Key Terms

Byte The Field Size property that stores whole numbers from 0 to 255 in one byte. (AC 58)

composite key A primary key that consists of two or more fields. (AC 55)

Ctrl+‘ A keyboard shortcut that lets you insert in the current field the value from the same field in the previous record. (AC 79)

data redundancy A condition that occurs when you store the same data in more than one place; it wastes space and can cause inconsistencies. (AC 55)

Default Value property The property that specifies what value will appear, by default, for a field in each new record you add to a table. (AC 93)

delimited text file A type of text file in which fields of data are separated by a character such as a comma or tab. (AC 96)

Description property The optional property you can use to enter a description for a field to explain its purpose or usage. (AC 53)

Design view (for a table) The Access view you use to define or modify a table structure or the properties of the fields in a table. (AC 52)

entity integrity The condition that exists when a primary key has been specified for a table, whereby Access forces you to enter a value for the primary key field in every record in the table. (AC 68)

F6 key The function key you press to move from the Table Design grid to the Field Properties pane of the Table window in Design view. (AC 52)

import A process that allows you to copy the data from a source, without having to open the source file, and to add the imported data in an Access table. (AC 80)

Integer The Field Size property that stores whole numbers from -32,768 to 32,767 in two bytes. (AC 58)

join To relate tables using a common field. (AC 98)

join line In the Relationships window, the line that connects the common field that joins two tables. (AC 77)

Long Integer The Field Size property that stores whole numbers from -2,147,483,648 to 2,147,483,647 in four bytes. (AC 58)

null value The value that results from not entering a value for a field; a null value is not permitted for a primary key. (AC 68)

one-to-many relationship The type of database relationship that exists between two tables when one record in the first table matches zero, one, or many records in the second table, and when one record in the second table matches at most one record in the first table. (AC 76)

orphaned record A record whose matching record in either the primary or related table has been deleted. (AC 99)

primary table The “one” table in a one-to-many relationship. (AC 77)

propagate To update field property changes made in Table Design view to the corresponding property on forms and reports that include the modified field. (AC 91)

referential integrity A set of rules that Access enforces to maintain consistency between related tables when you update data in a database. (AC 99)

related table The “many” table in a one-to-many relationship. (AC 77)

Relationships window The Access window in which you define and view the relationships among a database’s tables. (AC 76)

Show Table button A button on the RELATIONSHIP TOOLS DESIGN tab that you click to open the Show Table dialog box, where you can add tables to the Relationships window. (AC 76)
