All versions of Oracle database. Add a version-specific tag like oracle-11g-r2 if that context is important in the question. Do not use for Oracle products such as applications or middleware or other database products owned by Oracle, like MySQL or BerkeleyDB.
Oracle is a relational DBMS (Database Management System) created by Oracle Corporation. It supports a large number of languages and application development frameworks. Its primary languages are SQL, PL/SQL and Java. When asking a question with the oracle tag, please be sure to include the full version number, (i.e., 10.2.0.5, 11.2.0.4), in addition the relevant version-related tags described below.
Oracle makes plethora of documentation available at http://docs.oracle.com.
Tagging
Questions about SQL should be tagged sql. If the question applies to an Oracle database it should probably also be tagged oracle.
Questions about PL/SQL should be tagged plsql as well as oracle.
Questions specific to a particular database version may be tagged with a version tag such as oracle12c, oracle11g-r2, oracle-11g, oracle-10g or oracle-9i, but they should also be tagged oracle.
Questions applicable to 11.1.0.6 through 11.1.0.7 should be tagged both oracle-11g and oracle.
Questions applicable to 11.2.0.1 through 11.2.0.4 should be tagged both oracle-11g-r2 and oracle.
Questions applicable to other versions should be tagged as noted above.
Oracle TimesTen (in-memory database) should be tagged with timesten as well as oracle.
Oracle NoSQL (non-relational database) should be tagged with nosql as well as oracle.
