General Features

• Build scalable cross-platform multi-tier database solutions for .NET, Mono, 32- and 64-bit Windows and Linux.
• Target different database layouts or systems using a common code base.
• Use the RAD Schema Modeler to model the structure of your data as it will be exposed to the middle- and client-tier. 
• Absolutely no deployment license fees.
• Full support for C#, Oxygene, Visual Basic .NET (.NET Edition) and Object Pascal (Delphi Edition).
• Support for Silverlight web clients.

Library Features

• Complete abstraction of different databases types: write one set of code and target any supported database backend type. 
• Complete abstraction of different database layouts: have a single middle-tier server target different database designs, for example a legacy database and a new, well-designed replacement database.
• Build your applications with a "stateless" focus for maximum scalability and seamless cluster integration.
• Easily create your own data access drivers to extend the list of databases supported out of the box.
• Support for regular expressions for client-side data-validation.
• Strongly Typed Data Tables allow you to access your tables from code using fully object-oriented code. 
• Business Helper Classes allow you to encapsulate business logic and rules. 
• Let Data Abstract auto-generate all SQL code on the fly - or provide manually written SQL code to cover special requirements.
• Minimize SQL dialect differences in shared SQL code using Data Abstract's macro processor.
• Fully reusable Reconcile Dialog architecture, allowing you to provide end-users with feedback about failed updates. 
• High performance memory data table component for client-side data storage (Delphi/FPC only; .NET leverages the existing DataSet class). 
• Rich Business Rules Scripting using RemObjects Pascal Script. (Delphi Only)
• 100% native and platform-specific implementations, designed from the ground up for the individual platforms.
• Full source code is provided, allowing you to make changes and rebuild the library, if needed.

Data Access Features

• Stream data all at once, on demand, paged or any combination of these.
• Re-synch fields with the remote data source automatically.
• Enhanced Business Processors give you more control on your business updates.
• Cross-database AutoInc and generator support for integer-based primary and foreign keys.
• Full support for stateless Master/Detail transactional updates.
• Extensive set of cross-database data types including new XML, GUID and Decimal types.
• Leverage new DynamicWhere and DynamicSelect features to vertically or horizontally filter the subsets of data retrieved by the client. 
• Reduced Delta mode to optimize network traffic by only sending key and changed fields for updates.
• define Union Tabless in your schema and transparently publish them to clients as one coherent data table.
• leverage DA SQL and DA LINQ to flexibly query data from the client (.NET only)

Schema Modeler Features

• Design your data-access layer in an innovative RAD way using the Schema Modeler. 
• Use the Data Explorer for a live view of the underlying database system.
• Create and define data tables and commands via drag and drop.
• Use update rules to design complex update sequences without a single line of code. 
• Let the Validation Wizard ensure that your schema 100% matches the underlying database.
• Define Column Mappings to abstract differences in database layout. 

IDE Integration Features

• Full integration with the supported IDEs.
• Project Templates and extensive New Project Wizard to help start new projects .
• Project integration of Schema Modeler with the IDE, allowing you to edit your service definitions within the IDE's project system (.NET) or form designer (Delphi).
• New Welcome Page displayed after first install to assist new users with getting acquainted with the product.
