According to you why is Relational Database Management System is an important idea?ĭon Chamberlin: In the 1960s, computer time was very expensive, costing hundreds of dollars per minute. Tell us about the early days of relational database systems. Pramod:Yeah I can imagine that computers in 1960. You could sign up for a session on the computer with luck, you might get one session per day.ĭuring my college years, I had a summer job at a service bureau, where I would hang tapes for input to an IBM 7090 mainframe computer, and manage the line-printer that printed the output. I loved programming that machine and wrote a program to play tic-tac-toe against a human on a keyboard. There was precisely one computer on the Harvey Mudd campus, an IBM 1620 in the basement of the science building. Pramod: Don tell us about your early life, when were you introduced to Computers?ĭon Chamberlin: The story started in the 1960’s when I was a college student at Harvey Mudd College in southern California.
He is an ACM, IBM, IEEE fellow and has won many prestigious awards for his contributions. Well, Today I have the opportunity to speak to Don Chamberlin, the original designer of SQL database language. I always wondered how these brilliant men designed this beautiful and natural Language called SQL. In 1970 Don Chamberlin and Raymond Boyce two IBM Researchers developed SQL. Communication has been made so easy using SQL. SQL (Structured Query Language) is used to communicate with a database.
These systems manage a massive amount of data efficiently and allow users to perform multiple tasks at ease. Today Every computer engineer knows the importance of database and database management systems. Pramod: Hello, Listeners Welcome to 11th Episode of Mapping The Journey. He likes to teach and recently taught a Java programming class at University of California, Santa Cruz. For the last several years he has been a judge and problem contributor to the ACM International Collegiate Programming Contest. With Jonathan Robie and Dana Florescu, he designed the Quilt language, which became the basis for the design of XQuery. More recently, he was a member of the W3C Working Group on XML Query Languages and an editor of the XPath 2.0 and XQuery language specifications, which became W3C Recommendations in 2007. He was a member of the System R research team that developed much of today’s relational database technology and, together with Ray Boyce, he designed the original SQL database language. For many years, he worked at Almaden Research Center, researching database languages and systems. degree from Harvey Mudd College and a Ph.D.
