Tutorial: Using dbExpress Delegate Drivers

Go Up to Tutorials

Delegate drivers are useful for connection pooling, driver profiling, tracing, and auditing. Use delegate drivers to build a stack of drivers, where the bottom driver communicates with the database, and the drivers on top are used for tracing, connection pooling, and auditing.

This tutorial shows how to pool and trace a connection for a dbExpress application.

Note: You must have at least one database, such as InterBase, installed and operational.
