Querying

Definition

Querying refers to the process of requesting information from a database by specifying certain criteria. In the context of protein sequence databases, querying allows researchers to extract specific protein sequences, annotations, or related data from large repositories, making it easier to find relevant information for their studies. This process is crucial for bioinformatics as it enables the analysis of protein functions, structures, and interactions based on the available data.
