Chapter 10 Working with Replication Server
The main components of the Replication Server engine are modeled in PowerDesigner as followed:
| Replication Server | PowerDesigner |
|---|---|
| Replication server– coordinates the data replication activities for the local data servers and exchanges data with Replication servers at other sites. | Replication process with Replication Server type (see RepServer Servers). |
| Connection– specifies a message stream between a Replication server and a database. | Data connection (see RepServer Connections). |
| Route – specifies a one-way message stream that sends requests from one Replication server to another Replication server. | Process connection (Defining a route) |
| Replication definition – specifies the structure of the table and names the database that contains the primary copy of the table. | Article (see RepServer Replication Definitions). |
| Article – specifies a replication definition extension for tables or stored procedures that allow you to assign table or function replication definitions in a publication. | Article (see Replication Server Articles). |
| Publication – specifies the tables and columns to replicate data | Publication (see RepServer Publications). |
| Database replication definition – Describes a set of database objects to which you can subscribe. | Publication (see RepServer Database Replication Definitions). |
| Subscription – specifies the publication to use to replicate objects. | Subscription (see RepServer Subscriptions). |
| Function replication definition – specifies information about to stored procedure to replicate | Procedure (see RepServer Function Replication Definitions ). |
| Function string – specifies a template used by the Replication server to generate a command the data server can interpret as a transaction-control directive or as a data-modification instruction. | Event script (see RepServer Function Strings). |
| User – specifies a user name and password to connect to a Replication server. | User (see RepServer Users). |
| Logical Connection – specifies the active and standby databases in a warm standby application. | Data connection group (see RepServer Logical Connections). |
