Material Information

This paper discusses key principles for the development of material property information management software systems. The growing need for automated material information management is fueled, in part, by the demand for higher efficiency in material testing, product design, and engineering analysis. But equally important, organizations are being driven by the need for consistency, quality, and traceability of data, as well as control of access to proprietary or sensitive information. Further, the use of increasingly sophisticated nonlinear, anisotropic, and multiscale engineering analyses requires both processing of large volumes of test data for the development of constitutive models and complex material data input for computer-aided engineering software. Finally, the globalization of economy often generates great needs for sharing a single “gold source” of material information between members of global engineering teams in extended supply chains. Fortunately, material property management systems have kept pace with the growing user demands and have evolved into versatile data management systems that can be customized to specific user needs. The more sophisticated of these provide facilities for (i) data management functions such as access, version, and quality controls; (ii) a wide range of data import, export, and analysis capabilities; (iii) data “pedigree” traceability mechanisms; (iv) data searching, reporting, and viewing tools; and (v) access to the information via a wide range of interfaces. In this paper, the important requirements for advanced material data management systems, future challenges, and opportunities, such as automated error checking, data quality characterization, identification of gaps in data sets, as well as functionalities and business models to fuel database growth and maintenance are discussed.

This paper discusses key principles for the development of materials property information management software systems. There are growing needs for automated materials information management in various organizations. In part these are fuelled by the demands for higher efficiency in material testing, product design and engineering analysis. But equally important, organizations are being driven by the need for consistency, quality and traceability of data, as well as control of access to sensitive information such as proprietary data. Further, the use of increasingly sophisticated nonlinear, anisotropic and multi-scale engineering analyses requires both processing of large volumes of test data for development of constitutive models and complex materials data input for Computer-Aided Engineering (CAE) software. And finally, the globalization of economy often generates great needs for sharing a single “gold source” of materials information between members of global engineering teams in extended supply-chains. Fortunately, material property management systems have kept pace with the growing user demands and evolved to versatile data management systems that can be customized to specific user needs.

Abstract In analyzing design and manufacturing tasks and their mutual interactions, it appears that the underlying information of these tasks is of the utmost importance. If this information is managed on an integral level, in a formalized, structured way, it can serve as a basis for the control of design and manufacturing processes. The ontological description that is used for this purpose is elaborated upon. It is indicated how an ontological description of the information content can govern design and manufacturing processes, and support their execution with all required information and functionality of resources. Moreover, it is expound how the ontological description can serve as the basis for integrating information that, in industry, is often dispersedly managed in separate coexisting data management systems. Furthermore, a framework is proposed for the implementation of an Information Management system as well as for the additional applications that utilize its functionality. Finally, a pilot implementation at a large Dutch industrial company is discussed concerning the aspect of integrating dispersedly managed information. This implementation is also compared to some currently available commercial solutions in this area that were tested at the company as well.

Technical Features

Background:Data management is an important, complex and multidimensional process in clinical trials. The execution of this process is very difficult and expensive without the use of information technology. A clinical data management system is software that is vastly used for managing the data generated in clinical trials. The objective of this study was to review the technical features of clinical trial data management systems.Methods:Related articles were identified by searching databases, such as Web of Science, Scopus, Science Direct, ProQuest, Ovid and PubMed. All of the research papers related to clinical data management systems which were published between 2007 and 2017 (n=19) were included in the study.Results:Most of the clinical data management systems were web-based systems developed based on the needs of a specific clinical trial in the shortest possible time. The SQL Server and MySQL databases were used in the development of the systems. These systems did not fully support the process of clinical data management. In addition, most of the systems lacked flexibility and extensibility for system development.Conclusion:It seems that most of the systems used in the research centers were weak in terms of supporting the process of data management and managing clinical trial's workflow. Therefore, more attention should be paid to design a more complete, usable, and high quality data management system for clinical trials. More studies are suggested to identify the features of the successful systems used in clinical trials.

Accuracy Of Results

Background:A clinical data management system is a software supporting the data management process in clinical trials. In this system, the effective support of clinical data management dimensions leads to the increased accuracy of results and prevention of diversion in clinical trials. The aim of this review article was to investigate the dimensions of data management in clinical data management systems.Methods:This study was conducted in 2017. The used databases included Web of Science, Scopus, Science Direct, ProQuest, Ovid Medline and PubMed. The search was conducted over a period of 10 years from 2007 to 2017. The initial number of studies was 101 reaching 19 in the final stage. The final studies were described and compared in terms of the year, country and dimensions of the clinical data management process in clinical trials.Results:The research findings indicated that none of the systems completely supported the data management dimensions in clinical trials. Although these systems were developed for supporting the clinical data management process, they were similar to electronic data capture systems in many cases. The most significant dimensions of data management in such systems were data collection or entry, report, validation, and security maintenance.Conclusion:Seemingly, not sufficient attention has been paid to automate all dimensions of the clinical data management process in clinical trials. However, these systems could take positive steps towards changing the manual processes of clinical data management to electronic processes.

Do So

The emergence of blockchains has fueled the development of resilient systems that can deal with Byzantine failures due to crashes, bugs, or even malicious behavior. Recently, we have also seen the exploration of sharding in these resilient systems, this to provide the scalability required by very large data-based applications. Unfortunately, current sharded resilient systems all use system-specific specialized approaches toward sharding that do not provide the flexibility of traditional sharded data management systems. To improve on this situation, we fundamentally look at the design of sharded resilient systems. We do so by introducing BYSHARD, a unifying framework for the study of sharded resilient systems. Within this framework, we show how two-phase commit and two-phase locking ---two techniques central to providing atomicity and isolation in traditional sharded databases---can be implemented efficiently in a Byzantine environment, this with a minimal usage of costly Byzantine resilient primitives. Based on these techniques, we propose eighteen multi-shard transaction processing protocols. Finally, we practically evaluate these protocols and show that each protocol supports high transaction throughput and provides scalability while each striking its own trade-off between throughput, isolation level, latency , and abort rate. As such, our work provides a strong foundation for the development of ACID-compliant general-purpose and flexible sharded resilient data management systems.
