[Monetdb-developers] PhD opening at CWI - Adaptive indexing techniques for modern database systems

by Stratos Idreos

Subject: Adaptive indexing techniques for modern database systems. The Centrum Wiskunde & Informatica (CWI) has a full time vacancy for a talented PhD candidate in the Database Architectures group (http://www.cwi.nl/en/research-groups/Database-Architectures). The position is in the broad area of adaptive indexing techniques for modern database systems. Adaptive indexing is a major challenge in database research; it tries to completely alleviate the need for indexing and tuning steps leading to database systems that require no physical design set-up and can cope immediately with any workload. This leads to database systems that are instantly usable and thus more applicable to numerous new applications that now consider databases too slow, too complex and too old. This position will focus specifically on adaptive indexing for extremely large databases where traditional indexing represents a major bottleneck. The Database Architectures group is one of the world-wide leading groups in system-oriented database research, e.g., it received the 10-year best paper award at VLDB 2009 for their pioneering research on hardware-aware database technology and the column-store model and the 2011 ACM SIGMOD Jim Gray Dissertation award for the database cracking work. The group has a unique methodology that combines fundamental database research with active participation of all group members in database engineering, centred around the open-source analytical database system MonetDB (http://www.monetdb.org/). An internship at one of the partnering database research labs world-wide is considered part of the PhD track. REQUIREMENTS The PhD candidates must have a master degree in computer science (or a 5 year diploma), (specialisation databases, distributed systems, software engineering) mathematics, or related fields. Preferable qualifications for candidates include proven research talent, system programming skills (C/C++), practical experience with using and implementing database systems, and software development in a team. Candidates are expected to have an excellent command of English, and good academic writing and presentation skills. CENTRUM WISKUNDE & INFORMATICA (CWI) Founded in 1946, the Centrum Wiskunde & Informatica (CWI) is the national research institute for mathematics and computer science in the Netherlands. It is located at the Science Park Amsterdam and is part of the “Netherlands Organisation for Scientific Research” (NWO). The institute is internationally focused and renowned for its high quality research, a substantial fraction of which is carried out in the framework of (inter)national programs. Over 160 researchers conduct pioneering research and share their acquired knowledge with society. More than 30 researchers are employed as professors at universities. The institute has generated twenty-one spin-off companies. CWI maintains excellent relations with industry and the academic world, both in the Netherlands as well as abroad. After their research careers at CWI, an increasing number of young staff members find employment in these sectors or in spin-off companies that are based on research results from CWI. Of course, library and computing facilities are first-rate. CWI's non-scientific services to its personnel include career planning, training and courses, assistance in finding housing, and tailor-made solutions to problems that may occasionally arise. TERMS AND CONDITIONS The terms of employment are in accordance with the Dutch Collective Labour Agreement for Research Institutes ("CAO-onderzoeksinstellingen"). Moreover CWI offers attractive working conditions, including flexible scheduling and help with housing for expat employees. The gross monthly salary, for an employee on a full time basis, is €2,037 during the first year and increases to €2,610 over a four year period. CWI also offers excellent and flexible terms of employment, including an employee pension fund. INFORMATION Additional information can be obtained from: dr.

[Monetdb-developers] PhD position at CWI Database Architecture group

by Stefan Manegold

CWI is an internationally renowned research institute in mathematics and computer science, located in Amsterdam, The Netherlands. The focus is on fundamental research problems, inspired by societal needs. Research is carried out in 18 research groups and a substantial fraction is carried out in the framework of (inter)national programs. VACANCY CWI has a vacancy for a talented PhD candidate in the DB Architectures group (http://www.cwi.nl/en/research-groups/Database-Architectures). DISTRIBUTED DATABASE ARCHITECTURES FOR SCIENCE APPLICATIONS The Database Architectures group is one of the world-wide leading groups in system-oriented database research, e.g., it received the 10-year best paper award at VLDB 2009 for their pioneering research on hardware-aware database technology and the column-store model. The group has a unique methodology that combines fundamental database research with active participation of all group members in database engineering, centered around the open-source analytical database system MonetDB (http://www.monetdb.org/). You will be expected to write both papers and contribute to this code base. The focus of the group is on hard core data management and for this position specifically on database architectures to support large scale scientific applications in the context of the SciLens project (http://www.scilens.org). The goal is to leverage the potential power of a 330 node dedicated database machine to improve science in, e.g., astronomy and seismology. (http://www.scilens.org/content/platform) CWI maintains excellent relations with industry and the academic world, both in the Netherlands as well as abroad. An internship at one of the partnering database research labs world-wide is considered part of the PhD track. After their research careers at CWI, many staff members find employment in these sectors or in spin-off companies based on research results from CWI.

[Monetdb-developers] Basics about MonetDB

by 叶亮

Hi, I'm a new comer with some questions about basic conceptions of MonetDB. 1. The executor I've ever found the executor of postgreSQL at src\backend\executor, but cannot make sure where it is like that in MonetDB src. MonetDB\MonetDB\src\gdk or MonetDB5-server\MonetDB5\src\mal ? 3. MAL MAL (MonetDB Assembly Language) is a script tool only for MonetDB or a common script language that can be applied to other softwares. Why it is a must in MonetDB ? 4. .mx files In MonetDB, .mx files are compiled to make .h and .c files generated.(in this way ?) Why is this routines ? (not just coding in .h and .c files directly) Yel ---- Best Regards richardroky(a)gmail.com
