"Clinical Decision Support Systems can alert health professionals about drug interactions when they prescribe medications. The Hospital Italiano de Buenos Aires in Argentina developed an electronic health record with dru...

Requirements Engineering is the key issue for the development of Software Systems, that meet the expectations of their customers and users, are delivered on time, and are developed within budget. This book intends to pr...

A book that describes and applies Software Engineering methods according to the state of the art of the subject matter; it is integrated with a proper exemplification and evolves as each topic is introduced. The material...

The concept of System Analysis was very common in the early stages of information systems. Different approaches to System Analysis share the goal of learning about the current system to establish the basis of the new sys...

Systems development methodologies continue to be a central area of research in software engineering. As the nature of applications and systems usage move increasingly towards open networked environments, not only are new...

I have been teaching, in reality, preaching, the importance of a clear understanding for the word “analysis”. It is my conclusion, after years of exposure to the term “system analysis”, that it has mislead lots o...

The motivation of this work comes from a Global Climate Model (GCM) Software which was in great need of being updated. This software was implemented by scientists in the ’80s as a result of meteorological research. Wri...

In this research a system, referred to as Jubair-Khaireddin (JK), has been developed to assess the degree of similarity between two programs even though they look superficially dissimilar. The JK system has the capabilit...

At present, the early phase of Requirements Engineering is a new research area in the Software Engineering field. This phase is concerned with the analysis of the organizational context in which a software system will be...

The present thesis describes a Requirements Engineering strategy, called SDRES (Scenario Driven Requirements Engineering Strategy), which proposes to face topics rarely treated in real practice, such as continuous change...

Many methodologies have been proposed to systematize the software development process. Many of them have been widely adopted. However, the majority has focused on analysis and design. Requirements have frequently been fo...

Any system interacting with a data base requires modules capable of operating data stored in it. Its development times generally vary between 50 to 60 % of the time used for the application life cycle. The present paper ...

Applying design patterns is considered a helpful technique for designing software systems. Patterns description, however, results not sufficiently precise providing a weak understanding and making it difficult to be cert...

Understanding how a user interacts with a system is important if the goal is to deliver a product that meets the user's needs. Use cases constitute a primary source of requirements in a user-centered perspective and are ...
