The basic primary copy model allows you to replicate data from a primary database to destination databases. This model is well suited to decision-support applications, although low-volume transaction-processing applications can update primary data remotely, either directly over the WAN or through request functions (replicated stored procedures). Primary data that is updated from remote sites can then be replicated back to subscribing sites.
You can implement the basic primary copy model by using any or all of the following:
Table replication definitions
Applied functions
Request functions
This section provides basic examples for using table replication definitions and applied functions. For examples of request functions and other, more advanced uses of the primary copy model, see “Model variations and strategies”.
