DATA is the smallest part of the database – a piece of information that is put into a field
FIELDS hold pieces of data. A group of related fields make up a record
RECORDS hold a group of related fields. A group of related records make up a table
TABLE holds a group of related records. A group of related tables make up a database
DATABASE is an electronic filing system that stores and retrieves information made up of related tables
Data Types: Number, Text, Currency, Date/Time, Boolean, Memo, Object(usually used for
picture images).
Wildcard: A character in a search that permits any character to be specified. For example, the
search criteria al* will find Alabama, already, or Albert. Ion a database search, the asterisk (*) is
the wildcard character to replace one or more letters; the question mark (?) is the wildcard
character to replace only one letter.
Multiple Criterion Filter: A database operation that displays records that meet several criteria
simultaneously.
Connectors: Words such as and, or, and not that join certain conditions together when
performing a search.
Operators: Mathematical symbols used in database filters
(>) greater than
(<) less than
(=) equal to
(>) greater than or equal to
(<) less than or equal to
When searching/filtering for text, it is often best to use the "contains" operator. This will allow you
to key in the first several identifying letters, but not the whole word or words.
QUERY SEARCH -- The process of finding all records of a database that meet a certain rule,
statement, or criterion. A search may be based on a single statement, rule, or criterion, or a
combination of statements, rules, and criteria joined by AND, OR, and AND/OR. This process is
also called a query or match in some database software programs.
SORT -- Arranging information in a specific order (usually ascending and descending).


Ascending order: method of sorting data in order from lowest to highest (A-Z) or
numerical order (0-9)
Descending order: the opposite of ascending order. Example: Reverse alphabetical
order
(Z-A) or reverse numerical is high to low (9-0).
Terms Glossary
Ascending – sorting from smallest to largest. Example: A – Z or 0 – 9.
Connectors – words like OR and AND used in searching databases which indicate whether records satisfy one rule
(OR) or if both rules must be satisfied (AND).
Counter Field – used in many databases to identify each record uniquely, like creating a unique invoice number in an

Data – the information that is entered into the computer for processing.
Database – an electronic filing system that stores and retrieves information.

Descending – sorting from largest to smallest. Example: Z – A or 9 – 0.
Design View – displays the field names and what kind of values you can enter in each field. In this view you can
