AMIS 25 – June 2016
Large software systems must be built from modules. A module hides its
implementation behind an interface that exposes its functionality. This is computer
science’s most famous principle. For applications that use an Oracle Database, the
database is the persistence module. The tables and the SQL statements that
manipulate them are the implementation details. The interface is expressed with
PL/SQL. Developers and users of applications built this way are happy with their
correctness, maintainability, security, and performance. But when developers follow
the NoPlsql paradigm, their applications have problems in each of these areas and
users suffer. This session provides PL/SQL devotees with unassailable arguments to
defend their beliefs against attacks from skeptics. Skeptics who attend will see the
light.
