universality Text to SQL is fully mature—the core difficulty in implementing natural language querying is the inability to standardize enterprise ontology. This is determined by the inherent properties of data and business. First, enterprise databases are living fossils: data systems are not built once from a standardized blueprint but evolve through business changes, personnel turnover, and outsourcing. This unique historical structure cannot be batch-parsed through general rules and requires manual deep consolidation. Second, business semantics have natural barriers: industry-specific terminology, departmental divergent metrics, and tacit business knowledge cannot be learned by general models; they can only be accumulated through in-depth investigation and historical document sorting, and are not transferable. Third, business dynamics and compliance lock out universal paths. Business and metrics are continuously updated, requiring dynamic ontology maintenance; government and enterprise data security and compliance are strict, with core structures prohibited from external connections, completely blocking universal product deployment. Fourth, ontology construction has case-specific customization. The degree of data disorder and business complexity varies greatly across enterprises, making construction timelines and effects unpredictable, and experience non-reusable. This forces ontology construction to exist only as a consulting service, not as a standardized, productized offering. 4. Difficulty Comparison In the overall engineering effort, ontology is the core challenge of implementation; the difficulty levels of the two modules are severely imbalanced. Text to SQL is a quantifiable, optimizable, batchable technical problem, while ontology is a non-quantifiable, non-universal enterprise-specific engineering task requiring deep manual effort. In terms of actual investment, ontology semantic consolidation accounts for more than 80% of the work. Once ontology is established, even simple visualization tools can meet most business needs. Conversely, without ontology, no advanced Text to SQL can produce effective results. The industry has long put the cart before the horse, focusing on model optimization while neglecting semantic infrastructure—this is the key reason for years of stagnation in this field. 5. Implementation Logic A realistic path of lightweight, customized solutions: given the reality that ontology cannot be universalized, enterprises must adhere to the core principle of “universal tools, customized ontology” and advance construction in a lightweight manner. First, build ontology lightly by focusing on core business domains—sales, finance, operations, etc.—without pursuing full data coverage. Use code search, business interviews, and sample validation to quickly establish key semantic mappings, reducing costs and cycles. Second, adopt an architecture combining a generic Text to SQL engine with a local private ontology repository. The generic tool handles syntax conversion, while the local ontology handles semantic alignment, ensuring efficiency without leaking core data and meeting security and compliance requirements. Third, adopt a semi-automated model of “model assistance + human final review.” Models assist with schema sorting and field classification, while business and technical experts perform final review and correction. Establish a dynamic iteration mechanism to ensure ontology effectiveness. Finally, adapt to enterprise scale differently: large government/enterprise organizations build internally with their own teams; small and medium enterprises rely on industry service providers using lightweight industry templates with fine-tuning. 6. Conclusion The essence of enterprise natural language querying is to bridge the semantic gap between business language and machine data. Text to SQL and ontology complement each other. Ontology is the foundational layer, solving semantic definition and mapping; Text to SQL is the upper-level tool, completing syntax conversion and execution. Industry practice shows that Text to SQL is mature and ready for widespread adoption. However, ontology, constrained by historical evolution, business differences, and security compliance, has no standardized universal solution. The future will long see a pattern of generic tools combined with local customization. This is an inevitable consequence of data complexity and business diversity. Only by acknowledging the reality that ontology cannot be universalized, abandoning the one-size-fits-all mindset, and taking a lightweight, customized, scenario-specific path can we truly break down technical barriers and achieve efficient implementation of enterprise data intelligence.
