将CDA存储到关系数据库

Question

Is it a good idea to extract data from CDA and storing it to relational database? Is it better to just store it as XML and than query it as per requirement?

Answer 1

It really depends on things like the size of the xml document, the amount of data that needs to be shredded and its relation to the size of the xml doc.
