It includes coverage of PL/SQL (Oracle's procedural extension of SQL and Informix object extensions, as well as coverage of J/SQL (a version of SQL that is embedded in Java), which is rapidly becoming a viable database application programming language.;Standardized in 1989 by the American National Standards Institute (ANSI), SQL is an industry-standard language used for data definition, data manipulation, data management, access protection and transition control.
