Data Abstract 'Vinci' for .NET and Delphi is a suite including RemObjects Data Abstract for .NET and Delphi Editions:

Data Abstract allows you to create services that access any database by providing a clear separation between data-access and business-logic. Through the use of schemas and the Schema Modeler utility, it enables you to maintain a unique code base to access multiple database engines at the same time. Cross database systems are now as simple to build as single database ones.

.NET Specific Features

• The unique RemoteDataAdapter allows you to stream and update multiple data tables at once, avoiding redundant network round-trips
• Extendable Data Abstract Remote Service provides you with all the basics to access your databases and start coding your business layer immediately
• Unique and simpler driver architecture controlled by XML configuration files
• Exchange data in an optimized binary format with clients written in .NET, Mono, Delphi or Kylix and running on a large variety of platforms

Core Features

• Build scalable multi-tier cross platform database applications for .NET, Mono and Win32
• Target different database back-ends using a common code base
• Use Schema Modeler to design the interface of your data
• Leverage the new wizards and IDE enhancements to build DA applications even easier than with previous versions
• Support for a wide range of database back-ends, including Microsoft SQL Server, Oracle, DB2, Interbase/Firebird, Sybase, PostgreSQL, MySQL, SQLite, NexusDB and many more

Features

• Complete abstraction of different databases: use the same code for Microsoft SQL Server, InterBase, Oracle, MySQL, DBISAM, DB/2, etc.
• Build your applications with a "stateless" focus for maximum scalability and seamless cluster integration
• Stream data all at once, on demand, paged or any combination of those
• Re-synch fields automatically with the remote data source
• Use update rules to design complex update sequences without a single line of code
• Enhanced Business Processors give you more control on your business updates
• Cross-database autoincrement and generator-based field support
• Work with either auto-generated SQL or proprietary dialects, whenever higher performance or access to RDBMS specific features is required
• Full support for stateless Master/Detail transactional updates
• Update Rules: create complex update sequences without a single line of code
• Design your data-access layer in an innovative RAD way using the Schema Modeler
• Minimize SQL dialect differences using Data Abstract's macro processor
• Easily create your own data access driver to extend the list that comes with the product
• Support for regular expressions for client-side data-validation
• No deployment license costs

Data Abstract Schema Modeler
Data Abstract's use of Schemas enables you to maintain a unique code base to access multiple database engines at the same time, making it easy to build cross database systems.
Schemas shield both the middle-tier business logic and the client applications from the intricacies of the back-end database by defining the proper commands and data tables and mapping these to the physical data sources.
Data Abstract includes the Schema Modeler utility, which is deeply integrated with the supported IDEs, to aid you in designing and maintaining Schema definitions. Schema Modeler includes tools for creating data tables and commands from the underlying database, designing the mappings for individual data sources and defining master/detail and foreign key relationships.
