The early incarnations of Delphi—immediately adopted as a tool for building database-oriented applications—could access a database only by means of the Borland Database Engine (BDE). Starting with Delphi 3, the portion of VCL related to database access was restructured to open it up to multiple database access solutions, which currently include ADO, native InterBase components, the dbExpress … 2013-09-05 In Delphi, you can build a dataset wrapping a list of objects, as in the case of the TFileData class. It's intriguing to extend this example to build a dataset that supports generic objects, which you can do thanks to the extended RTTI available in Delphi. This dataset component inherits from TMdListDataSet, as in the previous example. Students will learn the correct way to apply object oriented programming (OOP) principles to the development of Delphi applications. Students learn how to develop generic forms, objects and components, which they can reuse in multiple applications, saving development time, increasing program reliability, and improving maintainability. The early incarnations of Delphi—immediately adopted as a tool for building database-oriented applications—could access a database only by means of the Borland Database Engine (BDE).
