Performance, availability, and scalability concerns
often take a back seat to application functionality
until the end of a development project. However, i
Improving .NET Application Performance and
Scalability,1 the authors warn: Many, if not most,
performance problems are introduced by specific
architecture, design, and technology choices that you
make very early in the development cycle, often in the
design stage.. The strategies they recommend for
building performance into an application stress the
importance of choosing a scalable solution for
persistent data access.

Analysts also confirm that data access technology has
a significant impact throughout the project lifecycle:

Development Phase: An R.B. Webber study concluded that
coding and configuring data access typically accounts
for 30 to 40% of total project effort.

Tuning Phase: Performance and data integrity issues
often do not surface until testing.

Deployment Phase: According to a 2004 Forrester
Research survey, 66% of performance problems are first
identified by irate users calling the IT help desk.

Persistence. EdgeXtend. for C# provides
cost-effective, scalable, and high performance
object-oriented access to relational data for
Microsoft. .NET applications. EdgeXtend meets and
exceeds data access requirements at each stage of the
project lifecycle, ensuring a fast, free flow of data.
Tightly integrated features shorten development
schedules, simplify performance tuning, and ensure
enterprise-wide deployment scalability and high
availability.

In the previously referenced document, a Microsoft
architect strongly suggests that development teams
plan up front for performance: If you.re very lucky,
performance problems can be fixed after the fact. But,
as often as not, it will take a great deal of effo
to get your code to where it needs to be for
acceptable performance. This is a very bad trap to
fall into. At its worst, you.ll be faced with a
memorable and sometimes job-ending quote: .This will
never work. You.re going to have to start all over.. .

When you use EdgeXtend.s development tools, you build
runtime performance and scalability into your
application. You gain the flexibility to seamlessly
access sophisticated tuning and deployment features
without rearchitecting or additional coding.

Beyond the initial cost savings, EdgeXtend.s data
services platform reduces the risk of project failure
due to schedule overruns, poor performance, or
application failure. With dozens of large-scale
deployments at global Fortune 500 companies,
Persistence products enjoy proven success in the most
demanding enterprise systems.
