Method Design
Concepts
·
Code Reusability--Process code only needs to be
written once. Cleanly debugged and generated program units can be
used in other modules and applications.
·
Configuration Management--Storing code in a
central location in a common format, namely, the database, supports
rapid code retrieval and simplifies the maintenance task. The
database can also be used for tasks like code searches and code
backup.
·
Proactive Tuning--Because the SQL is stored in
the database, Remote DBAs and developers can extract and test the methods
used in applications. Information garnered from these tests can be
used to pinpoint areas where indexes are needed, identify tables
that can benefit from caching in the buffer pool, and other
performance tuning techniques.
·
Application Portability--Because code is
resident in the database, it (the code) is immune from platform
changes like operating system changes or multiplatform execution.
Portability from platform to platform is simplified because the
executable code will not require recompilation.
·
Process Cross-Referencing--Documentation of a
method's use in an application is simplified through the use of a
data dictionary. Method calls can be examined to identify data and
program dependencies. Maintenance is also simplified because all
applications that reference a particular entity can be identified
easily.
