Conceptual modelling of real estates for the prposes of mass appraisal
Debinska, Ewa & Piotr Cichocinski
Legislative works are taking place in Poland on elaboration of detailed regulations concerning mass appraisal. The approval of them will cause necessity of valuation of several million properties. The basic sources of information pertaining to real estate valuation include: the real property register and the land and buildings cadastre which are located in different institutions. As a result, gathering all the documentation required for a real estate valuation becomes a timeconsuming task. In the paper the authors propose a database model for real estate valuation. It contains information regarding types of real estate such as parcels, buildings and dwelling areas. We currently live in a computerized society, therefore the planned database must not only consist of descriptive attributes, but also contain information regarding their locations and shapes. Such a database, containing geographical information, that distinguishes it from among other databases, can be named a geodatabase. The introduction of the geodatabase model allows the application of the methods of designing relational databases, including CASE tools, also for geographic information.
