The "platform" in "cross-platform" to me generally means the operating system on which a program is running - and .Rdata files are perfectly portable between R on Linux, MacOSX, Windows, Solaris etc versions. You didn't mention portability to other statistical packages. You also didn't mention needing SQL, or what you wanted to do with your databases. I figured I'd just mention .Rdata files for completeness! There's also RJDBC and RODBC which can interface to anything with a JDBC or ODBC interface on your system. A .RData file could be considered as a serverless NoSQL database. There's a GSOC proposal to investigate interfaces to NoSQL databases and some info here: http://rwiki.sciviews.org/doku.php?id=developers:projects:gsoc2010:nosql_interface Isn't it odd that the open-source R community has developed functions for reading in proprietary SAS and SPSS format files, but (AFAIK) the commercial sector doesn't seem to support reading data from open-sourced and open-specced R .Rdata files?
