(1 point for each correct answer. Total 10)

Each of these contains several (3)__fields__ with information about the item. For example, in a company’s employee database, these might be family name, given name, phone number and so on. One important point is that one field in each record must be (4)__unique__ - the same data must not be in any other record.

There are several ways to get data out of a database. One is simply to (8)__retrive a record__ - for example, if we want to check the data in a single record, such as an employee’s phone number. If we want to combine information from several tables or to do something with the data such as add up (9)__financial__information from several records, we can (10)__query the database__.
