As a jave developer, working for a social security data-center, I am working with DATA everyday, these data are from everywhere-Oracle, Sql-server, excel sheet or txt files, then I have to integrate these data together and do some complex data analysis. But I reallized that SQL is so bad in completing these work. Some developer recommended me to use R language, and some peple suggest me to try esProc which is free of downloading on(, I would appreciate any better tools and thanks for your sharing.
