Explaining System Architecture in Detail: an Overview of IQCode.


A system architecture diagram is a visual representation of the structure and organization of a software system. It outlines the relationships between components and levels of abstraction. Developing a software architecture is crucial in defining project goals and guiding the design and development of a new system.

What is a System Architecture Diagram?

A system architecture diagram is a tool used to define the structure and organization of a software system. It provides a high-level view of the system’s components, their relationships, and the flow of data between them. The diagram aids in understanding the system’s design and assists in communication between developers, stakeholders, and clients.

Benefits of Using System Architecture

Using a system architecture diagram provides multiple benefits, including a clear understanding of the system’s structure and organization, better communication between developers and stakeholders, easier troubleshooting and problem-solving, and improved documentation of the system’s design.

System Architecture Diagram Examples

Here are a few examples of system architecture diagrams:

System Test Architecture Diagram: A diagram used to illustrate the structure and organization of a system test.

Content Assignment System Architecture Diagram: A diagram used to illustrate the structure and organization of a content assignment system.

E-Learning System Business Architecture Diagram: A diagram used to illustrate the structure and organization of a business architecture related to e-learning systems.


A system architecture diagram is a crucial tool in developing a software system. It provides a high-level view of the system’s structure and organization, aiding in understanding, communication, and problem-solving.

The Importance of System Architecture

System architecture is crucial in understanding how a system functions and interacts with other systems and outside entities. It defines the connections between all components and the data flow within the system. When we talk about system architecture, we are usually referring to the software architecture instead of physical structures.

The system architecture must adapt as the system is used. For instance, an airport’s architecture might have the control tower and departures lounge in the same building, but it could evolve to have the control tower in a different location. We describe the system based on its parts and their functionalities, similar to how we describe data.

In conclusion, understanding system architecture is critical to ensuring optimal system performance and effective communication with other systems and users.

Understanding System Architecture Diagrams

A system architecture diagram is a visual representation of a system’s component architecture that provides an overview of the system’s major functions and the relationships between various components. This helps to understand component-component relationships and system functioning.

To streamline development, it is recommended that development teams are divided into different regions. The client-side development is handled by one team, backend by another, and database by the last team. A single architecture diagram can help all teams work together and use it as a reference when designing their new system. This provides a common language for communicating system design and tracking the status of the system.

Benefits of System Architecture

Here are some advantages of having a well-defined system architecture:

– A visual representation of the system architecture through a diagram helps in communicating the requirements to stakeholders and developers. This aids in software development and prevents future integration and operational issues.
– Customer satisfaction should be a key factor in the decision-making process. Knowing what they want and building a product that meets their needs will increase the chances of success.
– A system architecture diagram also demonstrates the value of a supplier’s product or service to the customer’s business. It reflects the supplier’s market position, making it more critical for high-value suppliers.
– Keeping system architecture diagrams up-to-date is essential. Outdated diagrams can cause problems, including regulatory compliance issues, which can lead to hefty penalties that damage your company’s reputation.

Note: Regularly updating the system architecture will ensure compliance with regulatory standards and industry best practices.

System Architecture Diagram Examples

Understanding system architecture is crucial to understand its implications. In this section, we will delve deeper into system architecture.

System Test Architecture Diagram

This diagram illustrates how the software is tested using data from operational layers and business users. Metrics like failed test cases and time to fail are gathered to test the code. Usage data, such as the number of requests, usage frequency, and data volume used for each request, is evaluated to improve the system. End-user feedback and actions are also taken into consideration to optimize the software further.


// This code describes the workflow-based architecture of the Content Assignment System

// Define the process of assignment tracking
function assignmentTracking(assignment, student) {
// Code for assigning the assignment to the student

// Define the database structure
const database = {
// Code for storing and retrieving assignments and student information

// Define the procedures for receiving and assigning assignments
function receiveAssignment(assignment) {
// Code for receiving the assignment
assignmentTracking(assignment, student);

// Define the procedures for assigning assignments to students
function assignToStudent(student) {
// Code for assigning the assignment to the student
assignmentTracking(assignment, student);

The Content Assignment System has a workflow-based architecture. The process of receiving assignments and assigning them to students is carried out through assignment tracking. The database structure stores and retrieves assignments and student information. The procedures for receiving and assigning assignments are implemented through the receiveAssignment() and assignToStudent() functions.

E-Learning System Business Architecture Diagram

This system consists of the following activities: data collection, analysis, presentation of learning material, evaluation, and closing of the learning process. The system architecture diagram represents the customer’s requirements and illustrates all components of the system. The student registers themselves through the client application, and their information is saved in the database. Then, they gain access to the learning material to begin the process.

Application Architecture: Design and Categories

The design of an application considers various factors, such as software architecture, which outlines the software’s structure, components, data models, and programming models. Additionally, it details how the application is built, tested, and maintained. There are three main categories of an application architecture, including the software architecture, software development model, and maintenance model. An application architecture must be flexible to adapt to technological advancements and customer requirements while building a strong foundation for future development.
