'''Object-PL/SQL''' ('''[[Object-oriented programming|Object]]-Procedural Language/[[Structured Query Language]]''' or simply '''O-PL/SQL''') is a methodology of usage ofusing the [[Oracle Corporation]]'s [[Procedural programming|procedural]] extension [[programming language|language]] for [[SQL]] and the [[Oracle Database|Oracle relational database]].<ref name="CITDK">{{cite web|url=http://www.cit.dk/cot/reports/reports/Case4/18/cot-4-18.pdf|title=Experiences with Object Oriented Development in PL/SQL|author=Lassan, Alan R., Due, Jacob Steen|date=13 June 2000|publisher=The danish Nationl Center for IT Research|accessdate=15 April 2012}}</ref> afterThe theadditional features of thefrom version 7 and furtherother improvementimprovements, lead to one of the large-scale environment implementations of the [[object-oriented database]] paradigm.<ref name="DBAORA">{{cite web|url=http://www.dba-oracle.com/t_edb_pl_sql_features_release.htm|title=PL/SQL Features by Release|author=Cunningham, Lewis|publisher=Burleson Consulting|accessdate=15 April 2012}}</ref> leading to one of the means of large-scale environment implementations of the [[object-oriented database]] paradigm.
Although PL/SQL's general [[Syntax (programming languages)|syntax]] formerly used to resemble that of [[Ada (programming language)|Ada]] or [[Pascal (programming language)|Pascal]], there were many improvements that mainly include mainly the ''Java embedding code''<ref name="STKOVER">{{cite web|url=http://stackoverflow.com/questions/70072/when-should-you-use-java-stored-procedures-with-an-oracle-database-what-are|title=When Should you use Java Stored Procedures with an Oracle Database, what are the Drawbacks?|publisher=Stack Overflow|accessdate=15 April 2012}}</ref> and the ''object-oriented syntax''<ref name="ETUT">{{cite web|url=http://etutorials.org/SQL/Oracle+PL+SQL+Language+Pocket+Reference/Chapter+1.+Oracle+PLSQL+Language+Pocket+Reference/1.16+Oracles+Object-Oriented+Features/|title=Oracle's Object-Oriented Features|publisher=etutorial.org|accessdate=16 April 2012}}</ref> inside the SQL.
The mixing and embedding,inof [[Database trigger|triggers]] and [[stored procedure]]s of the Java and the SQL languages was one of the breakthrough points up to support the use of [[PL/SQL]] in a ''OO'' paradigm.<ref name="SAMS">Benett, 2002:144</ref> The includinginclusion in the SQL syntax of statements likesuch as <nowiki>[class].[object]</nowiki>, and the implementation of the object ''type''<ref name="TOP10"/> (like any OO language), completed the minimum requisites to a mapping approach in an extended SQL language without use of [[Persistence framework|specific mapping software]].<ref name="BALES">Bales, 2007:107-209</ref>
