Tools to explore various datasets

Question

TL:DR - Do you know of good automated tools to explore a dataset?

Long version: I have a few different datasets to work with from most various areas of business. I wonder if there are good software/scrips that could automatically round up the following answers for me: Things I would be looking for:

• datatype of a column?
• dimension or measure?
• histogram or count of values in a column
• correlation between measures
• unique key auto-find
• import into a strongly typed data structure

Obviously I'm looking for something more than basic summary(cars). Something that goes through each column and spits out detailed analysis report
