A relational database is a type of database that organizes data into one or more tables, with each table consisting of a set of columns with unique names and each row in the table representing a unique record. The tables in a relational database are linked by common keys, allowing for easy manipulation and querying of data. Relational databases are known for their flexibility in terms of extracting data and providing multiple access points. Choice A is incorrect as it suggests limitations in data extraction. Choice B is partially correct, but does not specifically mention the two-dimensional tables and common keys that are characteristic of relational databases. Choice D is incorrect as it provides a specific application of a database rather than a description of the database itself.
