Chapter 1: Introducing DirectConnect

Before Enterprise Connect Data Access 12.5, its options were sold as individual DirectConnect products named “DirectConnect for [target].” Other than in the installer, you will see the name “DirectConnect” used in the software and in documents. As such, this document uses the old product name except for the title page. Old and current option names are as follows:
