Abstract
The basic sources of information pertaining to real estate valuation include: the real property register and the landand buildings cadastre which are located in different institutions. As a result, gathering all the documentation required for a real estate evaluation becomes a time-consuming task. In order to be effective an appraiser requires fast access to information. In the paper the author proposes 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. At the present time, a convenient database solution containing geographical information utilizes the geodatabase model. The geodatabase is a new object-oriented data model, which stores data in a relational database. The objects stored within the geodatabase mostly refer to the same objects existing in the real world; for example: parcels, buildings, etc. An important aspect of the geodatabase is the user.s ability to optionally create a custom feature instead of dots and lines. An .object view. of the data allows the users to focus their efforts on building a geographical data model and hides most of the geodatabase.s physical structure. In addition, it can display the geographical data in three ways: vector data, descriptive data and raster data. Geodatabase.s big advantage is its accessibility, allowing its users to easily and freely create, access, and manipulate geographical data. Accessing the geodatabase requires no specific software . the technology and documentation easily support direct access from other products and systems. At present, CASE tools (Computer Aided Software Engineering) are the most popular software used in database creation utilizing the object-oriented modeling method. Additional CASE tools let the user build a database model using the Unified Modeling Language. Microsoft Office Visio 2003, one of the most popular CASE tools, was used to prepare the schema of the UML database. The final step in geodatabase creation included automatic generation of the database structure using the ArcGIS system (ESRI).
