The notion of an "Information SuperHighway" has attracted considerable attention. It offers the possibility to access information from around the world in support of many important applications in areas such as finance, manufacturing, and transportation (e.g., global risk management, integrated supply chain management, global in-transit visibility.) Unfortunately, there are significant challeng...

Discussion • The proposed architecture and data flow are designed to transform raw HIE data into trustworthy data and improve data integrity by examining data quality attributes of physiological compatibility, completeness, and redundancy. • By filtering out previously processed data and retaining only new HIE data, the architecture eliminates duplicate processing of discrete data from incoming...

We present a tool, called POIESIS, for automatic ETL process enhancement. ETL processes are essential data-centric activities in modern business intelligence environments and they need to be examined through a viewpoint that concerns their quality characteristics (e.g., data quality, performance, manageability) in the era of Big Data. POIESIS responds to this need by providing a user-centered e...

It is inadequate to just assure the functional requirements. Quality of service (QoS) must also be satisfied. An important challenge for developing efficient Service Oriented Architecture (SOA) is to maintain the QoS attributes because of compositional and dynamical environment of SOA. It is significant to scrutinize how quality attributes are supported by SOA. However, implementation of SOA pr...

It is well known that the software process in place impacts the quality of the resulting product. However, the specific way in which this effect occurs is still mostly unknown and reported through anecdotes. To gather a better understanding of such relationship, a very large survey has been conducted during the last year and has been completed by more than 100 software developers and engineers ...

Data freshness has been identified as one of the most important data quality attributes in information systems. This importance increases especially in the context of systems that integrate a large set of autonomous data sources. In this paper we describe a quality evaluation framework which allows evaluation of data freshness in different architectural contexts. We also show how this quality f...

The purpose of this study is to examine the relationship between local government services and the overall satisfaction of users with the e–recruitment website (e–job website) in Taiwan. A two–dimensional mean value matrix (TDMVM) technique was used to explore the identification, classification, and application of website service quality. The results show that the asymmetrical relationship betw...
