Chapter 2 Information Liquidity Model Basics
Replication is the process where the transactions performed on one database (called the source database) are propagated asynchronously to one or more target databases or replication engines in a serialized manner.
A transaction is an atomic unit of processing on the source database.
Transaction-based replication means that either an entire transaction is replicated to a specific target database, or nothing at all is replicated.
Asynchronous means that transactions are replicated after they have been committed on the source database.
Serialized means that transactions, as well as the operations within the transactions, are replicated in the same order in which they were applied. If the transactions, or even the operations within one transaction, are replicated to a target database in a different order from how they were applied on the source database, serious inconsistencies between the source and target databases may result.
