Difference between LemonTree Inconsistency Check and Enterprise Architect Integrity Check

Both Enterprise Architect and LemonTree offer features to check a model for irregularities:

• In LemonTree, the Integrity Check is performed automatically before every compare/merge
• Enterprise Architect allows for manually checking the integrity of a model (https://sparxsystems.com/enterprise_architect_user_guide/15.1/model_repository/checkingdataintegrity.html) 

Each tool applies it's own separate ruleset for determining these irregularities.

As such, it is possible that one tool detects no irregularities in a given model, while multiple are detected by the other one. For details on the irregularities detected by LemonTree, please refer to this page: Description of Inconsistencies
