What is Software Architecture 2022?

An algorithm is a set of rules that are used in solving problems or calculations. You can also say that it is a procedure for solving mathematical issues in a finite number of steps that are frequently by recursive operations.

Software architecture is something we all use every day without realizing it. Software architecture is the foundation of technology most people don’t know exists. It can send a quick message via WhatsApp or order take-out online from your favorite software architecture is integral to the overall system design. It is the foundation for all innovation. Why don’t you hear more about software architecture?

Software Architecture: The Foundations

Everything is straightforward to use in the age of technology. This is also the purpose of good software: high-quality services in an easy-to-use environment. The overall abstraction of any software product makes them seem simple and easy to utilize. However, building complex software applications involve complex processes involving many elements. Coding is only one of them.

After collecting business requirements from a business analyst the developer team starts working on the software specification which is shortly known as SRS. Then it goes through various stages like acceptance testing, deployment, maintenance, etc. Each step of the software development process follows a set of actions that are part of this Software Development Cycle (SDLC).

Software architecture is created and documented during the Software Development Life Cycle design phase. This article will focus on Software Architecture, a critical element of the Software Development Life Cycle (SDLC).

What is Software Architecture?

Software Architecture refers to the basic organization of a system. It describes a structured solution. It describes how the components of a system communicate and are connected. It is used as a guideline for software development and as a basis for software applications.

Software architecture is a collection of items that makes software development easier.

  • Software architecture is the structure of a system.
  • It describes the behavior of a system.
  • This describes the relationships between components.
  • Software architecture defines communication structure.
  • They are designed to balance the needs and interests of all stakeholders.
  • Software architecture can influence team structure.
  • Software architecture is focused on the most critical elements.
  • Software architecture is a way to capture early design decisions.

What is Software Architecture Characteristics?

Architects divide architecture characteristics into broad categories based on operation, seldom appearing requirements, structure, etc. Here are some factors that are often considered.

  • Characteristics of Operational Architecture
  1. Available
  2. Performance
  3. Reliability
  4. Tolerance for low faults
  5. Scalability
  • Structural Architecture Characteristics:
  1. Configurability
  2. There is potential for expansion
  3. Supportability
  4. Portability
  5. Maintainability
  • Cross-Cutting Architecture Characteristics:
  1. Accessibility
  2. Security
  3. Usability
  4. Privacy
  5. Possibilities

SOLID principles in Software architecture –
Each character in the SOLID text defines a principle of software architecture. To avoid making mistakes in product strategy, this SOLID principle must be followed. Software architecture must follow the SOLID directions to avoid architectural or development failures.

Software Architecture

Architecture is a blueprint that outlines a system. It is a way to organize the system’s complexity and create a communication and coordination mechanism between components.

  • This solution provides a well-structured solution that addresses all technical and operational needs while optimizing common quality attributes like performance and security.
  • This involves important organizational decisions regarding software development. Each one of these decisions has a significant impact on the quality, maintainability, or overall success of the final product. These include:
    • Selection of the structural elements and their interfaces that will make up the system.
    • Behavior is defined by the collaborations between these elements.
    • These structural and behavioral elements are combined into a large subsystem.
    • Business objectives are aligned with architectural decisions.
    • Architectural styles guide the organization es.

Software Design

Software design is a design blueprint describing how elements fit together and how they work together to meet the system’s requirements. These are the objectives of a design plan:

  • To discuss system requirements with customers, managers, and marketing personnel.
  • Assist in the development of the project by acting as a guide.
  • Assist with the implementation tasks, including design, coding, and integration.

Architecture’s Goals – These are the steps before the detailed design, coding, integration, testing, and domain analysis.

Architecture is primarily about identifying requirements that will affect the structure of an application. An architectural plan that is well designed reduces business risks and creates a bridge between technical and business needs.

The following are some of the other goals of architecture:

  • Describe the system’s structure, but keep its implementation details secret.
  • All possible use cases and scenarios should be considered.
  • Always ensure to consider the requirements of all stakeholders.
  • As a responsible person must fulfill both quality and functional requirements.
  • You can reduce your goal and increase your organization’s market position.
  • The system will improve the quality and functionality.
  • External confidence can be increased in the system or organization.

Limitations

Software architecture is still a new discipline in software engineering. These are its limitations:

  • Architecture is challenging to represent because it lacks tools and standard methods.
  • There are no methods of predicting whether architecture will meet the requirements.
  • Lack of awareness regarding the essential architectural design in software engineering.
  • Poor communication and lack of understanding about the role of software architects.
  • Inadequacy in understanding the design process, experience, and design evaluation.

Software Architect’s Role

Software architects provide a solution that can be created and designed by the technical team for the entire application. The following areas should be of expertise for a software architect:

Design expertise

  • Expert in software design incorporates a variety of methods and approaches like object-oriented design, event-driven design, and many more
  • Assist the development team in ensuring the integrity of the design.
  • They should be able to review and negotiate design proposals.

Domain Expertise

  • Expertise in developing the system and plans for its evolution.
  • Assist with the requirements investigation, ensuring completeness and consistency.
  • Coordinate the creation of a domain model for the system.

Technology Expertise

  • Expert in technologies available to aid with implementing the system.
  • Coordinate the selection and implementation of frameworks, programming languages, platforms, databases, and other relevant information.

Methodological expertise

  • Expert in software development methodologies used during the SDLC (Software Development Life Cycle).
  • Select the right approach to development for your team.

Hidden Role of the Software Architect

  • Facilitates technical work between team members, strengthening the trust relationship within the team.
  • Information specialist with vast experience and knowledge.
  • Protect your team members from outside forces that could distract them or bring less value to the project.

Deliverables for the Architect

  • A set of clear, concise, consistent, and easily achievable functional goals
  • A functional description for the system that includes at least two layoffs and ers decomposition
  • The system concept and it design with at least two layers of decomposition
  • An overview of the operator attributes and timing and the implementation and operations plans
  • Document or process that ensures functional decomposition and controls interfaces.

Qualitative Attributes

Quality can be defined as excellence or being without defects or deficiencies. The system’s quality attributes are distinct from its functionality.

Quality attributes make it easier to distinguish resound sound and a lousy system. Attributes are general factors that impact system design, runtime behavior, and user experience.

They can be classified under –

Static Quality Attributes

Static quality attributes are directly related to architecture, design, and source code and reflect the organization’s structure. They are not visible to the end-user, but they can have an impact on development and maintenance costs.

Dynamic Quality Attributes

This dynamic quality attribute reflects the system’s execution behavior. These refer to the system’s architecture, source code configuration, and deployment parameters.

The user can see them at runtime (e.g. throughput, robustness, and scalability).

Quality Scenarios

Quality scenarios are ways to prevent a mistake from becoming a disaster. Based on the attributes of each scenario, they can be broken down into six sections.

  • Source a person, physical infrastructure, software, hardware, or an external entity generates the stimulus.
  • Stimulus is a condition that must be considered when it appears on a system.
  • Environment The stimulus is only available under certain conditions.
  • Artifact: A system or part thereof, such as processors, communication channels, persistent data, processes, and so on.
  • Response is an activity that occurs after the stimulus has been received. It can include recovery from faults, detection faults, disabling event sources, etc.
  • Response measures Should measure the responses to ensure that the requirements are met.
