A very common mistake in RDBMS programming include using ANY procedural
language where pure SQL will accomplish the task. I have seen many
instances of T-SQL and PL/SQL that were totally unnecessary - and both will
be considerably slower than pure SQL if the ask can be accomplished in pure
SQL.
Due to >internal< differences in implementation of the SQL language, it is
not generally a good idea to do a one-on-one comparison of T-SQL and
PL/SQL.

Oracle Database Utilities (Data Pump/SQL Loader)

Realize that Oracle natively includes ablity to define tables based on
external files (such as CLF exports from Excel) and 'heterogeneous
services' allowing data to be sourced and included in transactions even
when not stored in Oracle.

Oracle OLAP

Note that the OLAP option in Oracle is frequently overkill. In my
experience, many reports and analyses only require things like Racle's
Advanced Grouping capability - from their docco
"... CUBE and ROLLUP to produce sub-totals and crosstab reports easily and
efficiently using a single SQL statement." and "Analytic functions ...
Includes rank, moving average, and ratio-to-report."
Based on discussion in comp.database.oracle.server, and referencing Oracle's
"New Features" doc for Oracle9i, these are available in Personal, Standard
One, Standard and Enterprise Edition
A decent reference to learn these is O'Reilly's "Mastering Oracle SQL"
