Many businesses face the challenge of analyzing large datasets, such as sales records, to answer specific questions like 'How much did I sell last week?' Traditional AI chatbot solutions often rely on vector databases, which are not ideal for numerical queries. These databases work by vectorizing queries and finding similar vectors, making them suitable for certain types of questions but ineffective for structured data analysis.
Vector databases serve as powerful string comparison tools but fall short when it comes to structured data analysis. They cannot handle large datasets effectively due to context window limits, making it impractical to send entire datasets to a language model (LM). This can lead to inefficiencies and increased costs, especially when dealing with extensive spreadsheets.
To address these challenges, a more straightforward approach using SQL can be employed. This method does not require advanced SQL knowledge and is cost-effective. The process involves reading data from Google Sheets, creating a PostgreSQL table, and inserting rows into it. This workflow allows for efficient data retrieval and analysis without the complexities of vector databases.
The workflow begins by connecting to Google Sheets and extracting data. Once the data is fetched, it is transformed into SQL queries that can be executed within PostgreSQL. This setup ensures that the data is structured correctly, allowing for accurate responses to queries about sales figures and other numerical data.
When querying data, it is essential to specify the schema to ensure the AI can generate the correct SQL queries. This involves understanding the structure of the data and using tools to filter and retrieve only the necessary information. By doing so, the AI can provide accurate answers without overwhelming the system with excessive data.
After setting up the PostgreSQL database, it is crucial to test the system by asking specific questions about the data. The AI should be able to return accurate results based on the queries executed. Continuous improvement of the AI's prompting and query execution is necessary to enhance its performance and reliability.
As the system evolves, there will be opportunities to refine the workflow further. This includes implementing upsert functionality to update existing records without deleting the entire table. Such improvements will streamline the process and ensure that the AI always has access to the most current data.
In conclusion, leveraging SQL for data analysis provides a robust solution for businesses looking to extract insights from large datasets. By following a structured workflow, companies can efficiently answer critical questions and optimize their operations. For those interested in implementing similar solutions, resources and community support are available to assist in the setup process.
