The rise of Data Science as a discipline has also led to the creation of new courses whose content significantly overlaps that of an introductory database course. This column presents a series of perspectives on data (base/science) education to help educators think about what we should be teaching in our courses, and what resources we should use to teach them. This episode contains two contributions. The first discusses a recent effort called OpenDS4All, whose goal is to accelerate the creation of Data Science curricula by providing a “starter set” of open source data science training materials, including PowerPoint slides and Jupyter Notebooks with Python code. The second presents a process for making pedagogical decisions of how to construct a data management class given the wealth of content that can be included.","PeriodicalId":21740,"journal":{"name":"SIGMOD Rec.","volume":"8 1","pages":"49-51"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78984425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Work in the early 1970s, by Turing winner Jim Gray and others, established a standard set of techniques for transaction management. These remain the basis of most commercial and open-source platforms [1], and they are still taught in university database classes. So why is important research still needed in this topic? The technology environment keeps evolving, and new performance characteristics mean that new algorithms and system designs become appropriate. This perspective will summarise the early work, and point to how the field has continued to progress.","PeriodicalId":21740,"journal":{"name":"SIGMOD Rec.","volume":"101 1","pages":"14"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76732378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to analyze the existing and (more importantly) future very large time series collections, new technologies and the development of more efficient and smarter algorithms are required. The two editions of the Interdisciplinary Time Series Analysis Workshop brought together data analysts from the fields of computer science, astrophysics, neuroscience, engineering, electricity networks, and music. The focus of these workshops was on the requirements of different applications in the various domains, and also on the advances in both academia and industry, in the areas of time-series management and analysis. In this paper, we summarize the experiences presented in and the results obtained from the two workshops, highlighting the relevant state-ofthe- art-techniques and open research problems.","PeriodicalId":21740,"journal":{"name":"SIGMOD Rec.","volume":"1 1","pages":"36-40"},"PeriodicalIF":0.0,"publicationDate":"2019-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90625815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective is an educating and rewarding experience for both the authors and the reviewers. The actionable goals are: 1. Maximize review depth and breadth. For depth, optimizing the assignment of papers to reviewers is of key importance; \"low confidence\" reviews should be few to none, in order for reviewers to provide extensive and useful comments to the authors. To cover the breadth and to address controversial issues, recruit as many reviewers as needed to converge to a unanimous set of comments. 2. Ensure that all submissions are treated equally fairly by experts in the respective domains. 3. Obtain as much input from the authors as possible during the process. Enabling author feedback is the key step in the process. 4. Allow re-evaluation of papers with non-critical flaws through revisions.","PeriodicalId":21740,"journal":{"name":"SIGMOD Rec.","volume":"10 1","pages":"47-54"},"PeriodicalIF":0.0,"publicationDate":"2019-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80676030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
