SECURE DESCARTES: A SECURITY EXTENSION TO DESCARTES SPECIFICATION LANGUAGE
With increase in demand for the security aspects of software, every phase of the Software Development Life Cycle (SDLC) is experiencing major changes with respect to security. Security designers, developers, and testers are keen on improving various security aspects of a system. Specification of security requirements propagates to different phases of an SDLC and there exist different techniques and methodologies to specify security requirements. Business level security requirements are specified using policy specification languages. The current literature has specification languages that are domain based, web based, network based, syntax based, semantics based, predicate based, and protocol based. In this research effort, a
generic secure policy prototype and components of the generic secure policy were defined using formal methods. The Descartes specification language, a formal executable specification language, has been developed to specify software systems. The development of a secure policy framework along with extended constructs of the Descartes specification language for specifying secure policies are some of the deliverables of this research effort. Concepts of secure policies were adopted from the SPromela, Ponder, and REI methodologies for secure policy specification, analysis, and design.
50120140503001
This document compares model-oriented and process algebra approaches to formal specification languages. It discusses key formal specification styles including model-oriented, algebraic, transition-based, process algebra, logic-based, and reactive approaches. It then evaluates several model-oriented (Z, VDM, B) and process algebra (CSP, CCS) languages based on criteria like abstraction, ambiguity, consistency, concurrency, readability and reusability. Finally, it discusses the B method and its tool support, comparing it to related techniques like Event-B, VDM, TLA, ASM and Z. The document provides an overview of different formal specification approaches and evaluates some example languages in these categories.

journal of object technology - context oriented programming
This document introduces Context-oriented Programming (COP) as a new programming technique to enable context-dependent computation. COP treats context explicitly and provides mechanisms to dynamically adapt behavior in reaction to context changes at runtime. The document discusses the motivation for COP, defines context and how it can influence behavior, and provides examples of COP implementations in different programming languages. COP aims to bring the same degree of dynamicity to behavioral variations as object-oriented programming brought to polymorphism.
Design Pattern
This document discusses design patterns, including their definition, elements, and relationship to frameworks. It provides an overview of design patterns, describing them as general and reusable solutions to common software problems. The document outlines the core elements of patterns, such as their name, problem, context, solution, and examples. It also discusses different categories of patterns, such as creational, structural, and behavioral patterns.

10.1.1.92.7063
This document proposes a method called "diverse firewall design" to address challenges in correctly designing firewall policies. The method has three phases: 1) a design phase where multiple teams independently design firewall policies based on the same requirements, 2) a comparison phase where the designs are compared to detect differences, and 3) a resolution phase where the differences are resolved to generate an agreed-upon firewall policy. The document focuses on algorithms to efficiently discover all functional differences between two firewall policies, which can also be used to analyze the impact of changes to a firewall policy.

A neural conversational_model
This paper proposes a neural conversational model that uses a sequence-to-sequence framework to generate answers to questions. It can be trained end-to-end without many hand-crafted rules and can generate simple conversations given large training data. The model adopts the sequence-to-sequence framework and is trained using backpropagation to maximize cross entropy. During inference it uses greedy decoding but beam search could also be used. The model was verified by having humans rate it against CleverBot on 200 questions and it can generate basic conversations and answer questions without rules.
Neural machine translation by jointly learning to align and translate
This paper proposes a neural machine translation model that extends previous work by incorporating an attention mechanism, allowing the decoder to soft-search relevant parts of the input without explicitly segmenting it. The bidirectional RNN architecture with attention outperforms earlier encoder-decoder models on English-to-French translation tasks according to BLEU scores, handling variable length inputs more effectively. While promising, the model could be improved to better handle rare or unknown words.
Refactoring for Software Design Smells
Awareness of design smells - indicators of common design problems - helps developers or software engineers understand mistakes made while designing and apply design principles for creating high-quality designs. This presentation provides insights gained from performing refactoring in real-world projects to improve refactoring and reduce the time and costs of managing software projects.
Ch 5 O O Data Modeling Class

Layered architecture style
This document discusses architectural styles and describes the layered pattern. It defines architectural styles as descriptions of component and connector types that constrain how they relate. The layered pattern organizes a system into hierarchical layers, with each layer providing services to the layer above and acting as a client to the layer below. Advantages include independence of layers, reusability, flexibility and maintainability, while disadvantages include potential performance issues with too many layers. Examples given include operating systems and virtual machines.
Three Software Architecture Styles
The three common software architecture styles commonly used in distributed systems and XML Web Services are compared and contrasted. In particular, the key differences between traditional SOAP and REST styles are explored. Guidelines are presented on which style is most applicable for certain application scenarios, and when a combination of styles is necessary.
07 software connectors
Software connectors are architectural elements that model interactions between components. They define rules governing interactions and provide channels for transferring control and data. In software systems, connectors are often not explicitly implemented but distributed across code, while in architectures they are first-class entities with identities. Treating connectors independently from components supports separation of interaction from computation and facilitates software evolution.
13 analysis of_software_architectures
Architectural analysis involves discovering important system properties using architectural models. It is important to conduct analysis early using informal models to get stakeholder clarification and ensure project scope, while more formal models help with implementation decisions, component selection, and code generation. Architectural analysis aims to evaluate completeness, consistency, compatibility, and correctness. It considers various concerns like structural elements, data flow, interaction, and non-functional properties at different levels of the system.
07 software connectors (2)
The document discusses software connectors, which are architectural elements that model interactions between components. Connectors provide interaction ducts to transfer control and data between components. While connectors may be distributed across code modules in implementations, they are first-class entities in software architectures with their own specifications and abstractions. Treating connectors as independent elements separates computation from interaction and provides benefits such as flexibility, evolution, and analysis of systems. The document outlines different roles and types of connectors.
20 nfp design_techniques
The document discusses techniques for managing complexity, scalability, adaptability, and dependability in software architecture and design. It recommends separating concerns into independent components with well-defined interfaces, using explicit connectors to define and restrict interactions, avoiding unnecessary dependencies, and employing architectural styles and configurations that support qualities like distribution, parallelism, and avoidance of bottlenecks.

