PROC DMDB before PROC ASSOC

proc dmdb batch data=sampsio.assocs out=dmassoc dmdbcat=catassoc; id customer; class product(desc); run;

proc assoc data=sampsio.assocs dmdbcat=catassoc out=datassoc(label='Output from Proc Assoc') items=5 support=20;cust customer; target product; run;

what is the purpose of the first line

why can't I just use proc assoc

Re: PROC DMDB before PROC ASSOC

I moved this discussion to the Data Mining community.  PROC DMDB creates a SAS catalog that has metadata about the characteristics of your data, which is required input for other data mining procedures.  One of our data mining experts might be able to provide more information.
