我们正在开发我们产品的新版本,并且我们希望实现一个功能,用户可以查看旧数据以进行应用程序做出的疾病预测。例如,用户可以选择回到过去查看一年前的预测。在数据库级别需要发生的是获取归档数据。数据库中的表数量约为 200 个,其中需要返回到旧状态的表
I read about Flashbacks and although they seem to be used more for recovery, was curious to know if they can be used.
1> Would it be possible to use Flashbacks?
2> If yes, how would it affect performance?
3> If no what could be some other options?
Thank you
