What is difference between primary and secondary database?

Question

Primary databases store and make data available to the public, acting as repositories. Secondary databases make use of publicly available sequence data in primary databases to to provide layers of information to DNA or protein sequence data.

What is the primary database?

Primary databases are populated with experimentally derived data such as nucleotide sequence, protein sequence or macromolecular structure. Experimental results are submitted directly into the database by researchers, and the data are essentially archival in nature.

What are primary database give examples?

Primary databases contain information for sequence or structure only. Examples of primary biological databases include: Swiss-Prot and PIR for protein sequences. GenBank and DDBJ for genome sequences.

What is the difference between primary data and secondary data point out the limitations of secondary data?

Primary data is the type of data that is collected by researchers directly from main sources while secondary data is the data that has already been collected through primary sources and made readily available for researchers to use for their own research.

Are databases primary or secondary?

Primary: original objects or documents with first-hand information or raw material. Secondary: sources that analyze, interpret, or draw conclusion from a primary source. Tertiary: sources that index, organize, or compile other sources.
