Secondary storage is commonly referred to as hard disk. Secondary data is collected from published sources and research conducted by other people. Biological databases are stores of biological information. Primary data is harder to obtain, but is tailored specifically to your study and therefore more important as a source than secondary data. Summary of Primary vs. Methods of Data Collection- Primary and Secondary Data . What is the exact differences between Primary index, Secondary index and clustered index. Extra precautions are not required. For example, UniProt accepts primary sequences derived from peptide sequencing experiments. By contrast, secondary databases comprise data derived from the results of analysing primary data. Data from an experiment is a primary source. There are two main classes of databases:DNA (nucleotide) databases and protein databases. %PDF-1.6 %���� Secondary data is the data that have been already collected for another purpose but has some relevance to your current research needs. %%EOF Both primary and secondary data are crucial in research.

Secondary index: A Secondary index is an index that is not a primary index and may have duplicates. As opposed to secondary data which is easily accessible but are not pure as they have undergone through many statistical treatment. 5.
