Study Notes

Architecture Description & Conceptual Model

ISO 42010 defines key terms related to system architecture, including architecting, architecture, conceptual model, concern, mission, model, modeling, modeling language, notation, and stakeholder.
Architecting refers to the activities related to defining, documenting, maintaining, improving, and ensuring proper implementation of a system's architecture.
An architect is the person or team responsible for the system's architecture.
Architecture represents the fundamental organization of a system, including its components, their relationships, and guiding principles for design and evolution.
A conceptual model is a representation of concepts and their relationships.

Types of Systems

Systems are always relative, with the concept of a "System of Interest" (SoI) and "Enabling Systems".
A System of Systems (SoS) is composed of multiple systems that may operate independently but work together to achieve a common goal.
Examples of SoSs include an aircraft, an airport, and the human body.
A system can be seen as part of a larger SoS or decomposed into smaller SoSs.
The “performance” of a System is often increased because of data distribution and delegation ("offloading") to different tiers (client, application, and data).

Multi-Tier Architecture

The multi-tier architecture is a distributed architectural style where components are grouped into tiers:
- Presentation Tier: The user interface that interacts with users (often web-based or mobile applications).
- Application Tier (Business Logic): This tier handles the application's business logic, processing commands, and coordinating functionalities.
- Data Tier: This tier manages data storage and retrieval through a database or file system.

Business Process Model

Business processes are a set of activities performed by humans or machines to achieve a specific goal.
They are triggered by events and aim to deliver value to customers, often crossing functional boundaries within an organization.
Business Process Management (BPM) is a structured approach for managing business processes, focusing on identification, design, execution, documentation, monitoring, and control to align processes with strategic goals.
BPM seeks to improve efficiency, reduce errors, and enhance organizational responsiveness to change.
Process owner is the individual responsible for managing a specific process.
Key Performance Indicators (KPIs) are metrics used to track and measure the performance of a process.
Business Process Modeling involves creating diagrams, descriptions, and information that provide insights into the organization's business processes.
The purpose of modeling business processes is to:
- Design information systems that align with organizational activities.
- Understand the organization's processes, tasks, and personnel involved.
- Determine process initiation and termination points, as well as responsibilities and locations.
