# Data Explorer

It is important to understand that Data Explorers process ALL records returned from the database, even if they are not displayed. For example, FK ref info strings, BS calls, SS calls, Inhibit Row in Explorers - all can cause per-row processing even if they are not displayed.

Data Explorers are rendered using JavaScript. They are not designed to display many records, and trying to do so will result in possibly unacceptable performance. DO: Consider limiting the results returned and asking Users to add additional filter criteria to narrow down the results. DON'T: Don't try to display hundreds of records.
