    Types of Biological Databases

    Primary Databases

    • Also known as archival databases
    • Contain experimentally derived data like genome sequence and macromolecular structure
    • Data is not curated or modified
    • Data is uniquely identified with an accession number that never changes
    • Examples: GenBank, DDBJ, PDB, SwissProt, PIR, TrEMBL, Metacyc

    Secondary Databases

    • Contain analyzed results from primary databases
    • Data is highly curated and processed
    • Contain more valuable knowledge compared to primary databases
    • Examples: InterPro, UniProt Knowledgebase

    Hybrid Databases

    • Some databases have both primary and secondary characteristics
    • Example: UniProt accepts primary sequences derived from peptide sequencing experiments
