Relational Queries

Definition

Relational queries are structured requests used to retrieve and manipulate data from relational databases, which organize data into tables with predefined relationships. These queries, typically written in SQL, allow users to specify criteria for selecting, joining, and aggregating data. While blockchains are not traditional relational databases, the concept of querying and analyzing structured data within them is relevant for analytics. It is fundamental to data retrieval in many traditional systems.
