The author details the challenge of converting XQuery to SQL using local LLMs in an enterprise setting, hampered by limited and diverse training data. Initial attempts with parsing-based methods and prompt engineering proved insufficient for varied or complex queries.
This article focuses on optimizing Databricks SQL architecture for sustainability and cost-efficiency, emphasizing choosing the correct warehouse size and automating workloads. It provides guidelines for different needs, from light queries to high-concurrency production environments, and suggests using Auto-Stop to prevent idle compute costs.
This hands-on guide focuses on performance tuning in Databricks SQL, detailing how to diagnose and fix bottlenecks. It teaches methods like reducing data scans, optimizing joins, and leveraging caching to make queries faster and cheaper, thereby avoiding common mistakes that lead to high latency and wasted resources.
LLMs excel at querying SQL databases due to SQL's precise nature and abundant training data, making it a natural interface. However, LLM agents struggle significantly with NoSQL databases, a common production data store, primarily because NoSQL lacks the specificity and consistent syntax found in SQL.
This article presents a novel approach to debugging Android app performance by leveraging SQL queries against Perfetto traces and feeding the output to AI for automated analysis. This method allows developers to quickly identify and rank performance bottlenecks, significantly speeding up the optimization process compared to manual timeline exploration.
This article introduces 40 advanced SQL window functions essential for data scientists. It highlights the importance of mastering these features to excel in data manipulation, aggregation, and analysis beyond basic SQL.
This content introduces ReefWatch, a Coral-powered production triage agent designed to investigate production incidents by querying various systems. It details how the agent discovers connected tools at runtime, correlates evidence across different sources, and provides an inspectable UI for query results.
This guide explores optimizing Delta tables by addressing common performance issues like small files and data scattering. It introduces the OPTIMIZE command to consolidate tiny files into larger, more efficient chunks, significantly reducing I/O overhead.
O artigo critica o uso de bancos de dados de teste desatualizados como AdventureWorks em 2026, destacando problemas como esquemas antigos e falta de dados financeiros complexos. Ele propõe a utilização de datasets modernos e abrangentes que incluam dados financeiros equilibrados e informações fiscais e de folha de pagamento internacionais para um teste mais realista.

Data analytics is a highly sought-after career path due to the increasing demand for data-driven insights. A data analytics course in Pune can equip individuals with industry-relevant skills like Python, advanced Excel, and SQL, leading to high-paying job opportunities.
This content details how to transform an interview-style SQL query into a production-ready, testable, version-controlled workflow, applying software engineering principles.
This article explores SQL Window Functions, focusing on their practical application to solve complex business problems. It aims to empower readers to utilize these functions beyond the basics for more sophisticated data analysis.
The author shares their experience with DB Explorer, a free database client that replaced five different tools in their daily workflow. They highlight its unified interface and support for multiple engines, including PostgreSQL, MySQL, SQL Server, Oracle, and DynamoDB.
This article introduces SQL Window Functions as a powerful solution for data analysis problems like running totals or ranking within groups, which cannot be solved by `GROUP BY` due to its row-collapsing nature. It emphasizes their ability to compute values for each row based on other rows without losing original data.
