Software architecture and software design are two aspects of the same topic. Both are about how software is structured in order to perform its tasks. The term "software architecture" typically refers to the bigger structures of a software system, whereas "software design" typically refers to the smaller structures.
Requirements analysis, also called requirements engineering, is the process of determining user expectations for a new or modified product. These features, called requirements, must be quantifiable, relevant and detailed. In software engineering, such requirements are often called functional specifications. Requirements analysis is an important aspect of project management.
This lecture provide a review of requirement engineering process. The slides have been prepared after reading Ian Summerville and Roger Pressman work. This lecture is helpful to understand user, and user requirements.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

• Architecture
• « Architecture is the fundamental organization of a system, embodied in its
components, their relationships to each other and the environment, and the
principles governing its design and evolution. » [ANSI/IEEE Std 1471-2000]
• Software Architecture
• « The software architecture of a program or computing system is the
structure or structures of the system, which comprise software elements,
the externally visible properties of those elements, and the relationships
among them. »[SEI]

Architectural Patterns
• An architectural pattern in a proven structural organization schema for
software systems
• Architectural Patterns vs Design Patterns (already seen in chapter 4)
• Design Patterns offer a common solution for a common problem in the form
of classes working together
• Smaller in scale than architectural patterns, where the components are
subsystems rather than classes
• Design Patterns do not influence the fundamental structure of a system
• Only affect a single subsystem
• They may help implementing an architectural pattern
• Some (not all) architectural patterns are described here-after

Software Architecture Patterns
15. MedTech
Pattern 1: Layers Pattern
• Helps structure applications that can be decomposed into groups of
subtasks, each of which is at a particular level of abstraction
• Each layer provides services to the next higher layer
• Services in a layer are implemented using services from the next lower
layer
• Service requests are frequently done by using synchronus procedure
calls
• Most famous example of layered systems: networking protocols

Pattern 2: Client-Server Pattern
• A server component provides services to multiple client components
• A client component requests services from the server component
• Servers are permanently active, listening for clients
• Client and server may reside in different machines
• This pattern can be considered as a form of the layered pattern with
two layers, the clients being the higher level and the server the lower
level
• Examples
• Remote database access
• Remote file systems access
• Web-based applications (browsers request from a web server)

Pattern 3: Master-Slave Pattern
• Supports fault-tolerance and parallel computation
• The master component distributes the work among identical slave
components, and computes a final result from the results they return
• Applied for instance in :
• Process control
• Embedded systems
• Large scale parallel computations
• Fault-tolerant systems

Slide 20
Software Architecture Patterns
22. MedTech
Pattern 4: Pipe-Filter Pattern
• Provides a structure for systems that produce a stream of data
• Each processing step is encapsulated in a filter component
• Data is passed through pipes
• Pipes can be used for buffering or for synchronization
• This pattern divides the task of a system into several processing steps
• The steps are connected by the data flow
• The output of a step is the input for the next step
• Common examples:
• Pipe-filter in the unix shell commands
• cat file | grep xyz | sort | uniq > out
• Compilers

Software Architecture Patterns
24. MedTech
Pattern 5: MVC Pattern
• Model-View-Controller Pattern
• An interactive application is divided into three parts:
• Model
• Contains core fundtionality and data
• View
• Displays the information to the user
• Controller
• Handles the input from the user
• Often uses the Observer design pattern
• User input can invoke a change in the model, and in the displayed view
• Makes it easy to have multiple views of the same model
