Data-structures are machine-centric, not abstract relational algebra. You can understand why it's important to think about data structures for the machine. Which is a completely opposite view from relational databases, where you are supposed to not think of how data relates to the machine at all.

In practice the boundary between both is fuzzy. Processing DB data can and is often done in a row-by-row or cell-by-cell basis. Not all computations are convenient to reduce to relational algebra, at least for most practitioners. We can't all be Sheldons.
