This work presents the HyperCAL 3D, an application to support the teaching and learning process of Descriptive Geometry through the study of solid objects. The methodology used for its implementation and the main features of the application are described. A selection of concepts was carried out to determine the functional structure of the software should have. From this, the main features were modeled through processes of vector geometry equivalent to that used in Descriptive Geometry. The main features introduced include the projection process, the representation of hidden lines in the three-dimensional model and the projections, successive auxiliary views in real time, and the intersection process. All these tools are implemented in an application that aids the learning process of the students and the teaching procedures of professors.

This paper discusses an automated approach to database change management throughout the companies’ development workflow. By using automated tools, companies can avoid common issues related to manual database deployments. This work was motivated by analyzing usual problems within organizations, mostly originated from manual interventions that may result in systems disruptions and production incidents. In addition to practices of continuous integration and continuous delivery, the current paper describes a case study in which a suggested pipeline is implemented in order to reduce the deployment times and decrease incidents due to ineffective data controlling.
