 No
doubt, enterprise architecture and design are the most important phases
of every software development life cycle (SDLC). These phases define
every aspect of the system: behavior, user friendliness, robustness,
extensibility, scalability, flexibility, maintainability, –

all features that guarantee long life of the system, if done
professionally. In many cases, the quality of the finished software is
directly proportional to the quality of the initial design. A weak or
flawed design often leads to rewrites in later releases, when new
functionality cannot be added in a straightforward way.
Performance and scalability issues also often arise
as the result of architectural weaknesses. Investing time and effort in
creating a proper design is important, as resolving such issues can be
hard and costly once a system has been put into production use.
Creating a solid system, however, requires a high level of expertise
and experience in software development.

Architecture and design include everything that is
a part of the description of how the identified data sources are to be
connected to the user requirements. Architecture contains the models of
the system architecture and encompasses significant decisions about the
following:
- The
organization of the system
- Technology
assessment
- The
selection of structural elements and their interfaces by which the
system is composed, together with their behavior as specified in the
collaboration among those elements
- The
composition of these elements into larger subsystems
- System
integration
- Cost
projection
- The
architectural style that guides this organization, these elements and
theirs interfaces, their collaboration, and their composition.

Design activities elaborate further architectural
artifacts into blueprints that will be used for implementation of a
system through the set of abstract or real classes. Usually, more than
70% of development expenditure on the average system is spent after its
first release for maintenance and functionality enhances, to reflect
changing domain requirements. Appropriate, well-performed analysis and
design phase allows dramatically cut these expenses. Custom software
development is an investment. In addition, as with any substantial
investment, planning is crucial. Since system architecture and design
are part of a large planning effort, it is critical to have it done
carefully and in full.
Eltrong services include: system specifications,
system design and development, system architecture, and operational
criteria. Our customers benefit from our extensive past experience in
project evaluation, scheduling, cost projection, supervision, and
implementation. Our skills in architectural design and system
integration will result in significant cost-savings. In addition to
achieving the quality, is the fact that our key personnel are Sun
Certified Enterprise Architects and Microsoft Certified System
Developers.
Also, because system performance is as important as
user friendliness, for large projects, we can create performance
simulation models that take into account everything from detailed
hardware and software configurations in combination with software
design choices and user loads to approximate final system performance
as a function of chosen architecture. We suggest such performance
testing to be provided at the earliest stage possible, to forecast
system performance in production environment and take necessary actions
if they are necessary, towards its improvement.
Eltrong utilizes contemporary industry standards
including ANSI, UML, RUP, MDA, XMI, XML, analysis, design and
integration patterns, to achieve the best quality of architecture
planning and design.
