Just about every non-LANSA application contains source code that
validates data before
information is inserted,
updated, or deleted in
the database. Even
though these rules are
critical to safeguarding
the integrity of
enterprise data, they
are often duplicated in
multiple programs in
today’s mixed platform
environments. Not only
is this a maintenance
nightmare, but also it
can introduce validation
variations and
application
inconsistencies.
In LANSA, business
rules critical to
enforcing data accuracy
are stored centrally in
its metadata Repository
rather than in the
database or application.
This locks down
system-wide validations,
calculations and other
business rules by
delivering a completely
independent Data
Services Layer that
governs all database
access. With LANSA’s
Repository, these
business rules,
algorithms and
calculations reside
within the Repository
and are not sprinkled
across many programs.
Changes made to these
Business Rules,
algorithms and
calculations do not
require the client
programs to be
recompiled or
redeployed, whether the
client is a .NET or IBM
i application.
Implementing a Data
Services layer for LANSA
Open for .NET
dramatically reduces the
time and cost associated
with traditional
application development
and maintenance.
