SIGMOD Test-of-Time Award
Executing SQL over Encrypted Data in the Database-Service-Provider Model
Hakan Hacigumus, Bala Iyer, Chen Li, Sharad Mehrotra
This paper from the SIGMOD 2002 Conference remarkably anticipated the world of "Database as Service" which did come about and continues to grow in importance. To get a sense of how visionary the work was, consider that this paper was published in June 2002 (and thus accepted in Jan 2002), even a couple of months before Amazon EC2 and S3 services were launched (of course, Amazon RDS and SQL Azure came much later). The core of the paper focuses on the challenges of how to leverage cloud services while keeping some of the information (at the discretion of the enterprise/user) hidden from the service provider. Beyond the specific algorithmic details, the key contribution is the framework: (i) introduction of a mapping function, and (ii) query splitting logic to ensure how the work can be distributed across cloud and client when some information is encrypted. Is this framework used by enterprises today? As best as we can tell, the answer is perhaps no. But, is the framework interesting and has real possibilities of adoption and further impact and more follow-on by research community? Absolutely. In summary, this paper is one of the early papers to foresee the world of Database as Service (before any one of us were working on that problem). The specific technical focus was dealt with reasonable depth. The impact of the technical focus has not yet been seen by the industry but this paper has the possibility of inspiring much more follow-on work/thinking (beyond 140+ citations it already has in ACM Digital Library).

High-Performance Complex Event Processing over XML Streams
Barzan Mozafari, University of California, Los Angeles; Kai Zeng, University of California, Los Angeles; Carlo Zaniolo, University of California, Los Angeles
Much research attention has been given to delivering high-performance systems that are capable of complex event processing (CEP) in a wide range of applications. However, many current CEP systems focus on processing efficiently data having a simple structure, and are otherwise limited in their ability to support efficiently complex continuous queries on structured or semi-structured information. However, XML streams represent a very popular form of data exchange, comprising large portions of social network and RSS feeds, financial records, configuration files, and similar applications requiring advanced CEP queries. In this paper, we present the XSeq language and system that support CEP on XML streams, via an extension of XPath that is both powerful and amenable to an efficient implementation. Specifically, the XSeq language extends XPath with natural operators to express sequential and Kleene-* patterns over XML streams, while remaining highly amenable to efficient implementation. XSeq is designed to take full advantage of recent advances in the field of automata on Visibly Pushdown Automata (VPA), where higher expressive power can be achieved without compromising efficiency (whereas the amenability to efficient implementation was not demonstrated in XPath extensions previously proposed). We illustrate XSeq's power for CEP applications through examples from different domains, and provide formal results on its expressiveness and complexity. Finally, we present several optimization techniques for XSeq queries. Our extensive experiments indicate that XSeq brings outstanding performance to CEP applications: two orders of magnitude improvement are obtained over the same queries executed in general-purpose XML engines.

For innovative and highly significant contributions of enduring value to the development, understanding, or use of database systems and databases.
Bruce Lindsay has been a leader and inventor in many of the key systems initiatives in the data management field. As a member of the original System R team, the R* project, the Starburst project, and then several content management projects, Bruce has created fundamental technologies in a broad set of database areas, including core relational databases (authorization, high performance transactions, locking and deadlock detection), extensible databases (object management, type management, production rules for query processing), distributed databases (snapshots, distributed DDL, presumed commit, presumed abort, distributed query processing), and management of unstructured data (XML, novel indexing). He thinks broadly and has uncanny intuition for the system-level issues that has led to his innovations to have lasting impact on commercial database products.
