The document discusses software design, which involves deciding how to implement system requirements using available technology. It covers topics like software architecture, dividing a system into subsystems and interfaces. The key benefits of design are that it makes a project easier to implement, test and maintain. Good design leads to good quality software while bad design can make a project impossible. The phases of design process include architectural design, class design, user interface design, and algorithm design. Design principles discussed aim to divide problems into smaller parts, increase cohesion, reduce coupling, use abstraction, design for flexibility and testability.

Complex problems can be solved using Top-down design model, also known as Step-wise refinement, where we break the problem into parts and then break the parts into sub parts and finally soon, each of the parts will be easy to code and accomplish…
Theories in reading instruction
TOP-DOWN READING MODEL
Emphasizes what the reader brings to the text
Says reading is driven by meaning
Proceeds from whole to part
Views from some researchers
1. Frank Smith – Reading is not decoding written language to spoken language
2. reading is a matter of bringing meaning to print
FEATURES OF TOP-DOWN APPROACH
Readers can comprehend a selection even though they do not recognize each word.
Readers should use meaning and grammatical cues to identify unrecognized words.
Reading for meaning is the primary objective of reading, rather than mastery of letters, letters/sound relationships and words.
FEATURES OF TOP-DOWN APPROACH
Reading requires the use of meaning activities than the mastery of series of word- recognition skills.
The primary focus of instruction should be the reading of sentences, paragraphs, and whole selections
The most important aspect about reading is the amount and kind of information gained through reading.
BOTTOM UP
Emphasizes a single direction
Emphasizes the written or printed texts
Part to whole model
Reading is driven by a process that results in meaning
PROPONENTS OF THE BOTTOM UP
Flesch 1955
Gough 1985
FEATURES OF BOTTOM-UP
Believes the reader needs to:
Identify letter features
Link these features to recognize letters
Combine letter to recognize spelling patterns
Link spelling patterns to recognize words
Proceed to sentence, paragraph, and text- level processing
INTERACTIVE READING MODEL
It recognizes the interaction of bottom-up and top-down processes simultaneously throughout the reading process.
Reading as an active process that depends on reader characteristics, the text, and the reading situation (Rumelhart, 1985)
Attempts to combine the valid insights of bottom-up and top-down models.
PROPONENTS OF THE INTERACTIVE READING MODEL
Rumelhart, D. 1985
Barr, Sadow, and Blachowicz 1990
Ruddell and Speaker 1985

software design is very crusial thing to manage therfore software 'software design is very crusial thing to manage therfore software software design is very crusial thing to manage therfore software software design is very crusial thing to manage therfore software
A bit of a retrospective. Back in the spring of 2005, I delivered this presentation at a Defense Software Symposium. The idea was that if we manage the knowledge behind a software system properly we can create, integrate, manage, and evolve that software far more effectively than we have in the past. This discussion proceeded with reference to very large and very complex software engineering and integration projects.
Chapter 7 Design Architecture and Methodology1.docxmccormicknadine86
Chapter 7:
Design: Architecture and Methodology
1
Design Topics Covered
Architectural vs. detailed design
“Common” architectural styles, tactics, and reference architectures
Basic techniques for detailed design
Basic issues with user-interface design
2
Design
Starts mostly from/with requirements (evolving mostly from functionalities and other non-functional characteristics).
How is the software solution going to be structured?
What are the main components—(functional comp)?
Often directly from requirements’ functionalities
(use cases).
How are these components related?
Possibly re-organize the components (composition/decomposition).
Two main levels of design:
Architectural (high level)
Detailed design
How should we depict design—notation/language?
3
Relationship between Architecture and Design
Detailed Design
Comes from
Requirements &
Architecture
4
Software Architecture
Structure(s) of the solution, comprising:
Major software elements
Their externally visible properties
Relationships among elements
Every software system has an architecture.
May have multiple structures!
Multiple ways of organizing elements, depending on the perspective
External properties of components (and modules)
Component (module) interfaces
Component (module) interactions, rather than internals of components and modules
5
Views and Viewpoints
View – representation of a system structure
4+1 views (by Krutchen)
Logical (OO decomposition – key abstractions)
Process (run-time, concurrency/distribution of functions)
Subsystem decomposition
Physical architecture
+1: use cases
Other classification (Bass, Clements, Kazman)
Module
Run-time
Allocation (mapping to development environment)
Different views for different people
6
Architectural Styles/Patterns
Pipes and filters
Event driven
Client-server
Model-view-controller (MVC)
Layered
Database centric
Three tier
We discuss architectural styles/patterns as
“reusable” starting point for design activities.
7
Pipe-Filter Architecture Style
The high-level design solution is decomposed into two “generic” parts (filters and pipes):
Filter is a service that transforms a stream of input data into a stream of output data.
Pipe is a mechanism or conduit through which the data flows from one filter to another.
Input
time cards
Prepare for
check processing
Process checks
Problems that require batch file processing seem to fit this architecture: e.g., payroll, compilers, month-end accounting.
** Reminds one of DFD without the data store or source sink.**
8
Event Driven (Real Time)
The high-level design solution is based on an event dispatcher, which manages events and the functionalities that depend on those events. These have the following characteristics:
Events may be a simple notification or may include associated data.
Events may be prioritized or be based on constraints such as time.
Events may require synchronous or asynchronous processing.
Events may be “registered” ...

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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).
