*    Table and column mapping support for the BdpDataAdpater has been added.


Data Explorer Updates

Numerous enhancements have been made to the Data Explorer to help you design and develop BDP.NET database applications:

*    The Data Explorer supports data migration from one data provider to another. The context menu for tables includes Migrate Data, Copy Table, and Paste Table commands, which let you copy a table of data from one provider and paste it as a new table into another provider.

*    Drag-and-drop stored procedures—stored procedures can be dragged from a provider in the Data Explorer onto a form in the Designer. This adds and configures a BdpConnection and a BdpCommand component and automatically populates the acquired stored procedure parameters.

*    Metadata services—the Data Explorer provides a variety of metadata services that allow you to view and modify your database schema. Using the context menu in the Data Explorer, you can retrieve data from a table for viewing, add a new table, drop an existing table, or alter the data structure of an existing table. You can retrieve data associated with a view. You can also view and modify (input only) the parameters for a stored procedure, and execute the stored procedure.


VCL for .NET Database Support Updates

Many updates and additions have been made to enhance database support for VCL applications for .NET:

*    BDE for .NET—BDE for .NET has been updated to provide dynamic loading of DLLs without specifying a path, to improve performance for handling BLOBs, and to include classes that were previously missing in the .NET implementation ( TUpdateSQL , TNestedTable , and TStoredProc ).

*    dbExpress—the updates for dbExpress include core driver enhancements, metadata improvements for schema name discovery and other bug fixes, TSimpleDataSet ported for .NET, enhanced Command Text Editor, TSQLStoredProc performance improvements, and a new TDataSet component that consumes IListSource.

*    dbGo—dbGo has been ported to .NET to support migration of ADO database applications to the .NET framework.

*    DataSnap—the following DataSnap components have been ported to .NET: TLocalConnection , TConnectionBroker , and TSharedConnection .


Additional Database Suppport Updates

The following updates simplify database application development:

*    Typed dataset support improvements—typed datasets now compile to standalone assemblies without having to compile the entire project. Typed datasets support datasets from Web Services. Access to the Relation Collection Editor and the Table Collection Editor has been added to to the Program Manager context menu to simplify modifying a typed dataset. Easy access has been provided for the .NET DataSet Properties dialog box for viewing the structure, properties, and constraints for a typed dataset.

*    The Object Inspector provides access to a connection string editor for the ConnectionString property for SQLConnection components.


Visual Component Library (VCL)

*    Many of the Win32 VCL components have been updated to support the .NET framework. These include WebSnap and IntraWeb.


Delphi
Language Enhancements

*    Delphi has a new for-in-do statement that you can use to iterate over containers. See the Delphi Language Guide topic Declarations and Statements for more information.

*    The compiler now supports function and procedure inlining. See the Delphi Language Guide topic Calling Procedures and Functions for more information.

*    The Delphi language has been expanded to include alphabetic and alphanumeric Unicode characters in identifiers. Note: Unicode characters are not allowed in identifiers in published sections of classes, or in types used by published members.

*    The language now supports the aggregation of multiple units within a namespace. See the topic Using Namespaces with Delphi for more information.

*    The Delphi for .NET compiler now supports dynamically allocated multi-dimensional arrays. See the Delphi Language Guide topic Structured Types for more information.
