Introduction

Use Replication Server® to create and maintain distributed data applications.

• Centralized and Distributed Database Systems
  Changes in the corporate environment toward decentralized operations have prompted organizations to move toward distributed database systems.
• Advantages of Replicating Data
  The performance and availability problems associated with remote database access can be solved by replicating the data from its source database to a local database. Replication Server provides a cost-effective, fault-tolerant system for replicating data.
• Data Distribution with Replication Server
  Replication Server replicates transactions—incremental changes instead of data copies—and stored procedure invocations, rather than the stored procedures themselves, providing a high-performance distributed data environment while maintaining data integrity
• Replication System Components
  Replication Server has an open architecture that allows you to build a replication system from existing systems and applications and add to it as your organization grows and changes.
• Replication Management Solutions
  Replication Server offers two-tier and three-tier management solutions to support different replication environments.
• Replication System Components
  Replication Server, Replication Agent, and Adaptive Server use C/SI to communicate over a network. In addition, Replication Server uses routes and connections to send messages to other Replication Servers and databases.
• Master Database Replication
  The master database controls the operation of Adaptive Server and stores information about every user database and associated database devices.
• Non-ASE Data Server Support
  The open architecture of Replication Server supports non-ASE data servers in replication systems.
• Replication Server Security
  Replication Server security includes password-protected login names and a permission system based on the grant and revoke commands.
