Metabase's query builder is designed to enable non-technical users to run simple queries on a single database table, utilizing features like pulling information from related tables through Foreign Keys, modifying columns, and creating new ones with mathematical expressions. The tool allows for the use of saved questions as tables in the query builder, facilitating more complex queries by using SQL to generate intermediate results or subqueries, which can then be used in further querying processes. While it doesn’t offer the same power as some other tools, it provides accessibility to a broader range of users within a company. The platform is committed to enhancing its query builder with additional features that will cater to both non-technical and technical users, focusing on areas where SQL falls short, and aims to redesign its interface for better accessibility. Metabase also supports optimization of slow queries through materialized views or batch processing, ensuring efficiency in handling compound queries that bring value to users. The team encourages feedback on potential improvements, prioritizing features based on user interest.
