How to create a database like carsmall

I have a set of values under different categories, I would like to use the command ' load ' to at once call the values into my workspace instead of using xlsread.

What is the problem with xlsread? Using xlsread reads the data into a variable in the workspace, which you can split up and re-assign into other variables if you wish to, so what advantage do you imagine from another method?

How do you imagine that 'loading' this data would be different from xlsread?

How is the data stored: are these arrays or scalars?
