Buildstats and buildvisit

The buildstats utility updates database statistics. You can use buildstats for all of the Recommendation engines except for the Item Affinity Engine.

When you install the LikeMinds utilities, the installer sets buildstats to run once a day, at 3:30 a.m. This is because the best time to run buildstats is daily, at a time when the LikeMinds server receives relatively little use. The buildstats utility connects directly to the LikeMinds database and processes the transactional or ratings data that is constantly being written to the LikeMinds database. Because this utility does not consume many resources, it is typically installed on the same machine as the LikeMinds server. buildstats performs a number of data analysis functions on the information in the LikeMinds database and persistently writes out the results into the LikeMinds schema. However, the functionality of this and the number of functions to test differ depending on the type of LikeMinds engines in use. If both a Preference and ClickStream are in use, buildstats will, by default, analyze both the ratings and the transactional data.

For ratings data, buildstats writes to the following fields in the Lps_Item_Data table:

For transactional data, buildstats writes to these fields in Lps_User_Trx:
