The Data Application Blocks functionality in .NET is an optional .NET component that can be used to simplify certain types of common database operations. There are several limitations of this .NET component including that it only supports Microsoft SQL Server and is based on .NET DataSets. The DataSets class in .NET provides limited functionality, such as retrieving all the selected records from a query into memory for paging. For these reasons, Iron Speed Designer does not create applications that use the optional .NET Data Application Blocks functionality.
Iron Speed Designer actually surpasses the functionality provided by Data Application Blocks. It provides the same reusability and ease of use, as well as several other features that enable you to build applications much faster. Our Data Access Layer provides better control over records being retrieved as well as strongly typed data sets so you can create robust applications.
