The DataPipeline class in ReportBuilder provides an open, extensible architecture for natively accessing data stored in any format. ReportBuilder includes a BDEPipeline for accessing data via Delphi's TDataSource, a DBPipeline for accessing TDataSet descendants that do not require the BDE, a TextPipeline for accessing data stored in ASCII text files, and a JITPipeline for accessing data based on custom event-handlers. Additional data pipelines can be developed to natively access data stored in proprietary formats or objects.
