12. PLSQL Importance
SQL statements are defined in term of constraints
we wish to fix on the result of a query. Such a
language is commonly referred to as declarative.
This contrasts with the so called procedural
languages where a program specifies a list of
operations to be performed sequentially to achieve
the desired result.
PL/SQL is most useful to write triggers and stored
procedures. Stored procedures are units of
procedural code stored in a compiled form within
the database.
