Final answer:
Yes, it is common for large databases to have more than thirty separate tables. By organizing the data into separate tables, it allows for better organization, easier management, and efficient querying of the data.
Step-by-step explanation:
Yes, it is common for large databases to have more than thirty separate tables. In fact, it is not uncommon for databases to have hundreds or even thousands of tables, depending on the complexity of the data being stored and the specific needs of the system. Each table in a database represents a specific set of related data, and by organizing the data into separate tables, it allows for better organization, easier management, and efficient querying of the data. For example, let's say we have a database for an online retail store. We might have separate tables for customers, products, orders, and payments. By separating the data into these individual tables, it allows for more flexibility when retrieving information. We can easily retrieve customer information without having to also load all the product or order data. One advantage of having more than thirty separate tables in a large database is that it allows for better scalability and modular development. As the system grows and evolves, new tables can be added without affecting the existing tables, making it easier to manage and maintain the database.
