About This Manual

Subject	This book describes all aspects of the SQL Remote data replication system
	for mobile computing, which enables sharing of data between a single
	Adaptive Server Anywhere or Adaptive Server Enterprise database and
	many Adaptive Server Anywhere databases using an indirect link such as
	e-mail or ﬁle transfer.
Audience	This book is for users of Adaptive Server Anywhere and Adaptive Server
	Enterprise who wish to add SQL Remote replication to their information
	systems.
Before you begin	☞ For a comparison of SQL Remote with other replication technologies,
	see “ Introducing Replication Technologies” [Introducing SQL Anywhere
	Studio, page 21].
