Conversation Summary
assistant: 我来系统梳理所有数据库表中的字段、释义、用途和计算口径。先全面查阅已有的业务知识和数据表信息。
assistant: Now let me check the actual database tables to get exact field lists:
assistant: Now let me get detailed column info for all the key tables:
assistant: The BI aggregate tables don't exist in this DB yet. Let me check the MySQL side for some of these source tables:
assistant: MySQL user tables are not directly named matching the Go code names. Let me look at the MySQL config tables for the course-related structures, and also check the PostgreSQL for any additional fields I may have missed:
assistant: Now let me get the remaining key tables' field info:
assistant: Now let me also check the remaining PostgreSQL tables I haven't fetched yet:
assistant: OK, those tables don't exist. Now let me also check the MySQL vala_order database:
assistant: Now I have comprehensive information. Let me compile all of this into a well-organized document:
assistant: Now I can see the cut-off. Let me replace the truncated part and add the remaining sections:
assistant: The file was truncated. Let me fix it by replacing the last truncated section and appending all remaining content:
assistant: Now let me also update MEMORY.md to reference this new document:
assistant: 验证一下最终文档的完整性：
assistant: 文档完整。现在记录此次工作到当天的日记忆：
assistant: 好了，字段百科全书已梳理完成。以下是成果概要：
📊 字段百科全书已创建
