Subj:   Data access using views
 
From:   madhumitha.das

Hey,

I am new to Teradata and just picking up the pace.

I read in the manuals that base views in Teradata can provide high-performance access to data. Can someone explain this in detail?

I'm aware of the fact that they act as data security layer, but what other major differences (like Spool, CPU, I/O usage, DML, Joins etc..etc) when compared to accessing data via base tables?


Thanks - Madhu Das -:)
