Uso de los modelos tradicionales y las metodologías ágiles aplicadas en la industria de software colombiano
(Universidad Santiago de Cali, 2019) Ortega Galíndez, Manuel Alejandro; Camacho Ramirez, Edgar David; Ospina López, Orlando
The world of computer technology has been constantly evolving in terms of the design of its projects. Thanks to the "boom" of the internet, the demand for applications in all sectors of the industry has increased. Today we talk about traditional models and agile methodologies as development bases applied in projects, with their advantages and disadvantages. Traditional models are based on the first existing development models in the technological field. They opt for the paradigm of a fundamental a priori, analysis that guarantees enriched development and manage to close the gap of problems and complications that may arise during the development stage, ultimately decreasing time and resources. Moreover, agile methodologies propose a flexible form of work, whose planning is continuously updated, being its main objective to get the software up and running as soon as possible. Correctly defining the methodology to be implemented in a new project can be the long-term livelihood of an application's success or failure. Each methodology has its orientation, correctly defining and validating this can take a good time out of the total pre-implementation planning of a project, but it is necessary because this will eventually even define the profitability of it. This monographic article provide an overview of the use of some development models and methodologies and their use at the Colombian level, based on some of the most representative models of traditional approach as well as agile methodologies.

Xamarin: La propuesta de Microsoft para el desarrollo móvil multiplataforma
(Universidad Santiago de Cali, 2019-11-15) Pantoja Mosquera, Luis Carlos; Dinas, Simena
The development of mobile applications implies the need for them to be encoded in different operating systems, resolving different technical and technological difficulties so that the APPS work in a single environment of business information and are executed in each of the existing operating systems in the market. Developing mobile applications using the tools of each operating system means investing more time and greater costs, in addition to not responding quickly to the needs of the market, which jeopardizes the objectives of the companies, by not being able to place the APP early to users to run on all operating systems. To solve the above difficulties, today developers have multiplatform mobile development tools that allow the coding of the APP in different operating systems. The objective of this article is to show how Xamarin technology, acquired at the beginning of 2016 by Microsoft, is a good alternative for multiplatform development of mobile applications specifically for Android, iOS and Windows operating systems. The article contains a description of Xamarin's cross-platform features, installation requirements, aspects such as the development environment, the test environment, the implementation environment and the visual design environment among others.
