I am deeply humbled and honored for the opportunity to serve as the Chair of IEEE Technical Committee on Data Engineering (TCDE). TCDE is the flagship international society for data management and database systems researchers and practitioners. I thank the trust of all TCDE members. Let me start to pay our tribute to my predecessor, Kyu-Young Whang. Under his leadership, the visibility of TCDE ...

Efficient one-pass estimation of F0, the number of distinct elements in a data stream, is a fundamental problem arising in various contexts in databases and networking. We consider rangeefficient estimation of F0: estimation of the number of distinct elements in a data stream where each element of the stream is not just a single integer but an interval of integers. We present a randomized algor...

Although today’s computers provide huge amounts of main memory, the ever-increasing load of large data servers, imposed by resource-intensive decision-support queries and accesses to multimedia and other complex data, often leads to memory contention and may result in severe performance degradation. Therefore, careful tuning of memory mangement is crucial for heavy-load data servers. This paper...

ABSTRACT We analyze the database research publications of four major core database technology conferences (SIGMOD, VLDB, ICDE, EDBT), two main theoretical database conferences (PODS, ICDT) and three database journals (TODS, VLDB Journal, TKDE) over a period of 10 years (2001 2010). Our analysis considers only regular papers as we do not include short papers, demo papers, posters, tutorials or p...

Ç AS you are reading this issue, we just wrapped up a wonderful year. In the first 10 months, TKDE received a total of 1,225 submissions—915 were original submissions and 310 were revisions. These numbers present a slight increase from 2014. Proudly, we are the most popular flagship journal in the broad, data related areas, including data science, big data, data engineering, data mining, databa...

Data Engineering addresses algorithmic and systems design issues concerning management of data. While (relational) databases are probably the most comprehensive outcome of data engineering, several issues exist that are not amenable to straightforward relational modelling. As a result, research in data engineering continues on several fronts. This report is based on the author’s participation i...

We present two server-initiated protocols to improve the performance of distributed information systems (e.g. WWW). Our rst protocol is a hierarchical data dissemination mechanism that allows information to propagate from its producers to servers that are closer to its consumers. This dissemination reduces network traac and balances load amongst servers by exploiting geographic and temporal loc...

In this paper, we provide a brief overview of the Propel Distributed Services Platform, the infrastructure component of the recently announced Propel Commerce System. The Propel Distributed Services Platform is Internet infrastructure software that provides an integrated set of core services for developers of mission-critical, datacentric, e-business applications. It is designed to provide the ...

Many OLTP deployments in the web-scale industry start with a single-node open-source DBMS, add automation to manage many instances of the DBMS and then work with an open-source community to make things better via a large number of small improvements. The end result is far from perfect but frequently good enough to allow a business to focus on something other than the DBMS. The result is also fr...
