Big Data Management, Integration and Workflows

Increasingly, organizations seek to analyze the growing number of data available to develop actions that bring competitive advantage and prominence in their field of activity. This process ranges from the correct collection and storage of data to their integration with information obtained from the Web. The data are associated with the organization’s planning, management and performance, and can be structured, semi-structured and unstructured. Thus, there is a need for treatment, transforming them into information and knowledge.

In order to significantly assist this process, this project analyzes different research opportunities. First, the need to process large volumes of heterogeneous data in a parallel and distributed manner is highlighted. This is a typical scenario in large projects in different areas of knowledge, such as bioinformatics, astronomy, engineering and medicine, where workflows have been widely adopted. Many of these workflows are large-scale and require high-performance computing environments (such as clusters, supercomputers and computer clouds) and parallelism techniques to run it in a viable time. In addition to these environments, in recent years, there has been frequent use of large-scale data-centric computing frameworks (Data Intensive Scalable Computing), such as Apache Spark, which provides efficient memory processing. One of the objectives of this project is to develop workflows for large-scale data management and analysis using these frameworks and to optimize their execution in parallel and distributed environments. Finally, the objective is also to study conceptual modeling techniques with workflows and ontologies applied to Big Data, and pre-processing, indexing and querying in Big Data, including approaches based on distributed storage systems (HDFS), management systems of object-relational databases, NoSQL and newSQL.
