Groupware systems are closely related with factors which define organization and knowledge of the group. Taking into account these factors are very variable, development and management processes of these systems are complex and need adaptable infrastructure which guarantees their correct evolution. From this need, we propose AGORA as a layered architecture for building flexible cooperative applica... View full abstract»

Data warehouses integrate several operational sources to provide a multidimensional analysis of data, thus improving the decision making process. Therefore, an in-depth analysis of these data sources is crucial for data warehouse development. Traditionally, this analysis has been based on a set of informal guidelines or heuristics to support the manually discovery of multidimensional elements on a... View full abstract»

This paper shows how model-driven software development (MDSD) can be applied in the bioinformatics field since biological data structures can be easily expressed by means of models. The existence of several heterogeneous data sources is usual in the bioinformatics context. In order to validate the information stored in these data sources, several formalisms and simulation tools have been adopted. ... View full abstract»

Similarity search has a growing usefulness in a range of applications like time series, image and multimedia databases, biological data, and so on. These searches are implemented by means of neighbour queries in the multidimensional spaces where the data resides. Faced with a large volume of data, it becomes imperative the use of indexing methods with specific algorithms capable of reducing the qu... View full abstract»

Business processes (BP) are an important resource in enterprise performance and in maintaining competitiveness. In the last few years, languages used for BP representation have been improved and new notations have appeared. The importance of security in BP is widely accepted. However, the perspective of the business analyst in relation to security has hardly been dealt with. In this paper, we pres... View full abstract»

Information systems supporting business processes can be improved by the use of Ubiquitous Computing (Ubicomp) technologies. However, the dynamism of business processes and the complexity in the construction of Ubicomp systems requires an adequate method for its development. This paper proposes a model driven development method to obtain this kind of systems in a systematic way, abstracting techno... View full abstract»

Generally, security and audit measures for Data Warehouses (DWs) are defined in the final implementation on top of commercial systems because there is not a standard for the exchange and the operability of metadata. The Common Warehouse Metamodel (CWM) proposal is broadly accepted as the standard for the interchange and the interoperability of metadata. Nevertheless, it does not allow us to specif...

Currently, in order to obtain high quality software products it is necessary to carry out a good software processes management in which measurement is a fundamental factor. Due to the great diversity of entities involved in software measurement, a consistent framework to integrate the different entities in the measurement process is required. In this paper the software measurement framework (SMF) ... View full abstract»
