User Data Tables that Vary in Size

DHLOG-Model history activity logging. When logging is enabled, archive this table frequently to keep it small.
DHOBJ-Object history activity logging. When logging is enabled, archive this table frequently to keep it small.
DTXT-Bulk of data is descriptions inside model. This table may grow as the use of descriptions increases.

You can disable DHLOG and DHOBJ for each model by using Host Encyclopedia option 1.3.13.4.
