The relational model organizes data into tables, which are made up of rows and columns. Each row represents a single entity, such as a customer or product, and each column represents an attribute of that entity, such as the customer&#8217;s name or the product&#8217;s price.<\/p>\n<p>Tables are related to each other through common attributes. For example, a customer table might be related to an order table through the customer ID attribute. This means that each customer in the customer table has a corresponding record in the order table.<\/p>\n<p>RDBMSs are designed to be efficient and scalable. They are often used to store large amounts of data, such as customer information, product inventory, or financial records.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li><strong>A. Tables<\/strong><\/li>\n<\/ul>\n<p>Tables are the basic unit of storage in a relational database. They are made up of rows and columns. Each row represents a single entity, such as a customer or product, and each column represents an attribute of that entity, such as the customer&#8217;s name or the product&#8217;s price.<\/p>\n<ul>\n<li><strong>B. Relations<\/strong><\/li>\n<\/ul>\n<p>A relation is a mathematical concept that describes a set of ordered pairs. In the context of a relational database, a relation is a table.<\/p>\n<ul>\n<li><strong>C. Tuple<\/strong><\/li>\n<\/ul>\n<p>A tuple is a row in a table. It is made up of a set of values, one for each column in the table.<\/p>\n<ul>\n<li><strong>E.
