Why do we need secondary database in bioinformatics?

What is secondary database in bioinformatics?

Secondary databases contain information derived from primary sequence data which are in the form of regular expressions (patterns), Fingerprints, profiles blocks or Hidden Markov Models. The type of information stored in each of the secondary databases is different.

What is the importance of databases in bioinformatics?

Abstract. Biological databases play a central role in bioinformatics. They offer scientists the opportunity to access a wide variety of biologically relevant data, including the genomic sequences of an increasingly broad range of organisms.

Why secondary databases of protein structures are important?

In addition, secondary databases derived from experimental databases are also widely available. These databases reorganize and annotate the data or provide predictions. The use of multiple databases often helps researchers understand evolution, structure, and function of a protein.

What is difference between primary and secondary database?

In DB, the database that contains your data is called a primary database. A database that provides an alternative set of keys to access that data is called a secondary database. In a secondary database, the keys are your alternative (or secondary) index, and the data corresponds to a primary record's key.
