• Integration with Visual Studio: Use Server Explorer to browse your Oracle schema and launch one of the many integrated Oracle designers and wizards to create and alter schema objects. Use Microsoft Query Designer to visually design queries.
• Automatic .NET Code Generation: Use the Visual Studio Datasources Window, the Dataset Designer, and the TableAdapter Configuration Wizard to drag and drop and automatically generate .NET code.
• Easy ASP.NET Web Development: If you're an ASP.NET web developer, ODT makes it easy to generate ASP.NET web applications with very little coding required.
• Powerful Application Tuning Tools: New in beta! Tune your .NET application's use of Oracle Database via a single click of a button with Oracle Performance Analyzer. The database is then monitored under load and recommendations are made, such as modifications to SQL or adding an index on a table. Many tuning recommendations can be applied automatically by simply clicking a button.
• SQL Script Lifecycle with Source Control Integration: Generate SQL scripts for Oracle schema objects that your .NET application uses, manage them in an Oracle Database Project, check them into source control, edit the scripts in the Oracle SQL Editor, and execute them with a built in SQL*Plus execution engine.
• PL/SQL Editor and Debugger: The fully integrated PL/SQL Editor and Debugger allows you to leverage all of your favorite Visual Studio debugging features from within PL/SQL code. You can even seamlessly step from your .NET code into your PL/SQL stored procedure code and back out again!
• NET Stored Procedure Deployment: The .NET Deployment Wizard makes it easy to deploy .NET stored procedures and functions into Oracle Database.
• Integrated Online Help System: The integrated context sensitive online help, including the Oracle SQL and PL/SQL Users Guides puts the Oracle documentation at your fingertips.

• Oracle Advanced Queuing (AQ) Designers: New in beta! Create, modify and administer your Queues and Queue Tables.
• User-Defined Types (UDTs): Create UDTs in Oracle with multiple new designers. A powerful UDT Custom Class code generation wizard makes using UDTs from .NET code easy and fast. An application can be rapidly created that utilizes UDTs with almost no coding required.
• Import Table Wizard: This new wizard makes it easy to move tables and their data from external datasources such as Microsoft SQL Server, Microsoft Access and Excel spreadsheets into Oracle Database.
• Data Editing, Stored Procedure Testing, Adhoc SQL Execution: When testing your .NET application you can use the Oracle Data Window to insert and update Oracle data. There's also a testbed for testing stored procedures and an Oracle Query Window for executing any SQL statement you choose.
