Project #2 – Checkpoint #2 is due Friday October 19th @ 11:59pm. CMU 15-445/645 (Fall 2018) 4 QUERY OPTIMIZATION Remember that SQL is declarative. → User tells the DBMS what answer they want, not how to get the answer. There can be a big difference in performance based on plan is used: → See last week: 1.3 hours vs. 0.45 seconds CMU 15-445/645 (Fall 2018) 5 IBM SYSTEM R First implementation of a query optimizer. People argued that the DBMS could never choose a query plan better than what a human could write. A lot of the concepts from System R’s optimizer are still used today. CMU 15-445/645 (Fall 2018) 6 QUERY OPTIMIZATION Heuristics / Rules → Rewrite the query to remove stupid / inefficient things. → Does not require a cost model. Cost-based Search → Use a cost model to evaluate multiple equivalent plans and pick the one with the lowest cost.

Lecture #02: Intermediate SQL 15-445/645 Database Systems (Fall 2020) https://15445.courses.cs.cmu.edu/fall2020/ Carnegie Mellon University Prof. Andy Pavlo 1 Relational Languages Edgar Codd published a major paper on relational models in the early 1970s. Originally, he only defined the mathematical notation for how a DBMS could execute queries on a relational model DBMS. The user only needs to specify the result that they want using a declarative language (i.e., SQL). The DBMS is responsible for determining the most efficient plan to produce that answer. Relational algebra is based on sets (unordered, no duplicates). SQL is based on bags (unordered, allows duplicates). 2 SQL History Declarative query lanaguage for relational databases. It was originally developed in the 1970s as part of the IBM System R project. IBM originally called it “SEQUEL” (Structured English Query Language). The name changed in the 1980s to just “SQL” (Structured Query Language). The language is comprised of different classes of commands: 1. Data Manipulation Language (DML): SELECT, INSERT, UPDATE, and DELETE statements. 2. Data Definition Language (DDL): Schema definitions for tables, indexes, views, and other objects. 3. Data Control Language (DCL): Security, access controls. SQL is not a dead language. It is being updated with new features every couple of years. SQL-92 is the minimum that a DBMS has to support to claim they support SQL. Each vendor follows the standard to a certain degree but there are many proprietary extensions. 3 Aggregates An aggregation function takes in a bag of tuples as its input and then produces a single scalar value as its output. -

Oracle Corporation
ORACLE CORPORATION The Oracle Corporation is an American global computer technology corporation, headquartered in Redwood City, California. The company primarily specializes in developing and marketing computer hardware systems and enterprise software products – particularly its own brands of database management systems. In 2011 Oracle was the second- largest software maker by revenue, after Microsoft.[3] The company also develops and builds tools for database development and systems of middle-tier software, enterprise resource planning (ERP) software, customer relationship management (CRM) software and supply chain management (SCM) software. Larry Ellison, a co-founder of Oracle, served as Oracle's CEO from founding. On September 18, 2014, it was announced that he would be stepping down (with Mark Hurd and Safra Catz to become CEOs). Ellison became executive chairman and CTO.[4] He also served as the Chairman of the Board until his replacement by Jeffrey O. Henley in 2004. On August 22, 2008, the Associated Press ranked Ellison as the top-paid chief executive in the world.[5] Larry Ellison , Ellison was born in New York City but grew up in Chicago. He studied at the University of Illinois at Urbana–Champaign and the University of Chicago without graduating before moving to California in 1966. While working at Ampex in the early 1970s, he became influenced by Edgar F. Codd's research on relational database design, which led in 1977 to the formation of what became Oracle. Oracle became a successful database vendor to mid- and low- Larry Ellison in October 2009. range systems, competing with Sybase and Microsoft SQL Server, Born August 17, 1944 (age 71) which led to Ellison being listed by Forbes Lower East Side, Manhattan, New York, U.S.
