数据移动技术的选择与实现

数据移动技术是分布式数据库中非常重要的技术之一。本归纳总结了分布式数据库中的数据移动技术，从本质上将现有的数据移动技术分为在线、同步、复制三类技术。在线技术系统可以达到绝对的一致性，但该技术对网络要求很高，且在节点较少时才比较有效。同步技术可以支持大量节点，异构和级联环境，要求有效的网络连接，存在一定的一致性延时。复制技术比较灵活，支持大量节点，异构和级联环境；可以在较好的网络环境，也可以在无直接或网络环境恶劣的情况下使用；存在一定的一致性延时，也可达到准实时的一致性。这三类数据移动技术的应用和选择，主要取决于业务需求和可用的技术架构以及系统对一致性和延时的要求。

Using stakeholder feedback to improve online professional development opportunities

Abstract

Traditional professional development is often characterized as being expensive, time consuming, and lacking impact. In contrast, online professional development provides greater flexibility and is becoming increasingly popular for school personnel. In this article, we report the process and outcomes of gathering feedback to adapt traditional in-person to online training differentiated for the participants to maximize utility, efficiency, and effectiveness in meeting the needs of key stakeholders. Focus groups were conducted with teachers, administrators, and other specialists to gather feedback on content as well as how online learning modules (OLMs) could be tailored to meet specific school site and team needs. We discuss our findings in the context of continuing efforts to improve general and specific professional development opportunities.

Enhancing the facilitation of online groups in higher education: a review of the literature on face-to-face and online group-facilitation

There still appears to be a gap between what online learning promises and what it can deliver in terms of student learning. Developments in online pedagogies and professional learning appear to lag behind the developments in technology and the promised benefits of technological transformation may not be realised. In this paper, we bring together perspectives that highlight vital aspects of online group-learning by reviewing the group-facilitation literature and the latest online learning literature to interrogate the pedagogical theories and practices currently used in online group-learning in higher education. We specifically focus on the interpersonal interactions between teachers and students, which are described in the online learning literature using the terms instructor immediacy, teaching presence, and social presence. We note differences in the literature regarding how teacher presence is interpreted and enacted and we expound the importance of the personal characteristics of the online teacher. Finally, we provide some signposts that might help course designers and teachers to improve online group learning: the intentional use of effective online learning pedagogies; a deeper understanding of what constitutes teacher presence; and strategies to enact that teacher presence with online groups. Recommendations for further research in online group facilitation are provided.
