Final answer:
Relational databases connect information across multiple tables efficiently through primary and foreign keys, enabling powerful data retrieval and analysis.
Explanation:
Relational databases are a database model that relates information across multiple tables through primary and foreign keys. In a relational database, data is separated into subject-based tables, allowing for efficient data retrieval and analysis through queries.
One of the main advantages of a relational database is the ability to maintain and edit tables separately until they need to be related for a specific query or analysis, enhancing processing efficiency within the database.
Queries in a relational database allow users to draw information from multiple tables based on defined search conditions, providing more power and flexibility compared to simple searches within a single table.
