Data Modeling Interview Question:

What is the difference between hashed file stage and sequential file stage in relates to DataStage Server?

Submitted by: Administrator

In datastage server jobs,can we use sequential filestage for a lookup instead of hashed filestage.If yes ,then whats the advantage of a Hashed File stage over sequential filestage

search is faster in hash files as you can directly get the address of record directly by hash algorithm as records are stored like that but in case of sequential file u must compare all the records.
