Definition
A query that performs an action on the table on which it is based.
A field whose sole purpose is to create a primary key
An automatically generated number that produces unique values for
each record
A table on which the query is based and is displayed in a datasheet
A field that appears in two or more tables and contains identical data
to relate the tables.
A query that performs calculations on the values in a field and
displays the results in a datasheet.
Monetary amounts
When multiple records are stored for the same entity
Data, which is unnecessarily duplicated.
Determines how to store the data in the field
Software that provides a system by which you can manage data.
A table, with fields displayed in columns and records displayed in
rows.
Dates or date and time combinations
A problem that occurs when a user deletes data from a database and
unintentionally deletes the only occurrence of that data in the
database
Includes gathering all existing data, researching missing and
incomplete data, and talking with users about their data output
needs. Subsequent steps in the process include putting data into
groups, called tables; identifying unique values for each record in
those tables; and designing the database to produce the desired
output.
A guarantee that there are no duplicate records in a table, that each
record is unique, and that no primary key field contains null values
A single characteristic of an entity
When a table does not contain any repeating groups
A simple database that contains a single table of information
An object that is used to view, add, delete, update, and print records
in the database. A form can be based on a table or a query.
A column in a table is considered functionally dependent on another
column if each value in the second column is associated with exactly
one value in the first column
Text that contains a hyperlink to an Internet or file location
A problem that occurs when a user cannot add data to a database
unless it is preceded by the entry of other data.
An intermediary table that contains the primary keys from two tables
that are to be joined
A field that lets you look up data in another table or in a list of values
created for the field
A set of instructions that you specify to automate certain database
tasks. A macro might contain instructions to open a specific form or
query in the database when you click a command button on a form.
A relationship in which each record in the first table matches many

records in the second table and each record in the second table
matches many records in the first table.
Long passages of data containing text and alphanumeric characters
An object that contains instructions to automate a database task.
Modules are written in VBA
A primary key that details an obvious and innate trait of a record
A process used to ensure a good database design
A field that does not contain a value, either because that value is
unknown or inapplicable
Numbers that are used in calculations
Linked or embedded objects that are created in another program
A relationship in which one record in the first table matches zero,
one, or many records in the related table.
A relationship in which one table matches exactly one record in the
related table.
When there is no longer a match between the primary key in the
primary table and the foreign keys in the related table
A Web page that lets you view and interact with data stored in an
Access database.
A condition that occurs when a field is dependent on only part of the
primary key
When a primary key uses two or more fields to create unique records
in a table
The “one” side of the 1:M relationship
A question that you ask about the data stored in a database,
The rule that if the foreign key in one table matches the primary key
in a second table, the values in the foreign key must match the
values in the primary key.
The “many” side of the relationship
A database which contains related tables through fields that contain
identical data
When a field contains more than one value
A table that is in 1NF and does not contain any partial dependencies
on the composite primary key
A computer-generated primary key that is usually invisible to users
A form that might be displayed when you open a database and
provides a controlled method for users to open the objects in a
database.
Text or alphanumeric combinations of data and numbers that are not
used in calculations
A table that is in 2NF and the only determinants it contains are
candidate keys.
A condition that occurs between two nonkey fields that are both
dependent on a third field; tables in 3NF should not have transitive
dependencies.
The programming language for Microsoft Office programs, including
Access.
A field value that is limited to yes or no, on or off, and true or false
values
