Equivalent functionality as SQL Developer
JDBC-ODBC bridge can be used as native driver for supported databases
JTDS 1.2 driver (the one used in SQL Developer) can be used to import from MS SQL server in addition to native drivers from Microsoft

Allow a list of supported native database types to be extended - PL/SQL data types or types like  LCR$_ROW_RECORD can be added through this functionality

Add a design level domain to a current open design

Functionality "Create Subview with Neighbors" in context menu for table in browser

Management of overlapping and folded foreign keys at entity level in Entity dialog. - used in engineering to relational model

Import using third party JDBC drivers - view definition will be imported if database supports INFORMATION_SCHEMA.VIEWS view

Language support is the same as SQL Developer and has been translated into French, German, Italian, Spanish, Brazilian Portuguese, Japanese, Korean,Simplified Chinese,Traditional Chinese

Improvements in loading and closing of large designs

Grants for Packages, Functions, Directories, Types, Collections and External tables
