The computing continuum enables new opportunities for managing big data pipelines concerning efficient management of heterogeneous and untrustworthy resources. We discuss the big data pipelines lifecycle on the computing continuum and its associated challenges, and we outline a future research agenda in this area. [ABSTRACT FROM AUTHOR]

This article proposes an architecture for vaccination information validation and tracking with a fog and cloud-based blockchain system, providing a privacy-aware and scalable approach for interoperable and effective data management. It evaluates the scalability of the underlying blockchain system by means of simulation. [ABSTRACT FROM AUTHOR]

Sharing data between organizations is difficult due to different database management systems imposing different schemas as well as security and privacy concerns. We leverage two proven NIST technologies to address the problem: Next Generation Database Access Control and the data block matrix. [ABSTRACT FROM AUTHOR]

Disk-based backup systems use data deduplication to replace redundant data chunks with references. These systems initially supported workloads from their tape-based predecessors, but changes to hardware and applications have forced them to adapt in interesting and challenging ways. [ABSTRACT FROM AUTHOR]

Quality-of-experience-oriented mechanisms, not currently available in traditional database management systems, allow a system to take into consideration user-specified requirements and to adjust its operations accordingly, based on user expectations. [ABSTRACT FROM PUBLISHER]

Novel approaches to network visualization and analytics use sophisticated metrics that enable rich interactive network views and node grouping and filtering. A survey of graph layout and simplification methods reveals considerable progress in these new directions. The first Web extra at http://youtu.be/ee8nr9LDHXw is a video segment showing dynamic graph layout results for visualizing evolving Internet connectivity. The global approach meets layout criteria--balanced quality and stability with nodes largely remaining stable, but clusters are compacted. The images are freeze frames of three time steps. The second Web extra at http://youtu.be/oWolTjZMGfo is a video segment showing dynamic graph layout results for visualizing evolving Internet connectivity. The incremental approach uses space efficiently. Motion is slow, smooth, and affine, and so is easy to follow, but quality degrades over time to ensure stable animation. [ABSTRACT FROM PUBLISHER]

Analysts exploring big data require more from information visualization, data analysis, and data management than these components can now deliver. New infrastructures must address the nature of exploration as well as data scale. The Web extra at http://youtu.be/K9PvskathGI is a video segment that gives an overview of how research in visual analytics can help tackle the challenges of managing and interpreting big data in various domains.

The best strategy for combating SQL injection, which has emerged as the most widespread website security risk, calls for integrating defensive coding practices with both vulnerability detection and runtime attack prevention methods. [ABSTRACT FROM PUBLISHER]

For enterprise datacenter operators who want to continue in-house operations, the future depends on documenting costs and performance. [ABSTRACT FROM PUBLISHER]

Facebook's Open Compute Project lets the community benefit from and contribute to improvements in power and water usage effectiveness, cost, and operation. [ABSTRACT FROM PUBLISHER]

Data-intensive science is now taking a place alongside theoretical science, experimental science, and computational science as a fundamental research paradigm. [ABSTRACT FROM AUTHOR]

The third in a series of articles providing basic information on legal issues facing people and businesses that operate in computing-related markets focuses on the responsibility to ensure privacy and data security. The featured Web extra is an audio podcast by Brian M. Gaff and Thomas J. Smedinghoff, two of the article's coauthors. [ABSTRACT FROM AUTHOR]

The complexity, diversity, and richness of experimental data on cellular systems are inspiring the development of computational analysis techniques that can directly prioritize and suggest new experiments. [ABSTRACT FROM AUTHOR]

Novel systems that scale out on demand, relying on replicated data and massively distributed architectures with clusters of thousands of machines, particularly those designed for real-time data serving and update workloads, amply illustrate the realities of the CAP theorem. The featured Web extra is a video interview with Yahoo's Raghu Ramakrishnan about CAP and the cloud. [ABSTRACT FROM AUTHOR]

New data-consistency models make it possible for cloud computing developers to replicate soft state without encountering the limitations associated with the CAP theorem. [ABSTRACT FROM AUTHOR]

The CAP theorem's impact on modern distributed database system design is more limited than is often perceived. Another tradeoff—between consistency and latency —has had a more direct influence on several well-known DDBSs. A proposed new formulation, PACELC, unifies this tradeoff with CAP.

Offering strong data protection to cloud users while enabling rich applications is a challenging task. Researchers explore a new cloud platform architecture called Data Protection as a Service, which dramatically reduces the per-application development effort required to offer data protection, while still allowing rapid development and maintenance.

Data obesity is a consequence of data gluttony and vice versa. [ABSTRACT FROM PUBLISHER]
