Most database systems have both a log in the general sense described above, and a transaction log.
Similarly, there are transaction logs in many modern database systems.
Because of storage limitations these transaction logs do not directly identify the records which were displayed.
The company keeps transaction logs to keep track of the items shoppers take home.
He had, after all, pulled my transaction logs and knew that my family ate 10 or more apples a week.
On a heavily used database, the transaction log grows rapidly.
To perform the database recovery, additional information is needed, typically contained in transaction logs.
Unlike data access, no standard exists for transaction logs.
Other challenges in using transaction logs for change data capture include:
Eliminating uncommitted changes that the database wrote to the transaction log and later rolled back.
