Design Modelling 1 Lecture 6

Data design creates a model of data or information at a high level of abstraction. It is refined into progressively more implementation-specific representations for processing by the system.

The data model is a high-level representation of data or information. It represents the relationships and structure of data within a system.

Data structures are specific ways data is organized within a program. These structures determine how data is stored and accessed.

The architectural model defines the high-level structure of a software system. It uses information from the application domain, requirements model, and architectural patterns.

Architectural patterns are reusable solutions to common problems in software design. They guide the architect in choosing the best structure and components for a system.

The central part of a system or program, responsible for controlling overall operation.

Provides a user-friendly interface for interacting with the system.

Processes commands and manages the system's state.

Detects events such as intrusion or fire.

Responds to detected events, e.g., by triggering an alarm.

Connects the system to external communication networks.

Provides management functions for the security system.

Ensures the security system is reliable and functional.

Evaluating the software architecture's ability to meet quality requirements and identifying potential risks.

Early detection of design problems in software architecture can significantly reduce project costs.

Economic, visible, spaced, symmetric, and emergent are key considerations in software architecture design.

Economy in software architecture focuses on keeping the design simple and using abstraction to cut down on unnecessary details.

Good architectural decisions should be clear and understandable to future engineers.

Separation of concerns in software design ensures that different aspects of the system are well-defined and don't depend on each other unnecessarily.

Architectural symmetry means a system has consistent and balanced attributes, making it easier to understand and maintain.

Emergent behavior in software emerges from interactions within a system and can be difficult to predict.

A set of operations that defines how a class interacts with the outside world, including its public operations.

The visual elements that a user interacts with when using a software application.

The way a software system interacts with other systems or components outside of its own code.

The communication mechanisms and data exchange protocols between different components within a software system.

A visual representation of interactions between objects and their methods, often used to model interfaces.

A specific type of communication diagram in UML, showing how objects collaborate to achieve a task.

Allows a software component to send and receive data wirelessly.

Provides access to and control over user input.

A style of architecture that focuses on data, with components performing operations on a central data store.

A style where data flows through a series of processing steps, with each step transforming the data in some way.

A style characterized by a hierarchical structure, with components calling on other components to perform tasks.

A style that uses objects as building blocks, with each object encapsulating data and methods to operate on that data.

A style that organizes components in layers, with each layer responsible for a specific aspect of the system.

A set of conventions and guidelines that define the structure, behavior, and interaction of components within a software system.

Components are independent units that encapsulate data and operations.

Connectors allow components to communicate and collaborate.

It is a representation of the software, showing how it is designed and constructed. It translates the analysis model into a design that is ready for development.

It focuses on organizing the software system into smaller, reusable modules or components. It outlines the overall structure of the software and how different parts interact.

It defines the data structures and classes that will be used in the software. It emphasizes representing information effectively and efficiently.

It deals with how the software interacts with other systems or users. It ensures that communication between different parts of the system is clear and consistent.

It focuses on the detailed design of individual software components. It specifies how each component will function and interact with others.

It is a representation of the software, showing how it is designed and constructed. It translates the analysis model into a design that is ready for development.

It focuses on the overall structure of the software and how different parts interact. It's like creating a blueprint for the entire system.

It defines the data structures and classes that will be used in the software. It emphasizes representing information effectively and efficiently.

It deals with how the software interacts with other systems or users. It ensures that communication between different parts of the system is clear and consistent. It is like designing the user interface of a website.

It focuses on the detailed design of individual software components. It specifies how each component will function and interact with others.

The Design Model is a representation of how the software is designed and constructed. It translates the analysis model, which focuses on understanding the problem, into a design that is ready for development.

The design model is built upon the analysis model and uses various representations like class diagrams, use-case diagrams, and collaboration diagrams to illustrate the software's structure and functionality.

The Design Model helps to create a comprehensive understanding of the software's structure and functionality. It aids in the development of software that is easy to understand, modify, and maintain.

The design model includes data/class design, architectural design, interface design, and component-level design. These elements work together to represent the software's structure, data representation, interactions, and components.
