Overview

The db unit provides the basis for all database access mechanisms. It introduces abstract classes, on which all database access mechanisms are based: TDataset representing a set of records from a database, TField which represents the contents of a field in a record, TDatasource which acts as an event distributor on behalf of a dataset and TParams which can be used to parameterize queries. The databases connections themselves are abstracted in the TDatabase class.
