§比 merge replication 更简单
§无冲突解决
§Pull / Update / Push 模型

| Remote Data Access provides a simpler replication model that does not require publications. It uses a simple Pull / Update / Push model that is relatively simple to code. However, there is no built-in conflict resolution, so the client will also need to implement some logic to deal with conflict errors. RDA may also result in more data being sent over the wire, as it does not deal with changes as efficiently as merge replication.
