ADODB
TADOConnection encapsulates the ADO connection object. Use TADOConnection for connecting to ADO data stores. The connection provided by a single TADOConnection component can be shared by multiple ADO command and dataset components through their Connection properties.
TADOConnection allows you to control the attributes and conditions of a connection to a data store. Use the properties of TADOConnection to control such attributes as record locking scheme (optimistic versus pessimistic), cursor type, cursor location, isolation level, and connection time-out. Methods are also provided for implementing transactions and retrieving metadata about the database to which this component connects.
