[galaxy-user] How good is Galaxy as a data repository and for cross-experiment querying?

I'm looking for a tool to manage all of our experimental data, not only the workflow but the storage and meta-analysis as well.  I know Galaxy is known for workflow management, but I wasn't sure if it can be used as a cross-experiment repository and querying tool.  An example of the query we want to do is for a given gene, find out which cell lines/tissues it's been expressed in all of our RNA-seq and microarray experiments.  Does Galaxy have this feature or should I look elsewhere?  Thanks.
