jConnect is the Sybase high-performance JDBC driver. jConnect is both:
A net-protocol/all-Java driver within a three-tier environment, and
A native-protocol/all-Java driver within a two-tier environment.
The protocol used by jConnect is TDS 5.0 (Tabular Data Stream™, version 5), the native protocol for Adaptive Server Enterprise and Open Server™ applications. jConnect implements the JDBC standard to provide optimal connectivity to the complete family of Sybase products, allowing access to over 25 enterprise and legacy systems, including:
Adaptive Server Enterprise
SQL Anywhere®
Sybase® IQ
Replication Server®
DirectConnect™
In addition, jConnect for JDBC can access Oracle, AS/400, and other data sources using Sybase DirectConnect.
In some instances, the jConnect implementation of JDBC deviates from the JDBC specifications. For more information, see “Restrictions on and interpretations of JDBC standards”.
