Describe the structure of a database. When is a database considered a relational database?

What will be an ideal response?

Databases are large files that store important information in the form of tables. A table organizes information into a list. Within the list, the set of information about a particular item is called a record. For example, in a list of customer mailing addresses, a single record would contain a customer's first name, last name, street address, city, state, and zip code. The various categories of information within a record are called fields. For example, in our customer mailing address example, one field contains the city information, one contains the state information, and so on.Most databases consist of dozens or hundreds of tables that store information used by applications. For example, accounting software typically stores financial data within a database. In large databases, information within certain tables can be related to information within other tables in the same database. These databases are called relational databases, and the tables within are usually linked by a common field.
