我有2个表格的提案和提案附件。每个投标都有一个docx文件和Pdf文件。让我知道下表的设计是正确的
提案和proposal_attachments
| id | proposalNo | ProposalTitle | Status |
--------------------------------------------
| 1 | PRO 123 | sample | 0 |
--------------------------------------------
-----------------------------------------------------------------------
| id | proposal_id | version_ID | Status | fileName | filetype |
------------------------------------------------------------------------
| 1 | 1 | 1 | 1 | Sample1.docx | doctype |
------------------------------------------------------------------------
| 2 | 1 | 1 | 1 | Sample1.pdf | pdf |
------------------------------------------------------------------------
| 3 | 1 | 2 | 1 | Sample2.docx | doctype |
------------------------------------------------------------------------
| 4 | 1 | 2 | 1 | Sample2.pdf | pdf |
------------------------------------------------------------------------
应使用类似
|id| proposal_id|version_ID |Status|filetitle|fileNamedoc|fileNamePDF
