Proceedings of the 2014 ACM SIGMOD International Conference on Management of Data

Abstract

We are delighted to welcome you to SIGMOD 2014, the 2014 edition of the ACM SIGMOD International Conference on Management of Data, at Snowbird, Utah, in the Rocky Mountains of the United States. Snowbird is a mountain ski and summer resort. Many attractions, parks, and recreational areas -- including the Yellowstone, Zion, Bryce Canyon, Capitol Reef, Great Basin, Canyonlands, and Arches national parks -- are within a day's drive. The mountain scenery of Snowbird is also adjacent to the urban environment of Salt Lake City. SIGMOD 2014 hosts an exciting technical program, with two keynote talks, by Maurice Herlihy (Brown University) and Eric Sedlar (Oracle Labs); a panel session on "Should we all be teaching 'Intro to Data Science' instead of 'Intro to Databases'?," by Bill Howe (University of Washington), Michael Franklin (University of California, Berkeley), Juliana Freire (New York University), James Frew (University of California, Santa Barbara), Tim Kraska (Brown University), and Raghu Ramakrishnan (Microsoft Corporation); an industrial panel on "Are We Experiencing a Big Data Bubble?," by Fatma Özcan (IBM Almaden Research Center), Daniel Abadi (Yale University), Marcel Kornacker (Cloudera), C Mohan (IBM Almaden Research Center), Karthik Ramasamy (Twitter), and Janet Wiener (Facebook, Inc. ); 107 research paper presentations; 6 tutorials; 30 demonstrations; and 15 industrial presentations selected from among 44 submissions. In addition to having 25-minute presentation slots, research papers are included in one of two Research Plenary Poster Sessions. One of these sessions is jointly for PODS and SIGMOD research papers, to deepen the ties between the two conferences. SIGMOD 2014 includes several technical and social events designed specifically for student attendees. The SIGMOD/PODS 2014 Ph.D. Symposium, the Undergraduate Research Poster Competition, and the New Researcher Symposium are all established components of the SIGMOD program and are all part of SIGMOD 2014. The conference also hosts a session dedicated to highlighting the finalists of the SIGMOD Programming Contest. (This year's task is to implement a multidimensional, high-throughput, in-memory indexing system.) In addition, the conference includes a Sponsor Session for our industry partners to present the cool things they have done and introduce career opportunities in industry. This helps bring student attendees together with our Gold, Platinum, and Diamond sponsors. A "vis-à-vis" meeting aimed at helping Ph.D. students meet internationally recognized researchers in their research areas, will also be organized to exchange ideas and receive guidance in a relaxed social setting. We are immensely grateful to the many researchers who have shaped the conference program. In particular, we thank the Keynotes Chair Gustavo Alonso (ETH Zürich), the Panels Chairs Susan Davidson (University of Pennsylvania) and Sunita Sarawagi (IIT Bombay), the Tutorial Chairs Chris Jermaine (Rice University) and Yufei Tao (Chinese University of Hong Kong), the Industrial Program Chairs Fatma Özcan (IBM Almaden) and Nesime Tatbul (Intel Labs and MIT), together with the 13 members of the Industrial Program Committee, the Demonstrations Chairs Wolfgang Lehner (Technische Universität Dresden) and Bettina Kemme (McGill University), together with the 53 members of the Demonstration Program Committee, the Workshops Chair Anastasia Ailamaki (EPFL), the Undergraduate Research Program Chairs Mario Nascimento (University of Alberta) and Anastasios Kementsietsidis (IBM TJ Watson Laboratories), the New Researcher Symposium Chairs Anish Das Sarma (Google Research) and Alexandra Meliou (University of Massachusetts, Amherst). We also express our enormous gratitude to the 13 Program Committee "area coordinators," Lei Chen (Hong Kong University of Science and Technology), Michael Franklin (University of California, Berkeley), Alfons Kemper (Technical University of Munich), Laks Lakshmanan (University of British Columbia), Ioana Manolescu (Inria Saclay), Tova Milo (Tel Aviv University), Elke Rundensteiner (Worcester Polytechnic Institute), Ken Salem (University of Waterloo), Dennis Shasha (New York University), Divesh Srivastava (AT&T Labs-Research), Kian-Lee Tan (National University of Singapore), Patrick Valduriez (Inria Sophia- Antipolis Méditerranée), and Xiaokui Xiao (Nanyang Technological University) along with the 111 members of the SIGMOD 2014 Program Committee. This year we had two submission cycles for SIGMOD research papers -- one in mid-September and the second one in mid-December. We received 421 research paper submissions across two cycles. As usual, each paper was reviewed by at least three program committee members, followed by a discussion led by the area coordinators. We followed a review process that resembles journal reviewing -- papers went through multiple rounds of reviews until a final decision was taken. Out of 421 submissions, 29 were directly accepted, 102 went
