Information-logical model (ILM) of data base of the results of population census of Kyrgyzstan for 1926, 1939 and 1959 years, performed in control system of data base Access.
For creation of data base which includes the information about demographic, education and socio-professional structure of population of Kyrgyzstan in the 20-50-s years of XX century materials of the censuses for 1926, 1939 and 1959 were used. Information-logical model (ILM) of database performed in Access program is the data of results of censuses in the form of totality of information objects and links between them.
Information object – is an informative description of some nature of a real object, process, fact or event. Information object is based on totality of logical interrelated properties which represent the qualitative and quantitative characteristics of structure of population on results of censuses for 1926, 1939 and 1959. (sex, age, profession, family status and so on).
Information objects are distinguished basing on description of demographic, educational and socio-professional structure of the results of censuses for 1926, 1939 and 1959 by means of determination of the functional dependences between the properties. The totality of properties of information object should meet the requirements of normalization. Each information object should be named with own unique name. Upon graphical representation of the model of data each information object should be represented by a rectangle with identification of its name and identification key.
During the process of development of the models of data we should pick out information objects, I mean the indicators of qualitative conditions of population (sex, age, family status), as well as structure of distribution with indication of regions, provinces, which should comply with requirements of data normalization and determine the links between them. This will let to create a relational database without duplicating, it means that population of the same age or from the same region will not be put in database twice; in this way it ensures a single input of data at initial loading and further updating. This database performed in Access program ensures the integrity of data upon inserting of amendments, in other words, when indices increase in territorial and structural way, the initially introduced information can change its initial value in respective parameters depending on new data.
The results of creation a source-oriented database performed in Access program firstly makes easy search of information and it makes it open for public use as well; secondly it allows to make a request on needed parameters of demographic structure of population. All this leads to activation of scientific researches, and makes easy access to such kind of complex mass source as materials on demographic statistics.
