Patricia G. Selinger is an American computer scientist and IBM Fellow, best known for her work on relational database management systems.
She received A.B. (1971), S.M. (1972), and Ph.D. (1975) degrees in applied mathematics from Harvard University. [1]
She played a fundamental role in the development of System R, a pioneering relational database implementation, and wrote the canonical paper on relational query optimization. [2] She is a pioneer in relational database management and inventor of the technique of cost-based query optimization. She was a key member of the original System R team that created the first relational database research prototype. [3] [4] [5] The dynamic programming algorithm for determining join order proposed in that paper still forms the basis for most of the query optimizers used in modern relational systems. She also established and led IBM’s Database Technology Institute, considered one of the most successful examples of a fast technology pipeline from research to development and personally has technical contributions in the areas of database optimization, data parallelism, distributed data, and unstructured data management. [6] [7] Before her retirement from IBM, she was the Vice President of Data Management Architecture and Technology at IBM.
Dr. Selinger was appointed an IBM Fellow in 1994, IBM’s highest technical recognition, and is an ACM Fellow (2009) and a Fellow of the American Academy of Arts and Sciences. [8] [9] She was also elected a member of the National Academy of Engineering (1999) for leadership and contributions to relational database technology.
Dr. Selinger has published more than 40 papers, and also received the ACM Systems Software Award for her work on System R. She received the SIGMOD Innovation Award in 2002, the highest ACM award given in the area of data management. [10]
From 2014 through 2016, Dr. Selinger was the Chief Technology Officer at Paradata (Paradata.io) where she worked on challenging problems in data harmonization, curation, provenance, and entity resolution to provide transparency to the supply chain. Paradata technology transforms real-time data into verified insights and executable actions.
From 2017 through 2018, Dr. Selinger served as a Principal Architect at Salesforce.com. She is now retired.
In computing, a database is an organized collection of data or a type of data store based on the use of a database management system (DBMS), the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an application associated with the database.
A relational database is a database based on the relational model of data, as proposed by E. F. Codd in 1970. A system used to maintain relational databases is a relational database management system (RDBMS). Many relational database systems are equipped with the option of using SQL for querying and updating the database.
Structured Query Language (SQL) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS). It is particularly useful in handling structured data, i.e., data incorporating relations among entities and variables.
Edgar Frank "Ted" Codd was an English computer scientist who, while working for IBM, invented the relational model for database management, the theoretical basis for relational databases and relational database management systems. He made other valuable contributions to computer science, but the relational model, a very influential general theory of data management, remains his most mentioned, analyzed and celebrated achievement.
Db2 is a family of data management products, including database servers, developed by IBM. It initially supported the relational model, but was extended to support object–relational features and non-relational structures like JSON and XML. The brand name was originally styled as DB/2, then DB2 until 2017 and finally changed to its present form.
IBM System R is a database system built as a research project at IBM's San Jose Research Laboratory beginning in 1974. System R was a seminal project: it was the first implementation of SQL, which has since become the standard relational data query language. It was also the first system to demonstrate that a relational database management system could provide good transaction processing performance. Design decisions in System R, as well as some fundamental algorithm choices, influenced many later relational systems.
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. MonetDB has been applied in high-performance applications for online analytical processing, data mining, geographic information system (GIS), Resource Description Framework (RDF), text retrieval and sequence alignment processing.
Ronald Fagin is an American mathematician and computer scientist, and IBM Fellow at the IBM Almaden Research Center. He is known for his work in database theory, finite model theory, and reasoning about knowledge.
Alberto O. Mendelzon was an Argentine-Canadian computer scientist who died on June 16, 2005.
David Maier is the Maseeh Professor of Emerging Technologies in the Department of Computer Science at Portland State University. Born in Eugene, OR, he has also been a computer science faculty member at the State University of New York at Stony Brook (1978–82), Oregon Graduate Center, University of Wisconsin, Oregon Health & Science University (2001–present) and National University of Singapore (2012–15). He holds a B.A. in Mathematics and Computer Science from the University of Oregon and a Ph.D. in Electrical Engineering and Computer Science from Princeton University (1978).
Michael Ralph Stonebraker is a computer scientist specializing in database systems. Through a series of academic prototypes and commercial startups, Stonebraker's research and products are central to many relational databases. He is also the founder of many database companies, including Ingres Corporation, Illustra, Paradigm4, StreamBase Systems, Tamr, Vertica and VoltDB, and served as chief technical officer of Informix. For his contributions to database research, Stonebraker received the 2014 Turing Award, often described as "the Nobel Prize for computing."
