used to keep the record of the personal
as well as business data with the

4. Windows. Data is stored as a number of " tables .Each
table consists of a number of " records " and each record
contains a number of " fields ", e.g. "Product code",
"Supplier", "Quantity in stock".
Access allows the user to create " forms " and "reports".
A form shows one record in a user-designed format and
allows the user to step through records one at a time. A
report shows selected records in a user-designed
format, possibly grouped into sections with different
kinds of total (including sum, minimum, maximum
average).
There are also facilities to use links (" joins ") between
tables which share a common field and to filter records
according to certain criteria or search for particular
field values.

7. Importance
Microsoft Access is an important
information management tool that
allows users to create databases to
store various kinds of information for
reference, reporting and analysis. It is
a flexible program that allows the
performance of simple end-user tasks
as well as mission critical operations.
8. Microsoft Access users can create tables,
queries, forms and reports, and connect
them together with macros. Advanced
users can use programming language
and its associated integrated
development environment to write rich
solutions with user control and
advanced data manipulation.
9. Key Terms
Database management system
(DBMS)A DBMS is an application that you use
to manage a
database.
Database
A database is a collection of related data that is
organized so that you can easily view the data
and perform operations on the data. This article
defines various database objects and database
object views.
10. Relationship
A relationship is an association between Access
tables or
queries that use related fields.
Data type
A data type determines the type of data that the
field can store. Jet data types include the following:
Text
Number
Date/Time
Currency
AutoNumber
Yes/No
11. Query
A query is an instruction to retrieve information
that is in a set of rows. You can use a query to
retrieve information from a single table or from
multiple tables based on specific criteria. You can
also use a query to modify the informationthat
you retrieved.
Select query
A select query retrieves information that you want from
one or more tables in a database. Then, the select query
presents the information that you retrieved in a format
that you want. You can also use a select query to group
records and to calculate sums counts, averages, and other
types of mathematical values.
12. Parameter query
A parameter query retrieves information in an
interactive manner. You specify the information
that you want by providing specific criteria. You can
use a parameter query
to extend the flexibility of other query types.
Action query
An action query performs an action on data in a
table. You can use an action query to insert new
records, to update existing records, or to delete
existing records.
13. Control
A control is an object on a form, on a report, or
on a data access page. You can use a control to
display data, to perform actions, or to enhance
the representation of data. For example, you
can use a text box on a form, on a report, or on
a data access page to display data. You can also
use a command button on a form to open
another form or a report. You can organize or
separate the controls in a form by using lines or
rectangles.
14. Record
A complete set of all of the data about one person,
place,
event, or idea.
Primary key
The field that makes each record in a table unique.
Foreign Key
A field in one table that also is stored in a different
table as a primary key.
Report
A printed document that displays information
professionally from a database
15. One-to-Many Relationship
Exists when each record in the first table may
match one,
more than one, or no records in the second table.
Cascades
Permit data changes to travel from one table to
another.
Cascade Delete
Searches the database and deletes all of the related
record.
PivotTable View
Provides a convenient way to summarize and
organize .data about groups of records
