A systematic approach to generate query model for DNA

The deoxyribonucleic acid (dna) molecular structure contains lot of important information which is unique in every human being. storage,processing and manipulation of dna's structural information in a computer system are still in its infancy. for perfect handling of such type of data,we need a database management system. our research work described in this paper arose from the observation that existing data models and query languages (and the database systems realizing them) do not offer sufficient support for the modelling of dna structure. this is an attempt to find a good representation for dna structure and solution to the problem representation of dna is given in form of an object oriented data model by using the idea of bar code technology. it is shown that the chemical structure of dna can be encoded in bar code which makes storage of dna structure a lot simpler than existing approaches. in the end we have proposed a query language (dna-ql) to store,retrieve and manipulate the biological data. to achieve these objectives,we intend to propose a data model to model dna structures in a uniform fashion. development of this type of model and query language enables us the development of dbms for storing biological structural information of dna. copyright 2015 zoological society of pakistan.
