The conceptual data model can be defined as what people think and shall contain all the data necessary to achieve the goals of the system, as well as shall be directly translated into the logical and physical schema of the database (Anwar 2009). The necessity of developing a scientifically based information model of land accounting, the use of which is necessary for solving problems of urban planning and design is justified. The information model will form the basis of the information system necessary to ensure the collection, accumulation and processing of initial data for urban planning analysis, solving scientific problems and justifying practical decisions. Figure 2 presents a model of the land accounting information database, which uses symbols to represent three different types of information. A logical model is a combination of all the data entities and attributes that were entered in the GIS systems. The information model includes a description of how data is stored in the computer and how information is presented, building indexes, alternative resolution, and physical storage objects such as tables and maps.

The databases of parking guidance system include traffic information database, parking management database, map database, etc. Generally, the database design process consists of four phases: requirements elicitation, conceptual schema design, logical schema design, and physical schema design. This paper only presents the database design process for parking management.
