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. We call this field the (5) primary key. It can be a staff ID number, for example, but it can't be a given name because many people have the same given name. Another type of object is a(n) (6) form which is used for entering data into tables. A third object type is a(n) (7) report.

Grammar box: By + ing in language We can find the total number of hours We can use by + -ing to express how to by querying the database. do things By running a report, we can print a list of customers. The phrase "by doing something" is grammatically correct and can be used in written English. You can use this phrase to indicate the means or method by which an action was accomplished. For example: "Tom achieved success by doing something he loved." By meaning ‘how to do something’ We use by + -ing form to describe how to do something: Ex: By pressing this button, you turn on the alarm system. Then by entering the code 0089, you can turn it off again. We use by + noun to describe how someone travels or communicates, or how things are processed: Ex: I’ll send it by email; I can send it by post as well if you wish. Can I pay by credit card? We say by car, by bus, by plane, etc. but if there is a determiner (e.g. a/an, the, some, my, his) before the noun, we say in or on. Practical work.
