The document discusses source control implementation goals for a large distributed PowerBuilder development project. It proposes a two-tiered archive structure with both file-level and object-level source control to address the needs of the PowerBuilder development model. A key part of the model is a "staircase methodology" involving development, unit testing, and other stages that allows for isolated environments and reliable releases while supporting the entire application lifecycle.
This presentation explains what is unit testing, why unit testing is important and gives a head start on how to implement unit testing in your .NET projects using NUnit test framework.

Revision control system which is also known as version control and source control.It is used for the Management of changes to documents, computer programs and other collection of information.
This document provides an overview of source code management and version control systems. It discusses traditional methods of saving code versions, introduces centralized and distributed version control systems, and covers common terms and processes used in version control like branching, committing, tagging, and logging. It also provides a high-level overview of using Git for version control tasks like initializing a repository, adding/committing code, branching, merging, and viewing logs or diffs of changes.
The document discusses use cases and scenarios in software engineering. It defines use cases as narratives that describe how users will interact with a system. Use case diagrams visualize relationships between actors and use cases. The document provides examples of use case diagrams and describes how to document use cases, including typical elements like actors, flows, and alternate flows. It provides guidance on writing effective use cases, such as defining goals and needs for each actor.
Code Generation 2014 - ALF, the Standard Programming Language for UMLJürgen Mutschall
Presentation at the Code Generation 2014 conference at Cambridge.
The Action Language for Foundational UML (ALF) is a standard domain modeling and programming language for the executable (foundational) subset of standard UML (fUML). ALF is used for specifying executable behaviors within an overall graphical UML model.
This document describes the ReORe process for assessing whether to reuse or rewrite an existing system. ReORe leverages existing code, requirements, and technologies to reduce assessment costs. It applies textual, static, and dynamic analyses in 5 steps of increasing expertise to map requirements to existing code entities. A case study applying ReORe to a browser found it effectively reduced manual effort while identifying code that could be reused to implement some requirements.
Model Driven Architecture and eXecutable UMLelliando dias
The document discusses Model Driven Architecture (MDA) and how executable UML models can support MDA. Key points include:
- MDA uses three primary model viewpoints: computation independent, platform independent, and platform specific models.
- Executable UML models can be used to validate platform independent models by executing acceptance tests on them.
- Model transformations allow automated mappings between models and generation of platform specific models.
Version control systems (VCS) allow developers to manage code through capabilities like reversibility, concurrency, and annotation. Subversion is a popular centralized VCS that was released in 2000. It uses a trunk-branch-tag structure where the trunk contains stable code, branches are for development work, and tags create snapshots. Developers check code out from the repository, check changes in after making modifications, and view file histories.
The document discusses object modeling for software engineering projects. It covers modeling reality versus models, the types of objects (entity, boundary, control), and the order of activities in object modeling. The key activities in object modeling include identifying classes from use cases, flows of events, and other documentation. Class diagrams are then generated to represent the relationships between these classes.

Other types of software testing are as shown.
Software (requirement) analysis using umlDhiraj Shetty

Personas, Scenarios, User Stories, Use Cases (IxDworks.com)Valeria Gasik
This document discusses user-centered design approaches like personas, scenarios, and user stories. It provides templates and examples for creating a persona profile with background, goals, and mapping. Scenarios are described as stories that illustrate user interactions and goals. User stories are goals the user wants to accomplish with the product in a simple format, while use cases describe step-by-step processes. The document advises creating these artifacts based on research to understand users and explore design solutions from their perspective.

Software engineering Questions and AnswersBala Ganesh
1. Risk management is the process of identifying, addressing, and eliminating potential problems that could threaten the success of a project before they cause damage. This includes issues that could impact cost, schedule, technical success, product quality, or team morale.
2. HIPO (Hierarchical Input Process Output) diagrams were developed at IBM as a design representation and documentation aid. They contain a visual table of contents, overview diagrams, and detailed diagrams.
3. Software maintenance is any work done to modify software after it is operational, such as fixing errors, adding capabilities, removing obsolete code, or optimizing performance. It aims to preserve the software's value over time as requirements, users, and technology change. M
The document discusses various types of UML diagrams including use case diagrams, class diagrams, interaction diagrams (sequence and collaboration diagrams), state diagrams, and activity diagrams. It provides details on when each diagram should be used and includes examples to illustrate how to draw each type of diagram. The key points covered are that UML diagrams allow viewing a software system from different perspectives and varying degrees of abstraction, and each diagram type has a specific purpose to model different aspects of a system.
