The document outlines a request to redesign three tables that contain zip code data for Los Angeles. The population table has unique zip codes, the business table has unique IDs with potential multiple businesses per zip code, and the crimes table has unique IDs as well, with multiple crimes per zip code. A proposed solution includes removing the 'councildistrict' from the business table and creating a new district table with zip code as the primary key and councildistrict as a secondary column.
