• Table – holds the actual data

• Query – searches for, sorts & retrievesdata

• Form – lets you enter & display data incustomized format

• Report – displays & prints formatted

data• Pages – publishes data into a corporate

intranet

•

Macro – automates tasks without

Queries

• Selects & defines a group of recordsthat fulfill a condition

• Forms & reports are based on

queries that pre-filter data beforeit is displayed

• Eg- show all customers in alphabeticalorder, who live in Mumbai & bought

something over the past 6 months• When you enter instructions into the

QBE design Window, the querytranslates instructions into SQL &retrieves desired data

Data Entry & DisplayForms

• Helps users get information into adatabase table quickly, easily &accurately

• Provides a more structured view of the data than what a datasheetprovides

• From this structured view, databaserecords can be viewed, added,changed or deleted

• Forms can also check the validity
