By SAS do you mean
Statistical Analysis Software? Designed to do complex statistical analysis of data?
It's true that Access, SQL Server and Oracle have gradually gained some analysis tools in addition to their core features of sorting, selecting, filtering and reporting.
But they are databases with low analysis power vs. an analysis engine that can store its data.
Access can sort of work like a spreadsheet but it doesn't replace Excel. Acess can sort of work like a number-crunching program but it doesn't replace Matlab. The focus and feature sets are different.
No, I don't use SAS or SPSS
