Raven DB到SQL服务器（NoSQL DB到关系数据库）

Is there a way to convert/migrate NoSQL database data(Raven,Mongo,Couch ) into SQL server data? Since some NoSQL databases lack reporting tools, would be easier if I could move the data to SQL and work off that directly (just for data analysis, querying, reporting needs).Comments appreciated.Is there a way to convert/migrate NoSQL databas
