En este trabajo se presenta una aplicación para evaluación y control de proyectos de software. La novedad de esta aplicac ión es que ha sido desarrollada usando un sistema gestor de bases de dat os extendido con lógica difusa. Además de las tareas habitua les de una herramienta de control de proyectos, esta aplicación pe rmite evaluar la gestión de...
The Project Challenges of the Fuzzy Relational Model , aim to solve open problems about the treatment of fuzzy data in relational databases. In the present work several results of this proje ct are reported. Some concern with Type 2 fuzzy attributes, w hich are based on probability distributions. Others are on Type 3 fuzzy dat a, based on similarit...
There are many different database management systems (DBMSs) on the market today. They all have different strengths and weaknesses. What if all of these different DBMSs could be used together in a heterogeneous network? The purpose of this thesis is to explore ways of connecting the many different DBMSs together. This thesis will explore suitable a...
[EN] The accessibility to services of web clinic is of utmost importance for success of any companies. Internet is a great way to make a clinic known to a large number of people that might potentially be interested in the services that the clinic might provide. Therefore, a creation of a website that would provide different information about the cl...

Understanding the thermal distribution within the crust and rheology of the earth’s lithosphere requires the knowledge of the Depth to the Bottom of Magnetic Sources (DBMS). This depth is an important parameter in this regard, which can be derived from aeromagnetic data and can be used as a representation for temperature at depth where heat flow va...

Databases are critical to all scientific endeavours. They manage our email, funding, and scientific literature, and provide access to the ever-growing mountains of scientific data. In molecular virology, all researchers are familiar with performing BLAST searches of the DNA and protein sequence databases; however, in some respects these are simple ...

This paper introduces an efficient distributed data analysis framework for big data which comprises data processing at the data collecting nodes and the central server end as opposed to the existing framework that only comprises data processing at the central server end. As data are being processed at the data collecting end in the proposed framewo...
External sorting algorithms are commonly used by data-centric applications to sort quantities of data that are larger than the main-memory. Many external sorting algorithms were proposed in state-of-the-art studies to take advantage of SSD performance properties to accelerate the sorting process. In this paper, we demonstrate that unfortunately, ma...
It can be difficult to choose the right NoSQL DBMS, and some systems lack sufficient research and evaluation. There are also tools for moving and transforming data between DBMS' in order to combine or use different systems for different use cases. We have described a use case, based on requirements related to the quality attributes Consistency, Sca...
