Remodeled .NET Pet
Shop Making Brisk Sales
NJDX, The KISS OR-Mapper™ for .NET, Provides Simpler and
Faster Infrastructure
Santa Clara, Calif. February 7, 2006: A
small team of software engineers has discovered a simpler approach to
building pet shops that sell fast.
Prajakta Bahekar, Neelima Sangeneni, and Renu Kolli have re-architected
the Microsoft .NET Pet Shop application by using Software Tree’s NJDX
object-relational mapping (OR-Mapping) technology, which removes the
complexity out of .NET/database programming. The resulting application has 35% less lines of
code, provides greater flexibility, and delivers superb performance.
The .NET Pet Shop
application is designed to show the best practices for building
enterprise n-tier applications on Microsoft’s .NET platform. In this ASP.NET-based web
application, classes are defined to represent domain model objects like
products, users, addresses, and orders. These domain model objects are stored in relational
databases (e.g., SQL Server, Oracle) using a data access layer (DAL). The
original DAL implementation, which uses raw SQL and low-level database
APIs, is hard to understand and maintain.
“Remodeling the Pet Shop required
us to replace a fragile and inflexible data access layer with a sturdy
and supple layer,” comments Prajakta. “The challenge was to cleanly replace the original
layer without making any changes to the existing object model, the
existing database schema, and the existing client code.”
Said Neelima, “There was
quite a bit of mismatch between the original object model and the
relational model; the existing implementation bridged that mismatch with
many complex SQL statements incorporating complicated joins buried inside
the DAL code. The NJDX
OR-Mapping technology, with its intuitive GUI tools, came in very handy
as it provided a non-intrusive, lightweight, and flexible data
integration framework that can easily and efficiently bridge the gap
between any object model and any relational schema.”
Renu
says, “Using NJDX helped us eliminate the complex spaghetti code
involving tedious SQL statements and their elaborate processing. We have achieved a cleaner
design, a smaller and more intuitive code base, and an apparently higher
performance implementation of the .NET Pet Shop application in a short
timeframe. For example, the
new DAL implementation with NJDX shrunk the code size of the Order module
from 234 lines to 68 lines (a 70% reduction). Overall, the NJDX DAL layer has 35% less code compared
to the original implementation.
Best of all, the new implementation can work with any backend
database including SQL Server, Oracle, and IBM DB2.”
“Clean design, simpler code, quick development,
high performance, database independence… what more can you ask for?” says
Damodar Periwal, President and CEO of Software Tree. “NJDX is based on some well
thought-out KISS
(Keep It Simple and Straightforward) principles that emphasize
simplicity, efficiency, and pragmatism. It is gratifying to know that Prajakta, Neelima, and
Renu could easily create a simpler and faster implementation of a
sophisticated enterprise class application like .NET Pet Shop using NJDX,
our patented OR-Mapping product.
We invite all .NET developers to reap the benefits of using this
versatile and practical product in creating higher-quality applications
with improved productivity.”
