DuckDB` is not a database for ducks, but rather an open-source relational database that allows users to work with data on their laptops and can be easily scaled up to larger storage systems. It provides a query engine that can be used on top of various data storage solutions, including object storage services like Amazon S3. The name `DuckDB` is derived from the idea of creating a "data pond" that can grow into a data lake, with users able to export their data to Parquet files and store them in cloud-based storage services. While some users may joke about ducks using the database, it is not related to the actual use of the software by humans. The most engaged users on the DuckDB community include individuals who have contributed to the open-source project or have shown enthusiasm for its functionality.
