It defines a structured solutionto meet all the technical and operational requirements, while optimizing the common quality attributes like performance and security. The Software Architect’s primary job is to help a client understand deeply the architecture they have built, understand clearly what they desire from their information systems, and help them construct a plan to get there. The architecture, or as we sometimes refer to it, the “to-be” or target architecture, is an architecture that does not yet exist; and in that sense it is prescriptive. Typically, the process involves reviewing whatever written documentation is available for the existing systems. However, in order to define, articulate, draw, and envision a future arc The following are illustrative examples of system architecture. It makes it easier to understand the whole system and makes the decision-making process more efficient. What Does a Software Architect Do? Architecture diagrams are complex schematics that are best completed by technical architects. A software architect usually must function as a proofreader who identifies mistakes in a software design and corrects them. Software architecture is a sort of plan of the system and is primordial for the understanding, the negotiation, and the communication between all the stakeholders (user-side, customer, management, etc.). We often speak of software with a “J2EE architecture,” and while it is true the framework has an architecture, the real architecture is the combination of the framework of the procured item with the host of components that exist in the implementation environment. Though for the most part, software architecture typically isn't attributed to a single person, an artiste, but rather to a school of thought, a way of building large-scale systems. This document provides a comprehensive architectural overview of the system, using a number of different architectural views to depict different aspects of the system. Selecting a Software Architect is an important decision, as the resulting architecture will impact your information systems for a long time. And finally, he has a road map and timeline for getting from his current state to the desired state. The problem with software erosion is that its effects accumulate over time to result in a significant decrease in the ability of a system to meet its stakeholder requirements. By prejudice we mean literally prejudgment. These decisions ultimately impact application quality, maintenance, performance and overall success. To support software architecture evaluation practices, several efforts have been made to provide a basis for comparing and assessing evaluation methods, document various best practices, and report the factors that may influence industrial practices. The net result has been a large series of projects that not only neglects the overall architecture but also continues to make it worse and worse, such that each subsequent project faces higher and higher hurdles of development productivity that it must overcome in order to achieve its payback. You might expect, given that we do software architecture and this is on our web site, that we would eventually try to construct this theme to say, well, nearly everyone sooner or later needs a software architect. This approach is probably the most common because it is usually built around the database, and many applications in business naturally lend themselves to storing information in tables.This is something of a self-fulfilling prophecy. These factors include: Formality of SA descriptions; modelling of SA; SA documentation; standardisation of SA… The second problem is that we are all, if you will, living in those slums; we are running our businesses with the existing systems and it is very often not feasible to tear them down in a wholesale fashion. For instance, in the restaurant industry now, there is a company called Squirrel that has by far the largest market share of the restaurant management applications. The real difference between and intentional and an accidental architecture is whether the layering was planned and executed top down, or whether the higher-level architectures just emerged from a bottom up process. So, one of the duties of the architects is to construct a series of incremental projects, each of which will move the architecture forward. The end product of this activity combined with what’s known from the current architecture is the first draft of what is called the target architecture or the to-be architecture. The last criterion, chemistry, is perhaps the most elusive. Image 1. 1. Types of Software Architects 4. Each project has come along focused very narrowly on its short-term payoff. We present a few thoughts for you to keep in mind as you consider your decision. We might talk about an architecture being “C++” or “Oracle” or “Object Oriented” (We’ve heard all these as answers to “what is your architecture?”). As detailed in my recent IEEE Software column, failure patterns result from the mismatch of the architect's skills and the role's needs at a particular time. ... to justify the reasons why you get these data. The identification of what constitutes the “major” components is primarily a matter of scale and scope, but generally starts at the enterprise level and works down through subsidiary levels. This is an area that in the past has been sorely neglected. QUALITY CHARACTERISTICS FOR SOFTWARE ARCHITECTURE 136 JOURNAL OF OBJECT TECHNOLOGY VOL. There have been multiple problems with this approach over the years, the first being that the sheer size of these projects has had a dramatically negative impact on their success. Even if you did know this information, it would not necessarily be beneficial to base your selection of an architect on it. At the completion of this process, the client knows with a great deal of certainty where he’s headed to architecturally, why his destination architecture is superior to the architecture he currently has, and the benefits that will accrue once he is in that architecture.
