OLEDB Direct Components Suite is a set of VCL-style components for Delphi 4 - 7 and C++ Builder 4 - 6 that allow database access using OLEDB interfaces (these interfaces ADO uses internally). It is designed for extremely fast data access and it provides a possibility to use database services that are additionally implemented by OLEDB provider (such as bulk rowsets in MS SQL Server OLEDB provider). It should be used if you need to work with very large amount of data. For example, with OLEDB Direct you will be able to insert 1 000 000 rows in MS SQL Server in 10 seconds on modern computer (< 1 minute on most computers).
