Converting RDF to SQL/RDBMS

I have found that there开发者_如何学编程 are a number of projects that can provide conversions from SQL to RDF. Is there anything that can go from RDF to SQL? It would preferably use the same mapping as SQL to RDF.

I have no idea if this utility works or not, but I did some googling around and found it.

I recommend using RDF2X to convert RDF dumps to PostgreSQL or any other relational database.

It was tested on terabytes of data, you can read my thesis for more info.

The best solution I have found so far is the D2RQ/Update extension to D2RQ. It is currently experimental though. http://d2rqupdate.cs.technion.ac.il/

We can convert the data to text/XML using SPARQL and load the data into SQL data base using SSIS. Or we can completely use SSIS
