Adaptive Query Intelligence: AI-Enabled Optimization Strategies For High-Volume SQL And NoSQL Processing In Regulated Industries

This paper explores how machine learning–driven query optimization can elevate the performance, scalability, and operational resilience of SQL and NoSQL database systems deployed in high-volume financial and healthcare environments. Conventional rule-based and cost-based optimizers frequently encounter limitations when confronted with volatile workloads, uneven data distributions, and rapidly shifting access behaviors that define contemporary transaction processing and clinical data infrastructures. The central inquiry of this study examines whether adaptive, data-aware optimization models—trained on historical execution traces, telemetry signals, and workload metadata—can deliver superior efficiency and stability in such dynamic contexts. The research employs a blended methodological approach that integrates architectural framework design, algorithmic prototyping, and comparative benchmarking across representative relational and non-relational database platforms operating under large-scale transactional and analytical loads. Empirical evaluation indicates that learning-enabled optimizers meaningfully lower query response times, improve compute and memory utilization, and enhance predictability during peak data surges when compared to traditional strategies. Core contributions include the development of predictive cost estimation models, context-aware index adaptation mechanisms, and real-time execution plan adjustments powered by supervised and reinforcement learning paradigms. Collectively, the study advances the theoretical foundations of intelligent data management by embedding adaptive learning into optimization workflows, while offering practical guidance for engineering robust, high-throughput database infrastructures capable of sustaining accuracy, compliance, and responsiveness in mission-critical financial and healthcare systems.
