Oracle Developer Tools for Visual Studio

• 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 minimal coding required.
• Powerful Application Tuning Tools: New! Use Oracle Performance Analyzer to tune your .NET application's use of Oracle Database via a single click of a button. The database is then monitored under load and recommendations are made, such as modifications to SQL or adding an index on a table. You can also tune Ad-hoc SQL statements in Query Window with SQL Tuning Advisor. ( Watch a video demonstration)
• 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.
• Manage Users, Roles and Privileges: New! Create Users and Roles using graphical designers. Assign privileges to the roles and assign roles to users. View the Users and Roles in Server Explorer.
• Oracle Advanced Queuing (AQ) Designers: New! 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.
• Import Table Wizard: This wizard makes it easy to import tables and their data from Oracle databases, or from external datasources such as Microsoft SQL Server, Microsoft Access and Excel spreadsheets.
• 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.
