 ==== Implementation Tips ==== ==== Implementation Tips ====
 +
 +The following tips are helpful when implementing ActiveCounts in applications:​
 +
 +  * ActiveCounts works best for lower-cardinality data since that produces a reasonable set of choices to display to the user.  Criteria for high-cardinality data can be interwoven, but then it is best to just prompt for the criteria rather than display choices. ​ Consider using the [[admin:​indexing:​autocomplete:​home|AutoComplete]] feature for these criteria since it will show choices and can also show counts.
 +
 +  * The most important step in setting up ActiveCounts on a database is insuring that all statements are going to be completely optimized using Omnidex indexing. ​ It is worthwhile to obtain a [[admin:​optimization:​plans:​home|query plan]] for each query to insure that it is fully optimized.
 +
 +  * When ActiveCounts is used on an [[admin:​features:​grids:​home|Omnidex Grid]], it can help performance to present the column used as the grid's [[admin:​features:​grids:​partitions|Partition Qualifier]] first. ​ Once the Partition Qualifier has been provided, the scope of the searches is substantially reduced.
 +
 +  * When ActiveCounts is used on an [[admin:​features:​grids:​home|Omnidex Grid]], it can help performance to have [[admin:​features:​rollups:​home|Rollup Tables]] on each node, and also have Rollup Tables on a Rollup Node.
