•Determine the _______________________ of fields.
Step 1−Plan and Design the Database
ƒDetermine the ____________________ of the database file.
ƒInclude all fields necessary to ensure efficient _____________________- and retrieving
of specified data.
ƒProject how the fields may be _____________________ for reporting purposes.
ƒDecide which fields would possibly be used in a variety of reports.
Step 2−Create the Database …
ƒOPEN a ______________ database file.
o What is a blank database? A database file that does not yet contain any
objects (i.e., tables, queries, reports, forms).
ƒDetermine the database ____________________ and drive location to save before
beginning the document. The default name is “db1” for the first database saved in
Access.
ƒDatabase programs assign specific file extensions to saved files. Access
uses_______________.
Step 3−Create a Table Using Design View
ƒOne method available for creating a new database table in this application
Step 4−Input and Define Fields
ƒNumbers NOT used in calculations or that contain symbols should be classified
as_________________, not as numbers.
ƒKeyboard Commands
o Arrow keys
o Cursor movement keys
o Enter key
o Tab key
o Shift tab
o Page up/down

• Vehicle identification numbers (VINs)
• Product numbers
Step 7−Input Records
What is Design View? A __________________ for adding,

_______________________ field types and descriptions, setting a primary key, and
formatting entries.
What is Datasheet View? The table view which shows the field names for
___________________ records; the view is set up in _______________ (records) and

Closing the Database
ƒClose the database file by using the _____________ command of FILE/Close or by

ƒA prompt may appear asking if changes should be______________________ .
ƒRemember, database filenames were created when a new database file
was__________________.
