如何在MySQL中创建拆分账单的数据库结构？

我有一个事务表，其结构如下：

| transaction_id | customer_id | amount | transaction_type_id | status |
transaction_id => is the id of the transaction
customer_id => is the customer id who did the transaction
amount => Total transaction amount
transaction_type_id => Type of transaction 
status => status of the transaction => pending, complete, canceled

split_bill
split_bill_id|transaction_ids | initiator | total_amount
split_bill_id => id of the split bill
transaction_ids => All the customer transaction id separated by comma
initiator => the customer_id who initiate split bill
total_amount => total of the bill

split_bill_request
split_bill_request_id | split_bill_id | customer_id | status
split_bill_request_id => id of split bill request
split_bill_id => id of the split bill
customer_id => id of the customer who receive split bill request from initiator
status => status of the request pending,accept,reject

我想为我的程序创建拆分账单功能，该功能的工作原理如下：

| transaction_id | customer_id | amount | transaction_type_id | status |
transaction_id => is the id of the transaction
customer_id => is the customer id who did the transaction
amount => Total transaction amount
transaction_type_id => Type of transaction 
status => status of the transaction => pending, complete, canceled

split_bill
split_bill_id|transaction_ids | initiator | total_amount
split_bill_id => id of the split bill
transaction_ids => All the customer transaction id separated by comma
initiator => the customer_id who initiate split bill
total_amount => total of the bill

split_bill_request
split_bill_request_id | split_bill_id | customer_id | status
split_bill_request_id => id of split bill request
split_bill_id => id of the split bill
customer_id => id of the customer who receive split bill request from initiator
status => status of the request pending,accept,reject

客户输入要拆分的账单的总金额

客户添加另一个客户（n个客户）以拆分账单，并指定金额

将为状态为“待定”且指定金额的拆分账单中的所有客户进行交易

其他客户将收到拆分账单请求，以拒绝或接受拆分账单

如果其中一个客户拒绝拆分票据请求，则交易将被取消，但如果所有客户都接受该请求，则交易状态将为“完成”

到目前为止，我已经找到了解决方案，通过创建主拆分账单表和拆分账单请求，如下所示：

| transaction_id | customer_id | amount | transaction_type_id | status |
transaction_id => is the id of the transaction
customer_id => is the customer id who did the transaction
amount => Total transaction amount
transaction_type_id => Type of transaction 
status => status of the transaction => pending, complete, canceled

split_bill
split_bill_id|transaction_ids | initiator | total_amount
split_bill_id => id of the split bill
transaction_ids => All the customer transaction id separated by comma
initiator => the customer_id who initiate split bill
total_amount => total of the bill

split_bill_request
split_bill_request_id | split_bill_id | customer_id | status
split_bill_request_id => id of split bill request
split_bill_id => id of the split bill
customer_id => id of the customer who receive split bill request from initiator
status => status of the request pending,accept,reject

我不知道这是否是正确的方法，您能建议另一种方法吗，因为我对拆分账单表中的交易ID或执行此操作的有效方法有疑问，并且因为我没有修改交易表的权限？

这个问题很主观，所有与设计相关的问题也是如此。在事务ID字段上有一些值得思考的地方：它们只是“请求”，因为它们是“挂起的”。但实际上，您不会将它们移动到某个单独的表中，因此我认为将它们存储为“请求”是没有帮助的。它们只是“拆分”，尽管未经确认。哦，“事务ID”的想法很糟糕！
