- Implemented Outdoor Fair Attendee and Device entities, including their respective controllers, services, and mappers. - Added statistics endpoint for Outdoor Fair data, allowing aggregation by day, week, month, or year. - Introduced SQL scripts for creating tables and mock data for attendees and devices. - Created a write-capable script for executing DML/DDL statements against the SHZ HighGo database. - Enhanced the existing query capabilities to support both read and write operations.
