CMS stands for Content Management System. There are different types of CMS, usually, refers to Web CMS (WCMS) which is a software that allows common users to manage content of web pages without necessary knowledge from web developers or databases administrators. Project of the research program "Monitoring of Oil activities in Ecuador : a cross-disciplinary approach between Environment, Health and People" better known as Monoil, needs to publish information to internet, for example, data from agreements, associations, investigators résumé, investigations, news, etc. In the way we are thinking about web sites, all these data is treated as a “content”, then, Monoil needed a WCMS. Before solutions that were implemented, demanded certain performance and managers (of contents) were not agreed with them. Thus, the project decided to create CMS Monoil application which is a made-to-order Manager Content software. This solution includes CMS Monoil Application, destined to investigators and general public, and a Module for maintaining tables of CMS, for administrators who change frequently the content of the pages; these projects are included in the main solution Monoil as a built-in software. The CMS is developed with open source technologies such as Java platform with JSF Framework, Apache Tomcat web application and PostgreSQL database. In order to carry out this project with Software Engineering standards, SCRUM was selected as the agile methodology of developing, which through Sprints, created the CMS Monoil under these agile practices.