Simon Brown: Software Architecture as Code at I T.A.K.E. Unconference 2015
This document discusses software architecture and how it relates to code. It suggests that software architecture should be more accessible to developers and embodied in the code through architecturally evident coding styles. Components can be extracted from code if naming conventions, packaging, and other patterns are used. Both diagrams and code should reflect the architectural abstractions. Software architecture models can be maintained as code to keep them in sync with implementation changes.
05 architectural styles
The document discusses several common software architectural styles, including:
1) Object-oriented style where components are objects that communicate via messages and method invocations.
2) Layered style which uses a hierarchical organization with each layer acting as a client or server to adjacent layers.
3) Client-server style where servers provide services to clients without knowing their identities or numbers.
4) Data-flow styles like pipe and filter where components are independent filters that transform input data streams.
Cbt component based technology architectures
This document discusses various component models and technologies, including ACME, Java Beans, COM/DCOM/MTS, CORBA, .NET, and OSGi. It covers topics such as component interfaces, connections, interactions, lifecycles, architectures, and specific models like Java Beans. The Java Bean component model is described in more detail, including its key features around reusable software components, interfaces focusing on methods, properties, events, and implementations as simple Java objects or more complex wrappers.

Cs 1023 lec 6 architecture (week 1)
The document describes several common architectural styles, including object-oriented, layered, client-server, data-flow, blackboard, mobile code, implicit invocation, publish-subscribe, event-based, peer-to-peer, and heterogeneous styles. For each style, the document outlines the typical components, connectors, topology, advantages, and disadvantages. It also provides examples and line diagrams to illustrate how each style can be implemented.
DDD
Domain-driven design (DDD) is an approach that involves using a shared domain model and ubiquitous language to support complex domains and ensure alignment between software design and business needs. It emphasizes basing the software design on an evolving model that shares common concepts with domain experts. DDD uses patterns like entities, value objects, aggregates and repositories to structure the software around domain concepts and separate domain logic from data access and external interfaces.
Put Your Hands in the Mud: What Technique, Why, and How
The document discusses techniques for analyzing unstructured text data from software repositories. It describes using textual analysis on code identifiers, comments, commit messages, issue trackers, emails, and forums to perform tasks like traceability link recovery, feature location, clone detection, and bug prediction. Different techniques are discussed, including pattern matching, island parsers, information retrieval methods, and natural language parsing. Choosing the right technique depends on the type of unstructured data and needs of the analysis.
CASE tools and their effects on software quality
CASE tools can significantly improve software quality by automating tasks, reducing errors, and standardizing development processes. They provide functionality for data modeling, code generation, refactoring, documentation and more. While some aspects like requirements gathering require human input, overall CASE tools improve design, catch issues early, and allow developers to focus on other important work. Proper use of modeling languages and automation can dramatically enhance software quality across all stages of development.
06 styles and_greenfield_design
The document discusses several techniques for developing software architectures when no existing architecture exists to build upon. It describes strategies like analogy searching, brainstorming, literature searching, and morphological charts that can be used to generate novel ideas for the architecture. It also emphasizes controlling the design strategy through techniques like identifying critical decisions, relating costs to risks, and continually re-evaluating requirements and implementation constraints.
Interoperability
This document discusses interoperability between software components. It defines interoperability as the ability of independently developed components to interact meaningfully by communicating and exchanging data or services. Achieving interoperability is challenging due to heterogeneity between components in terms of programming languages, platforms, data formats, and assumptions. Common Object Request Broker Architecture (CORBA) and XML are examined as approaches to enabling interoperability, but both make assumptions that can limit their effectiveness and even introduce new interoperability issues in some cases. Shaw's taxonomy of interoperability solutions is also referenced.
03 basic concepts
Software architecture is the set of principal design decisions about a software system. It includes decisions about the system's structure, behavior, and interactions. Principal design decisions are those that have a significant impact on the system and are important to stakeholders. A software system's architecture can change over time as design decisions are made and remade throughout the system's lifetime.

