Logical database structure. Based on the alleged use of the model of the information system, its position in the national economic information system and the method of creating a database, it is necessary to distinguish between several structures of the primary database, depending on different criteria for the specification of its content.
The structure of the database is subordinated to several criteria. From the point of view of the subject content, the database consists of the following elements: the primary data of the natural science and technical nature, describing the conditions and functional use of the territory (territorial-technical data); Secondary (derivatives) data on socio-economic phenomena (socio-economic data).
On a temporary basis, the database is divided into data arrays characterizing the existing state and planned changes in the conditions and functional use of the territory.
This includes the following arrays:
Real – data characterizing the current state of use of the territory;
Pro j – data characterizing the designed changes in the use of the territory;
PLAN – data characterizing the planned use and streamlining of the territory;
PROG – – data characterizing the predicted trends of the functional organization of the territory;
RE Tro – arrays of retrospective data on the use of territory conditions.
