Detecting Functional Requirements Inconsistencies within Multi-teams Projects Framed into a Model-based Web Methodology

One of the most essential processes within the software project life cycle is the REP (Requirements Engineering Process) because it allows specifying the software product requirements. This specification should be as consistent as possible because it allows estimating in a suitable manner the effort required to obtain the final product. REP is complex in itself, but this complexity is greatly increased in big, distributed and heterogeneous projects with multiple analyst teams and high integration between functional modules. This paper presents an approach for the systematic conciliation of functional requirements in big projects dealing with a web model-based approach and how this approach may be implemented in the context of the NDT (Navigational Development Techniques): a web methodology. This paper also describes the empirical evaluation in the CALIPSOneo project by analyzing the improvements obtained with our approach.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015-71938-RED

SAMOS - A framework for model analytics and management

The increased popularity and adoption of model-* engineering paradigms, such as model-driven and model-based engineering, leads to an increase in the number of models, metamodels, model transformations and other related artifacts. This calls for automated techniques to analyze large collections of those artifacts to manage model-* ecosystems. SAMOS is a framework to address this challenge: it treats model-* artifacts as data, and applies various techniques—ranging from information retrieval to machine learning—to analyze those artifacts in a holistic, scalable and efficient way. Such analyses can help to understand and manage those ecosystems

Clone Detection in Matlab Stateflow Models

Matlab Simulink is one of the leading tools for model based software development in the automotive industry. One extension to Simulink is Stateflow, which allows the user to embed Statecharts as components in a Simulink Model. These state machines contain nested states, an action language that describes events, guards, conditions and actions and complex transitions. As Stateflow has become increasingly important in Simulink models for the automotive sector, we extend previous work on clone detection of Simulink models to Stateflow components

A Comparison Tool For Quality Software Requirement Specification

Most of the problems in software development come from a bad requirement specification. Failure on the requirements gathering phase is usually caused by unclear, ambiguous, inconsistent or incomplete requirements [1]. Thus, many researchers work on how to improve the quality of requirement specification. Even this is not the largest task of a project, it is really important to provide a flawless requirement specificatio

Investigation of SQL Clone on MVC-based Application

Model-View-Controller (MVC) design pattern is design pattern that is suitable for interactive systems. MVC is adapted in desktop and web-based applications. Moreover, many frameworks are adapting MVC pattern. Each layer of MVC has a different function. The main function of the model layer is query to the database system that represented by SQL language. In software development, code duplication or code clone is a serious problem because it will impact on the maintenance process. Associated with model layer and code clone, clone detection approach that exists today is not effective to detect clones in the model layer represented by SQL language, because the definition of code clone is not suitable for SQL clone.  SQL is declarative language that is different from the common programming language like C and Java. So, the definition of code clone must be adjusted with characteristic of SQL. In this research, we investigate the existence of SQL clone on MVC-based application and define the types of SQL clone. We define four types of SQL clone and they are confirmed exist in MVC-based application datasets that used in this researc
