Challenge

Many business users and non-technical stakeholders struggle to interact with databases due to limited SQL knowledge. Analysts or developers are often required to translate even simple questions into SQL queries, causing delays and inefficiencies. Users are unable to independently explore data, test queries, or quickly generate insights, which slows decision-making and reduces productivity.  

The main challenge is to build a solution that allows users to input natural language questions and automatically generate accurate SQL queries, enabling them to access and analyze data efficiently without relying on technical staff.

Cabot’s Solution

Cabot’s solution makes data exploration effortless by letting users ask questions in plain language and instantly get accurate answers—without needing to write SQL. An intelligent translation layer interprets each query, while a user-friendly interface ensures results are easy to understand and actionable for all employees.

Queries are automatically validated, enriched with schema context for precision, and displayed through a clean, interactive Streamlit interface. This approach accelerates data analysis, reduces dependency on technical teams, and turns complex database operations into a simple, self-service experience.

Process

Cabot implemented a step-by-step development cycle, incorporating feedback at every stage to ensure continuous improvement. Key steps included:

  • Environment Setup – Configured the Streamlit environment and supporting tools for building the prototype.
  • UI Design – Created a simple and interactive interface using Streamlit components to make the app accessible for non-technical users.
  • AI Integration – Developed prompt templates and integrated the LLM for accurate SQL generation from natural language inputs.
  • Execution & Display – Enabled real-time execution of generated SQL queries and displayed results within the application.
  • Testing & Demo – Validated the solution with mock databases and test queries, followed by a demo session for stakeholders.

Key Features

  • Natural Language to SQL Conversion – Users can ask data questions in plain English, and the system automatically generates accurate SQL queries.
  • Interactive Streamlit Interface – Simple, intuitive UI built with Streamlit for easy use by non-technical stakeholders.
  • Schema-Aware Query Generation – Context from database schema is incorporated to improve the accuracy of generated SQL.
  • Real-Time Query Execution & Results – Generated queries are executed instantly, and results are displayed directly in the app.

Challenges Faced and Solutions Provided

Challenge: Converting vague natural language questions into accurate SQL queries while keeping the interface simple for non-technical users.


Solution: The application automatically converts natural language questions into accurate SQL queries, validates the results, and presents them through an intuitive interface. This empowers non-technical users to explore data independently and make faster, informed decisions without relying on developers or analysts.

Impact

The automation of SQL query generation through natural language input brought significant operational improvements to users. Key benefits included:

Faster Data Access
Non-technical users can now explore and analyze data independently, reducing dependency on developers and enabling quicker, informed decisions.

Reduced Errors in Query Results
Schema-aware AI and validation checks ensure generated SQL queries are accurate, minimizing mistakes and inconsistencies in data retrieval.

Improved Productivity
Users spend less time waiting for analysts to translate questions into SQL, allowing teams to focus on higher-value tasks and data-driven insights.

Enhanced Accessibility and Usability
The intuitive Streamlit interface makes complex database interactions simple, empowering all users - technical or non-technical - to interact confidently with data.

Conclusion

By combining Streamlit, Python, and Azure OpenAI Service, Cabot developed StreamQuery, a proof-of-concept application that converts natural language questions into accurate SQL queries through a simple, interactive interface. This solution empowers non-technical users to explore data independently, reducing reliance on developers and accelerating decision-making.

The project showcases Cabot’s ability to simplify complex data workflows with AI-driven automation and a user-friendly interface. Tested with stakeholder feedback and sample databases, the solution improves data accessibility, minimizes errors, and supports faster, more informed decisions.
