What is difference between secondary and primary database?

What are primary database give examples?

A primary database contains information of the sequence or structure alone. Examples of these include Swiss-Prot & PIR for protein sequences, GenBank & DDBJ for Genome sequences and the Protein Databank for protein structures.

What is a primary data base?

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 secondary databases examples?

Protein Databank data is stored in secondary databases. Examples include: SCOP at Cambridge University. CATH at the University College of London.Swiss-Prot and PIR for protein sequences.GenBank and DDBJ for genome sequences.Protein Databank for protein structures.Biological Databases: An Overview and Future Perspective - Enago
