EA. Separation of Concerns Principle | Robert Corvus. Fear of making changes to your system or difficulty in following code logic are signs that your legacy code has consistently violated the Separation of Concerns principle. The Separation of Concerns principle is a cornerstone of good engineering and a hallmark of using this principle is code that’s easy to read, easy to test, and easy to refactor. The Separation of Concerns principle is about creating stable, easily maintainable code, systems that won’t fall to pieces just because you made one little change (or even sweeping changes) somewhere. Code that is separated by layers is easier to automatically test, and automated tests make code even easier to refactor. Code that is effectively organized also allows more developers to work on a project without tripping over each other in source control, either by waiting to check out a file or puzzling through a change-comparison.

Forum mall in Bangalore is not the best place to have any kind of serious dialogue and Café Coffee Day does not make things any quieter. However, it was the most convenient place for three of us, I, my friends Sanjeev Krishnan and Dr. G. N. Shrinivas (called Gun) from IIT Bombay to reconnect on the topic of technical career path and role of solution architect. It wasn’t difficult to recognize Gun after 13 years even though he has added more shine on his head.
Gun is currently an Enterprise Architect at a large MNC IT company. Vinay: Can you tell us what does a solution architect role involve? Gun: Solution architects (especially seen from a IT_Service_Provider_in_India_perspective) is a catalyst for successful service delivery. Requirements are only as perfect as the person who gathers them and documents them. Vinay: Can you tell us about your ITAC certification experience? Gun: ITAC stands for IT Architecture Certification. I can see two kinds of benefits from this certification. The Architecture Guidance Counselor | Generating Value Through Information Architecture. Children dream of becoming astronauts, police officers, movie stars, sports professionals, etc.
No one dreams of one day becoming a Software Architect. Instead, people seem to grow into architecture professions over time. With few exceptions, individuals that become business architects, data architects, application architects, solution architects, and enterprise architects grew into their respective roles rather than being guided there by a mentor or guidance counselor. There are two key elements at work here. Finding Your Path If someone were to consult a guidance counselor regarding employment in the field of enterprise / solution / technical architecture, then that person’s interests and aptitudes would be an important factor in steering toward a fulfilling and rewarding profession. The truth is that not everyone would be happy, fulfilled, and/or equipped for success in the role of an architect. Know Thyself Time To Dust Off The Piano Aptitude Rule of Thumb. Architecture domain. Structure of the "Federal Enterprise Architecture Framework" (FEAF), presented in 2001, which determined four architectural domains.[1] An architecture domain in enterprise architecture is a broad view of an enterprise or system.
It is a partial representation of a whole system that addresses several concerns of several stakeholders. It is a description that hides other views or facets of the system described. Overview[edit] Since Stephen Spewak's book called Enterprise Architecture Planning (EAP) in 1993, and perhaps before then, it has been normal to recognise four types of architecture domain: Note that the applications architecture is about the application portfolio, not the internal architecture of a single application - which is often called the application architecture. Many EA frameworks combine data and application domains into a single layer, sitting below the business (usually a human activity system) and above the technology (the platform IT infrastructure).
