 The SQLStore automatically creates a directory structure for database storage, placing files in `data/dbstorage_sqlstore/` within your application directory. The brick supports automatic type inference when creating tables, mapping Python types (*int*, *float*, *str*, *bytes*) to corresponding SQLite column types (*INTEGER*, *REAL*, *TEXT*, *BLOB*).
 
-The `store()` method can automatically create tables if they don't exist by analyzing the data types of the provided values. This makes it easy to get started without defining schemas upfront, while still allowing explicit table creation for more control over column definitions and constraints.
