rule of thumb and should be evaluated on case by case base. |
When the size is small, then you can easily create and maintain the data inside your model. When the numbers increase, you usually want to place the maintenance outside your application. The AQ_CsvConnectivityService, Data rules and CSV wizard and Web Services create instances in your profile for each possible value. With a large number of values this may lead to performance problems (think of long running COLLECT statements). For large numbers we advice to use External Value lists. Such a long value list can be easily searched by the end user using Valuelistsearch Presentation style.
