Data integration merges data from multiple sources into a coherent data store such as a data warehouse. Data reduction can reduce data size by‚ for instance‚ aggregating‚ eliminating redundant features‚ or clustering. Data transformations (e.g.‚ normalization) may be applied‚ where data are scaled to fall within a smaller range like 0.0 to 1.0. This can improve the accuracy and efficiency of mining algorithms involving distance measurements. These techniques are not mutually exclusive; they may work

gene expression using qRT-PCR is highly influenced by the expression stability of internal control or reference genes used for transcript normalization of target genes. The use of inappropriate or unstable reference gene(s) can seriously impact the transcript quantification results leading to false inferences or misinterpretations21‚22. Accurate normalization is thus necessary for obtaining biologically meaningful expression data and hence qRT-PCR analysis greatly depends upon careful selection of
