Final answer:
The statement is false, as metadata only describes the database structure but does not reveal the actual data contents. To know what a database contains, one must access both metadata and the data itself.
Step-by-step explanation:
The statement, 'To find out what a database contains, we just look at the metadata inside the database' is false. While metadata provides information about the structure of a database, like the tables, columns, and data types, it does not give you the actual contents or the data stored within those tables and fields. To understand what a database contains, one must look at both the metadata and the actual data.
For instance, the metadata may tell us that there is a table named 'Customers' with fields such as 'Name', 'Address', and 'Order History', but to know who the customers are and what their order history entails, we would need to query the database and retrieve the actual data.
Tested data, such as 'fire causes burns', is confirmed as true through repeated observation and attribution to a cause. This involves understanding that fire is hot and has the capacity to burn objects, including flesh. Hence, the truth of data can often be established by verifying information and evidence from multiple sources.
Therefore answer is b-false.
