Framework for Client-Server Distributed Database System for Population Census

With the great awareness of the growing need for information on population dynamics, a comprehensive study of demography in Nigeria with particular reference to population census and projection is a desirable venture. Existing sources of demographic data in Nigeria is restricted to census, surveys, and special inquires. There are no national systems of registration of vital events at the levels of completeness sufficient to provide useful demographic information. The time taken to summarize, analyze, and publish census results are usually very long. This observable problem can be associated with the conventional approach to census collection taken in Nigeria. In this study, an attempt is made to design a framework for a distributed database system for population census collection in Nigeria. This framework includes a model for the analysis of demographic parameters of respondents in a study area. Basically, the demographic parameter or population variables are: relation to head of household, sex, age, disability, home local government area, home place, address, literacy, educational qualifications, work status, type of employment, sector of employment, marital status, and statistics of marriage. Microsoft Visual Basic® and SQL is considered in the design. (
