ABSTRACT
Biomedical data warehouse is the central management system having pool of DNA/RNA protein datasets where protein identification, matching and searching are important operations. The traditional data warehouse was designed in such a manner that it can efficiently manage transactional data which is highly dominated by numerical information where as in biomedical data warehouse textual and non transactional information is encountered. The dataset which contains text data is accessed over the network on the daily basis and performance issue arises. The objective of this paper is to propose an indexing technique based on time complexity and index space complexity for data warehouse used in application of biomedical field. The performance evaluation of three data warehouse queries is focused in this paper by comparing techniques used mostly with FULL TEXT indexing technique and to observe the results of variable size dataset with respect to time and space complexity.
