UML deployment diagram - Real estate transactions

"A real estate transaction is the process whereby rights in a unit of property (or designated real estate) is transferred between two or more parties, e.g. in case of conveyance one party being the seller(s) and the other being the buyer(s). It can often be quite complicated due to the complexity of the property rights being transferred, the amount of money being exchanged, and government regulations. Conventions and requirements also vary considerably among different countries of the world and among smaller legal entities (jurisdictions).
In more abstract terms, a real estate transaction, like other financial transactions, causes transaction costs. To identify and possibly reduce these transaction costs, the Organization for Economic Co-operation and Development (OECD) addressed the issue through a study commissioned by the European Commission, and through a research action.
The mentioned research action ‘Modelling Real Property Transactions’ investigated methods to describe selected transactions in a formal way, to allow for comparisons across countries / jurisdictions. Descriptions were performed both using a more simple format, a Basic Use Case template, and more advanced applications of the Unified Modelling Language. Process models were compared through an ontology-based methodology, and national property transaction costs were estimated for Finland and Denmark, based on the directions of the United Nations System of National Accounts."
