In OpenMetadata we have hierarchal team structure with `teamType` that can be `Organization`, `Business Unit`, `Division`, `Department`, and `Group` (default team type).
-`Organization` is the root team in the hierarchy. _It can't have a parent_. It can have children of type `Business Unit`, `Division`, `Department`, `Group` along with `Users` directly as children (who are without teams).
-`BusinessUnit` is the next level of the team in the hierarchy. It can have `Business Unit`, `Division`, `Department`, and `Group` as children. It can only have ** one parent ** either of type `Organization`, or `Business Unit`.
-`Division` is the next level of the team in the hierarchy below `Business Unit`. It can have `Division`, `Department`, and `Group` as children. It can only have ** one parent ** of type `Organization`, `Business Unit`, or `Division`.
-`Department` is the next level of the team in the hierarchy below `Division`. It can have `Department` and `Group` as children. It can have `Organization`, `Business Unit`, `Division`, or `Department` as parents. ** It can have multiple parents **.
-`Group` is the last level of the team in the hierarchy. It can have only `Users` as children and not any other teams. It can have all the team types as parents. ** It can have multiple parents **.
