Training Records Database Where Can I Find Alot Of Sample Spreadsheets And Databases?

Where can I find alot of sample spreadsheets and databases? - training records database

I took the training of such programs, but they are not used in my area. So I'm not sure what I have used programs. If I could see how to use other programs I think I might be able to provide useful data for me. It would also be good, these assemblers other data submitted their columns, rows, fields, forms and queries to be seen. A little perspective can participate ways. Thank you in advance.
