UML Software Analysis and System Design Principles

Software Analysis and System Design Principles

Analysis: Refers to the research and study of the problem.

Design: The study of the proposed solution.

Analysis and Design with UML

Using UML (Unified Modeling Language) can become somewhat subjective. The UML notation will lead the way for analysts, but the development of the diagrams is essential.

Visual Modeling and Construction

Preview: This is the visual model that facilitates communication and ensures the members of a group have the same idea of the design.

Construction: Automatic code generation from visual models.

Architectural Description: Provides a way to draw the plans and architecture of a system to include.

The Importance of Modeling

Reasons for Models: We want to communicate the structure of a system and provide an architectural view of a system.

UML Structure and Behavioral Diagrams

Structure Diagram: Visualization is used to build and document the static aspects of a system: classes, objects, components, installation, and packages that have been structured.

Behavioral Chart: This is used to specify, view, constitute, and document the dynamic aspects of a system, including use cases, state transitions, and activities.

Interaction Diagram: These are used for modeling the dynamic aspects of the system and show how objects interact to accomplish a task specified by a use case.

Model-Driven Methodologies (MDD and MDA)

MDD (Model-Driven Development): In this way, most of the effort is placed over the model; it is no longer just on source code. Software code is generated from the models, whether generating source code or not.

MDA (Model-Driven Architecture): Contemplates the standardization of specifications and operating system-independent technology based on the use of formal models.

Formal Language: The objective is to allow a notation that is easily understood by all involved in the business, including analysts, developers, and technicians, and finally by the managers.

Component Specifications and Interfaces

Component Diagram: Captures the physical structure of the implementation as a constituent part of the specification of the architecture, objects, developers, and programmers.

Component: It is a physical part of the bits and bytes of a replaceable system that provides the realization of a set of interfaces, such as different environments for development and production testing.

Interface: These are a set of operations used to specify the services of a class or components.

Operations: These are processes that a class can take; methods in a class correspond to public methods and
