or try the free opensource software, R, it has a SQL package that could automate the data retrieval.

这几个,还有sas,到底那个最容易用在大量的data analyses上?

Depending on the size of data you are working on. If it is really gigantic (100G plus), you have to go with 64 bit Matlab or R package. It will still be time consuming.

It also depends on what you want from the analysis, real time or not.

I am not familiar with SAS and minitab.

If small budget, try R. Otherwise, go with Matlab which has good database package and client support.

I did try R for a while, but it looks so complicated.
Where can I find or get SQL package for R?

For me, it is quite simple. I just want know gene profiling of partial samples from one set of microarray data which already published online. For example, people already performed a miRNA microarray for 6 different breast cancer cell line(see link: http://www.ebi.ac.uk/arrayexpress/browse.html?keywords=E-TABM-596&expandefo=on) . I want to know gene expression change ratio by comparing two of them.

Any simple software can be used for this kind of data retrieve?
