text: The core IDE exposes an API that other teams in Oracle use to build extensions to JDeveloper. BPEL, Portal, Business Intelligence and other components of the Oracle platform all build their design-time tools on top of JDeveloper. To accommodate to Sun Microsystems (and thus NetBeans) acquisition versions released after 2012 are sharing significant code with NetBeans platform. The same IDE platform also serves as the basis of another Oracle product, SQL Developer, which Oracle Corporation promotes specifically to PL/SQL and database developers.
