Logical Log Files In some DBMS's logical log files are maintained for database recovery as compared to before and after log files. I think the main difference is that in logical log file, you just record the database operations rather then the copy of the data before or after the database operation. Can anyone point out to some good reference dicussing pros and cons of logical log files. I will really apprciate any kind of information. Thanks Harvi Sachar AT&T Bell Labs
