A multi-dimensional model for the design and development of analytical informat...
Santos, Maribel Yasmina; León, AnaThe design and development of Analytical Information Systems demand efficient techniques and technologies for processing vast amounts of data that arrive at high velocity or that are available in legacy/operational systems. While many advances have been verified in the technological field to deal with the potential volume, velocity, and variety of the data, fewer contributions can be found in the methodological...
A model-driven approach to enhance data visualization through domain knowledge ...
Almeida, Andreia; Alves, Alberto; Santos, Maribel Yasmina; León, Ana; Pires, João MouraBig Data is challenging analytical contexts, namely when aligning data and analytical requirements. While the capacity to collect and store new data is expanding rapidly, the pace at which it can be analyzed is developing more slowly. Defining these analytical requirements and selecting the most appropriate visualizations often depends on an in-depth understanding of what users need from the data. To address th...
Model-to-model transformation: from UML class diagrams to labeled property graphs
León, Ana; Santos, Maribel Yasmina; García, Alberto; Casamayor, Juan Carlos; Pastor, OscarConceptual schemas are the basis to build well-grounded Information Systems, by representing the main concepts of a domain of knowledge, as well as the relationships among them. Since conceptual schemas focus on the concepts, they are independent of the specific technological platform used to implement them. This allows a single conceptual schema to be transformed into different platform-specific models accordi...
M2M mapping and transformation tool for labeled property graphs
Guimarães, Pedro; León, Ana; Santos, Maribel YasminaClass Diagrams and Labeled Property Graphs are essential concepts in software development and are often used together in Model Driven Development approaches. This paper follows up on our previous work [1] that presented a new approach to transform models based on the analytical requirements. Nevertheless, these transformations can be complex and time-consuming when not supported by any tool. This follow-up pape...
An automated patterns-based model-to-model mapping and transformation system fo...
Guimarães, Pedro; León, Ana; Santos, Maribel YasminaDue to the increasing collection of highly interconnected and complex datasets, Labeled Property Graphs are gaining importance in extracting meaningful information for decision support. In addition, UML Class Diagrams are still a commonly used modeling technique for representing the main concepts of a domain. Although there are several model-to-model transformation approaches, these are mainly focused on moving...
Towards a model-driven approach for big data analytics in the genomics Field
Fernandes, Ana Xavier Silva Gomes; Ferreira, Filipa; León, Ana; Santos, Maribel YasminaThe use of techniques such as Next Generation Sequencing has allowed a fast increase in data generation due to the reduction of processing costs. What at the beginning seemed to be an important step forward for the development of new approaches such as Precision Medicine, turned into an exponential growth of data that currently challenges healthcare professionals and researchers. Since the problems derived from...
