Is PDB a primary or secondary database?

Question

Primary databases. In bioinformatics, and indeed in other data intensive research fields, databases are often categorised as primary or secondary (Table 2).

Is PDB a secondary database?

PDB (Berman et al., 2000) is the most comprehensive repository of structure data for biological macromolecules. The repository contains the primary structure and secondary structure information along with the atomic coordinates of a constituent atoms of biomolecule. It also contains corresponding experimental data.

What type of database is PDB?

The Protein Data Bank (PDB) is a database for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids.

Why is PDB a primary database?

All the data collected from depositors by the PDB are considered primary data. Primary data contain, in addition to the coordinates, general information required for all deposited structures and information specific to the method of structure determination.

What are primary and secondary databases?

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.
