The overall scientific goal of Stratosphere is to research and prototypically develop a novel, database-inspired information management system for the Cloud, for analyzing, aggregating, and querying very large data collections, made of either textual or (semi-) structured data. In order to achieve this goal, the proposed research unit is comprised of world-class experts in the areas of distributed systems, query processing, query optimization, information extraction, information integration and cleansing, security, and privacy. Through interdisciplinary orientation of many of its members, the research unit has close ties to potential users and can therefore validate the practical relevance of the invented technologies for several application domains, e.g., life-sciences, scientific applications, and for linked data. The geographical proximity of all research group members greatly facilitates collaboration and enables the establishment of regular joint seminars. Several research unit members will augment the research unit with additional resources, by bringing in own research staff or equipment. In addition, the research unit will be able to rely on a Cloud test-bed provided by TU Berlin and Humboldt-Universität zu Berlin. For large-scale demonstrations, the research unit will also have access to a full Cloud system setup at KIT with the support of Yahoo, HP, and Intel. The research unit will be able to use Hadoop, the open-source implementation of a data processor for a Cloud platform, as well as the opensource implementation of the JAQL query language, as a starting point for its research. Information management infrastructure researchers at IBM, Cloud providers at KIT, and users at the Potsdam Institut für Klimafolgenforschung (PIK) have already expressed interest in collaborating with the research unit if it is established, in order to assess the potential of Cloud computing for information management. We envision that the Stratosphere Cloud information management system research will serve as a basis for subsequent research activities in advanced areas of information management, such as scientific computing, web analysis, or next generation business intelligence. Stratosphere will leverage and extend open-source efforts like Hadoop and JAQL. We aim for lasting impact of our research by donating the code we develop to the opensource community. Our effort will enable other researchers and practitioners to use our implementations and to build on our work. After successful completion of the research unit, the principal investigators plan to continue and extend the research through a collaborative research center (SFB), which could build on our research results to provide near real-time processing on streaming data sets in a parallel environment in conjunction with considerations on business models, privacy, programming paradigms, and applications. We envision that our research will also impact the curriculum of database and distributed system classes. Overall, we expect that the Stratosphere research activities will lay the foundation for a Berlin-Brandenburg Information Management Group with long-term research collaboration, aligned curricula, and shared lectures among the participating universities.

Stratosphere的总体科学目标是研究和原型开发一种新颖的，受数据库启发的云信息管理系统，用于分析，聚合和查询由文本或（半）结构化数据组成的非常大的数据集合。为了实现这一目标，拟议的研究单位是由世界一流的专家在分布式系统，查询处理，查询优化，信息提取，信息集成和清洗，安全和隐私等领域。通过其许多成员的跨学科方向，研究单位与潜在用户有着密切的联系，因此可以验证发明技术对几个应用领域的实际相关性，例如，生命科学、科学应用和关联数据。所有研究小组成员在地理上都很接近，这极大地促进了合作，并使得能够定期举办联合研讨会。若干研究单位成员将增加研究单位的额外资源，带来自己的研究人员或设备。此外，该研究单位将能够依靠柏林工业大学和柏林洪堡大学提供的云测试台。对于大规模的演示，研究单位还将在雅虎，惠普和英特尔的支持下访问KIT的完整云系统设置。研究单位将能够使用Hadoop，云平台数据处理器的开源实现，以及JAQL查询语言的开源实现，作为其研究的起点。IBM的信息管理基础设施研究人员、KIT的云提供商以及波茨坦气候研究所（PIK）的用户已经表示有兴趣与该研究机构合作，以评估云计算在信息管理方面的潜力。我们设想，平流层云信息管理系统研究将作为信息管理高级领域（如科学计算、网络分析或下一代商业智能）后续研究活动的基础。Stratosphere将利用和扩展Hadoop和JAQL等开源工作。我们的目标是通过将我们开发的代码捐赠给开源社区来实现我们研究的持久影响。我们的努力将使其他研究人员和从业人员能够使用我们的实现并在我们的工作基础上进行构建。在成功完成研究单元后，主要研究人员计划通过合作研究中心（SFB）继续并扩展研究，该中心可以建立在我们的研究成果基础上，结合商业模式，隐私，编程范式和应用程序的考虑，在并行环境中提供对流数据集的近实时处理。我们设想，我们的研究也将影响数据库和分布式系统类的课程。总体而言，我们预计平流层研究活动将为柏林-勃兰登堡信息管理小组奠定基础，该小组将在参与大学之间进行长期研究合作，调整课程和共享讲座。
