[1] [2] The choice of data orientation is a trade-off and an architectural decision in databases, query engines, and numerical ...

His primary area of research is database systems, with contributions to stream databases, distributed databases, graph databases, and column-store databases. [3] He helped create C-Store, a column-oriented database, and HadoopDB, a hybrid of relational databases and Hadoop. Both database systems were commercialized by companies.
C-Store is a database management system (DBMS) based on a column-oriented DBMS developed by a team at Brown University, Brandeis University, Massachusetts Institute of Technology and the University of Massachusetts Boston including Michael Stonebraker, Stanley Zdonik, and Samuel Madden.
MonetDB is an open-source column-oriented relational database management system (RDBMS) originally developed at the Centrum Wiskunde & Informatica (CWI) in the Netherlands.It is designed to provide high performance on complex queries against large databases, such as combining tables with hundreds of columns and millions of rows.
Database design is the organization of data according to a database model. The designer determines what data must be stored and how the data elements interrelate.
