This chapter introduces an object-oriented methodology for Geographical Information Systems (GIS) development. It argues that a COTS-based development methodology combined with the UML, can be extended to support the spatiotemporal peculiarities that characterize GIS applications. The author hopes that by typifying both enterprises and developments, and, with a thorough knowledge of the software component granularity in the GIS domain, it will be possible to extend and adapt the proposed COTS-based methodologies to cover the full lifecycle. Moreover, some recommendations are outlined to translate the methodology to the commercial iCASE Rational Suite Enterprise and its relationships with tool kits proposed by some GIS COTS vendors.

En la actualidad los sistemas de información tienen dificultades para conseguir el éxito deseado, debido que una de los sus componentes que es el desarrollo de aplicación web tienen dificultades para ser ejecutado, esto es debido que se requiere un tiempo para la creación de la programación y otro tiempo por separado para la creación del modelo de datos, no existe una técnica que integre ambos aspectos. Estudios recientes ha demostrado que existen varias técnicas de programación tales como programación orientación a objetos, programación orientada a aspectos y programación orientado agentes, y en la creación del modelo de datos también existen técnicas tales como base de datos orientado a objetos y entidad relación, El presente trabajo de investigación tiene como objetivo formular una técnica de desarrollo web basada en modelado de base de datos orientado a objeto haciendo uso de un modelo entidad relación. En consecuencia este estudio propone dos medidas para validar el rendimiento del desarrollo de aplicación web, empleando el análisis de varianza ANOVA, primero la cantidad de líneas de programas creados y el segundo tiempo de respuesta de la base de datos, dirigido a grupo de estudiantes del curso de programación web de la Escuela de Ingeniería de Sistemas de la Universidad Nacional de Ingeniera UNI. Con los resultados obtenidos se espera alcanzar, que los profesionales de software tengan un medio para reforzar sus conocimientos en el desarrollo de aplicación web, así mismo que los proyectos de sistemas de información en la etapa de desarrollo de la programación, tenga el éxito deseado. Palabras clave.- Técnica Programación, Datos Programación Orientado Objeto, Clase Entidad, Modelo de Datos. ABSTRACT Nowadays information systems are struggling to achieve the desired success, because one of its components is the development of web application struggle to be done, this is it because it takes a while for the creation of programming and once separately to create the data model, there is no technique that integrates both. Recent studies have shown that there are several programming techniques such as object oriented programming, aspect‐ oriented programming and programming targeted agents, and the creation of the data model are also techniques such as database connection object‐oriented entity, The this research aims to develop a web development technique based on database modeling object‐oriented model using entity relationship. Consequently, this study proposes two measures to validate the performance of web application development using analysis of variance, first the number of lines of programs created and the second response time database, led a group of students of the course web programming of the School of Universidad Nacional de Ingeniera UNI. The results obtained are expected to reach that software professionals have a means to strengthen their knowledge in the development of web application, likewise that information systems projects in the development stage of programming, has the desired success. Keywords.- Technique Programming, Web, Model of Object Oriented Data, Entities..

This research project gathered data about the use of UML and object-oriented analysis and design as the approach to the development of information systems. The data collection method consisted of interviews with information systems application developers with wide ranging differences in background. The authors used causal mapping for analysis of the data gathered. This chapter focuses on the authors’ experiences with causal mapping as a method for exploring issues and relationships. Causal mapping was also used to document tips on its use illustrating these with findings regarding UML and object-oriented analysis and design in particular.

In industrial practice, cloud computing is becoming increasingly established as an option for formulating cost-efficient and needs-oriented information systems. Despite the increasing acceptance of cloud computing within the industry, many fundamental questions remain unanswered, or are answered only partially. Besides issues relating to the best architectures, legal issues, and pricing models, suppliers of cloud-based solutions are faced with the issue of appropriate requirements engineering. This means eliciting optimal understanding of the customer’s requirements and implementing this into appropriate requirements of the solution to be realised. This chapter examines selected, established requirements engineering methods in order to study the extent to which they can be applied to the specific requirements of cloud-based solutions. Furthermore, it develops a comparison framework containing the features of cloud computing. This comparison framework is applied to four established process models for requirements engineering. Recommendations for a requirements engineering process adapted to cloud computing are derived.
