VistaDB Data Access Components
VistaDB Data Access Components (VistaDBDAC) is a feature-rich and high-performance library of components that provides native
connectivity to VistaDB database from Delphi for both 32-bit and 64-bit Windows platforms. VistaDBDAC-based applications connect to VistaDB database
directly through the VistaDB.Net, which is an ADO.NET provider for VistaDB. VistaDBDAC is designed to help programmers develop faster and
cleaner VistaDB database applications with no need to deploy any additional libraries. VistaDBDAC is lightweight and performs well
because it is optimized to access VistaDB databases directly without adding an OLE DB or Open Database Connectivity (ODBC) layer.
VistaDBDAC-based DB applications are easy to deploy, do not require installation of other data provider layers (such as BDE and ODBC), uses ADO.Net technologies
and that's why they can work faster than the ones based on standard Delphi data connectivity solutions.