Key practices of XP are outlined, including user stories, testing, pair programming, refactoring, and continuous integration. The role of architecture in agile processes is also addressed.
7 - Architetture Software - Software product line
This document discusses software product lines and product line architectures. It defines a software product line as a set of software systems that share a common set of features addressing a particular market segment. Product lines are developed from a common set of core assets in a prescribed way to reduce costs and increase reuse. A product line architecture is a common framework that standardizes components and maximizes reuse potential. It specifies common functionality and identifies variation points across related products. Variability management is important for providing flexibility without compromising commonality.
6 - Architetture Software - Model transformation
This document discusses model transformations in Model-Driven Architecture (MDA). It defines computation independent models (CIMs), platform independent models (PIMs), and platform specific models (PSMs). It explains that model transformations are used to map between these different abstraction levels and ensure consistency. It also discusses model mappings, approaches to transformations, and tools like EMF and ATL that support transformations in Eclipse.
5 - Architetture Software - Metamodelling and the Model Driven Architecture
The document discusses metamodeling and the Model Driven Architecture (MDA). It covers topics such as model driven engineering, metamodeling, metamodeling in UML, and the OMG technologies that support MDA. Metamodeling involves modeling modeling elements and their relationships. Metamodels define the structure of models, while models are instances that conform to metamodels. The MDA uses metamodels and models to develop and transform systems.
4 - Architetture Software - Architecture Portfolio
This document provides an overview of software architectures by presenting examples of architectures from various software systems. It begins with an introduction to software architecture and what it entails. It then shows numerous diagrams and visualizations of architectures for different types of systems, such as editors, compilers, operating systems, middleware, and web applications. These examples are intended to demonstrate common architectural patterns and styles. The document discusses analyzing and comparing the architectures visually and recognizing patterns within them.
3 - Architetture Software - Architectural styles
The document discusses architectural styles and decomposition techniques for software systems. It describes layering and tiering as basic decomposition approaches, with layers representing different levels of abstraction and tiers representing peer modules within the same layer. Several common architectural styles are then introduced, including pipes and filters, repository, client/server, model-view-controller, service-oriented, and peer-to-peer. Closed and open layered architectures are contrasted, and examples of layered systems like virtual machines and the OSI model are provided. Finally, the document notes that complete decompositions often involve both layering and partitioning techniques.
2 - Architetture Software - Software architecture
The document discusses key concepts in software architecture, including:
1) Software architecture establishes the overall structure and organization of a system, including its components and relationships.
2) Architectural design involves decomposing a system into subsystems or modules to improve modifiability, reusability, and portability.
3) Key principles for architectural design include simplicity, modularity, low coupling, separation of concerns, abstraction, and postponing decisions.
1 - Architetture Software - Software as a product
This document discusses software as a product and industry. It covers how software is a key component in modern technologies and industries. The software industry has grown significantly in recent decades. The document discusses different types of software such as embedded software, middleware, and software as a service. It also covers topics like software architecture, engineering, components, ecosystems, and the challenges in developing software. Overall, the document provides an overview of software as an industrial product and the software development industry.
10 - Architetture Software - More architectural styles
The Microkernel pattern partitions an operating system into isolated, minimal components that communicate through a small, fixed message-passing interface, allowing components to be developed and upgraded independently while maintaining overall system stability and security.
Uml3
The document discusses architectural UML and provides information on:
1) The elements of a software architecture including views, models, and diagrams.
2) How UML can be used to represent different architectural views including design, process, development, and physical views.
3) An example of using UML models and diagrams to represent different views of a chess game architecture.
Uml2
UML allows for extending diagrams and modeling elements through three main techniques:
1. Stereotypes allow applying tags to existing modeling elements like classes, associations, etc. to add domain-specific meaning.
2. Profiles extend UML with new modeling elements tailored for specific domains or platforms.
3. Extension mechanisms allow precisely defining new constructs that integrate with the UML metamodel. Together these techniques make UML extensible for multiple domains.

The document discusses metamodeling and the Model Driven Architecture (MDA). It provides an overview of model driven engineering and metamodeling. Specifically, it discusses how metamodels define the structure of models through concepts like classes and relationships. The Model Driven Architecture uses metamodels and modeling to develop software systems from models.
4 (uml basic)
Here are the key differences between objects and classes in UML:
- Classes define the general characteristics (attributes and operations) that objects of that class will have. Objects are specific instances of a class.
- Classes are static definitions, while objects are dynamic instances of classes that exist at run time.
- In class diagrams, classes are represented as boxes containing the attributes and operations. Objects are represented as boxes with the class name followed by a colon and the object name (e.g. Person:John).
- Classes define the common properties for a set of objects, while each object is a unique instance of a class with its own identity and particular values for attributes.
- Classes are abstractions,

The document discusses architectural styles and decomposition techniques. It describes layers as hierarchical sets of subsystems that provide related services by utilizing underlying layers. Tiers partition a system into peer subsystems responsible for classes of services. Common architectural styles include pipes and filters, repository, client/server, model-view-controller, service-oriented, and peer-to-peer. Layers and tiers are often combined for complete decomposition, with subsystems divided into tiers and each tier organized into layers. The pipe and filter style focuses on dynamic interaction by processing data streams through filters connected by pipes.
