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 Server distributes data over a network by:

Providing application developers and system administrators with a flexible publish-and-subscribe model for marking data and stored procedures to be replicated
Managing replicated transactions while retaining transaction integrity across the network

Publish-and-Subscribe Model
Replication Server uses a publish-and-subscribe model for data replication between primary and replicate databases.
Replicated Functions
Replicating Adaptive Server stored procedures asynchronously between databases can improve performance over normal data replication by encapsulating many changes in a single replicated function. Because they are not associated with table replication definitions, replicated functions can execute stored procedures that may or may not modify data directly.
Transaction Management
Replication Server depends on data servers to provide transaction-processing services. To guarantee the integrity of distributed data, data servers must comply with transaction-processing conventions, such as atomicity and consistency.
