Database

A database consists of one or more than one tables in which data are stored and managed.Inside the database, tables work together with queries and reports to produce the requiredoutput.

Table

A table consists of records, which is the data about a particular subject. E.g. a databasemight contain a table of data on students (names, student ID, address, telephone number)

Field

A field is a single unit of data, such as a person's name or an address or even a telephonenumber. A field generally appears as a single column in a table.

Primary Key field

A primary key field is one that uniquely identifies each record in a table. Your HKIDnumber is an everyday example of a primary key field, because it uniquely identifies youon the government's database.

Form

A form is an interface, which display data or allow users to input and edit data.

Query

A query is a special database feature that allows a user to ask questions and executecommands. When performing a query, you can set conditions for selecting records. It isusually used to summarise or update data such as sorting, filtering, joining tables, andperforming calculations.
