Software Architecture and Design – Goals, Principles and Some Key Considerations

Explanation:

Philippe Kruchten, Grady Booch, Kurt Bittner, and Affluent Reitman derived and processed a definition of structure depending on work by Martha Shaw and David Garlan (Shaw and Garlan 1996). Their definition is: click here

“Software architecture encompasses the collection of significant decisions about the organization of your software system including the selection of the structural elements and their interfaces by which the system is composed; behavior as chosen in collaboration among those elements; composition of these structural and behavioral elements into larger subsystems; and an architectural style that guides this organization. Application architecture also involves operation, usability, resilience, performance, recycling, comprehensibility, economical and technology constraints, tradeoffs and visual concerns. ”

In Habits of Enterprise Application Buildings, Martin Fowler outlines some common recurring themes when explaining architecture. He recognizes these themes as:

“The highest-level breakdown of the system into its parts; the decisions that are Hard to change; there are multiple architectures in a system; precisely what is architecturally Significant can change more than a system’s lifetime; and, in the long run, architecture boils Straight down to whatever the important stuff is. ”

Computer software program architecture is the process of defining and coming up with a solution that is well structured and meets all of the technical and operational requirements. The buildings should be able to take into account and improve after the common quality attributes such as performance, security, and management.

The main focus of the Software architecture is the way the major elements and components within an app are being used by, or communicate with, other major elements and components within the application. The selection of data structures and codes or the implementation details of individual components are design concerns, they are rather than an architectural concerns but sometimes Design and Structures concerns overlap.

Before starting the architecting of any software, there are several basic questions that we should work to get answers for. They are as comes after:

How the users of the system will be interacting with the system?

How will the application form be deployed into production and managed?

What are the many non-functional requirements for the application form, such as security, performance, concurrency, internationalization, and setup?

How can the program be built to be versatile and maintainable over time?

What are the system trends that might impact the application now or after it has recently been deployed?

Goals of Application Architecture

Building the passage between business requirements and technical requirements is the key goal of any software architecture. The purpose of architecture is to identify the needs that affect the basic composition of the application. Great architecture reduces the business risks associated with building a technical solution while a good design is flexible enough in order to deal with the changes that will occur over time in software and hardware technology, as well as in user scenarios and requirements. An architect must consider the overall an end result of design decisions, the inherent tradeoffs between quality attributes (such as performance and security), and the tradeoffs required to addresses user, system, and business requirements.
